We generalise some results of Dave Benson on the homology of the loop space of a
p-completed classifying space of a finite group. In particular, we show that the loop space
homology of a plus construction (in the sense of Quillen) of the nerve of a small category can be
computed in purely algebraic terms as the homology of a chain complex of projective
RC-modules satisfying a certain list of algebraic conditions that determine it uniquely up to chain
homotopy. This is joint work with Ran Levi and Bob Oliver.Topology Seminar - "Massey Products and Monent-Angle Complexes", Abigail Linton (Southampton)https://cdn.southampton.ac.uk/assets/imported/transforms/site/seminar/PageThumbnail/9ED304230BCD44F1B45BB1F887D7EF30/Topology.JPG_SIA_JPG_fit_to_width_XL.jpghttps://www.southampton.ac.uk/maths/news/seminars/2018/12/03-topology-seminar.pageMon, 03 Dec 2018 00:00:00 +0000

Massey products are higher cohomology operations that are important across algebra, topology and geometry, but are notoriously extremely difficult to compute. As a result, there are relatively few explicit examples of non-formal manifolds, that is, of manifolds with a non-trivial Massey product in their cohomology. In this talk, I present methods to create non-formal manifolds through the moment-angle complex construction. Moment-angle complexes have a natural underlying combinatorial structure that allows us to study obstructions to Massey products in cohomology. In particular, we will see how certain operations on simplicial complexes, such as stellar subdivisions and edge contractions, can be used to create moment-angle complexes with non-trivial n-Massey products on classes of any given degree.

There are many examples of groups that act on contractible simplicial complexes with a strict fundamental domain, e.g. free products with amalgamation, graph products of groups or more generally groups acting chamber transitively on buildings. In this talk, primary examples will be finitely generated Coxeter groups acting on associated Davis complex. We will discuss a
construction that replaces the Davis complex with a “simpler" complex called the Bestvina complex. This complex will have the smallest possible dimension equal to the virtual cohomological dimension of the group and will be equivariantly homotopy equivalent to the Davis complex. This will allow us to compute the Bredon cohomological dimension of the group with respect to the family of finite subgroups. I will give examples of the Bestvina complex and
discuss some applications and generalisations. One such application is that if a group acts on a contractible complex X with a strict fundamental domain and also has Bredon cohomological dimension at most one for the family of stabiliser subgroups, then X equivariantly deformation retracts onto a tree.Topology Seminar https://cdn.southampton.ac.uk/assets/imported/transforms/site/seminar/PageThumbnail/9ED304230BCD44F1B45BB1F887D7EF30/Topology.JPG_SIA_JPG_fit_to_width_XL.jpghttps://www.southampton.ac.uk/maths/news/seminars/2018/11/19-topology-seminar.pageMon, 19 Nov 2018 00:00:00 +0000

The family of the complex Grassmann manifolds G_(n,k) with the canonical action of the algebraic torus, and therefore the compact torus T^n, is well known. The interest in the description of these actions is motivated by classical and modern problems in algebraic geometry, algebraic and equivariant topology, symplectic geometry and enumerative combinatorics. In the well known papers of Gel'fand-Serganova, Goresky-MacPherson, Kapranov, etc, the (algebraic torus)-equivariant topology of G_(n,k) is studied.

I will discuss the topological invariant TC(X) reflecting the complexity of algorithms for autonomous robot motion. Here, X stands for the configuration space of a system and TC(X) is the minimal number of continuous rules which are needed to construct a motion planning algorithm in X. I shall mainly focus on the case when the space X is aspherical; then the number TC(X) depends only on the fundamental group π = π1(X) and it is denoted TC(π). In the talk I shall characterise TC(π) in terms of various classifying spaces associated with the group π. The equivariant Bredon cohomology provides lower and upper bounds for TC(π).

Let G be a very nice p-adic analytic group; I have in mind examples such as
Gl_n(Z_p). The category of continuous G-modules has a very elegant theory of duality reflecting Poincaré duality for G. We would very much like to extend this to stable homotopy theory where, in various contexts, it would help explain some deep structure we have seen so far only through computations. It is easy enough to define the dualizing objects, but then we are left with understanding them. It turns out that if we are only interested in finite subgroups of G (which
would be a serious start) we can get away with classical computations with Stiefel-Whitney classes. This is an on-going project with Agnès Beaudry, Mike Hopkins, and Vesna Stojanoska.

Abstract: In this talk we consider torus actions on moment-angle complexes and calculate the cohomology of their quotient spaces. From the Taylor resolution, a differential graded algebra is obtained with homology isomorphic to the cohomology of quotient spaces. In the case of circle actions on moment-angle complexes, we relate the homology groups of this DGA to weighted homology groups of a filtration of simplicial complexes.Topology Seminar - Cohomology computations with the evaluations fibration, Matt Burfitt (Southampton)https://cdn.southampton.ac.uk/assets/imported/transforms/site/seminar/PageThumbnail/3B8FD10817A940DEAD581D8C26978DDE/Pure.JPG_SIA_JPG_fit_to_width_XL.jpghttps://www.southampton.ac.uk/maths/news/seminars/2018/02/19-topology-burfitt-seminar.pageMon, 19 Feb 2018 00:00:00 +0000

In this talk I would like to disuss the details of my work on the cohomology
of the free loop space of complete flag manifolds. However I believe the constructions exhibited can more widely applied. I will demonstrate the techniques I used to study rank 2 flag manifolds by giving the details of the constructions in the case of L(SU(3)/T). In particular I will derive the differentials in the cohomology Leray-Serre spectral of the evaluation fibration of SU(3)/T. Then examine how the theory of Gröbner basis can be applied to provide an analysis of the spectral sequence. Finally I will talk about solving
the arising extension problem to deduce the cohomology algebra.

We consider the canonical action of the maximal torus (algebraic
or compact) on a homogeneous space G/P, where G is a compact, complex,
semisimple Lie group and P is its standard parabolic subgroup. We will explain
how this action relates to the action of the same torus on the corresponding
complex projective space via a Plucker embedding. We demonstrate this
relation in the case of the complex Grassmann manifold and discuss related
problems.

Abstract: Gauge groups are topological groups of automorphisms of principal bundles. Consider all principal G-bundles over X for fixed G,X. Then we have a family of gauge groups and it is interesting to count the number of specific equivalence classes. Crabb and Sutherland showed that if G is a compact connected Lie group and X is a finite complex, then the number of distinct homotopy types of gauge groups is finite. Later, this finiteness is generalized by Tsutaya to A_n-types for finite n. In this talk, I will explain infiniteness of A_infinity-types when X is a sphere and G is a compact connected simple Lie group. This is a joint work with M. Tsutaya.

I will recall the classica notion of nonabelian cohomology of groups and talk about why there are only zero-th and first dimensional cohomology groups. This is a special case of the cohomotopy of cosimplicial groups, which are also only defined in the zero-th and first dimension in general. I introduce a new class of cosimplicial groups, called centralised cosimplicial groups, for which I was able to define a second cohomotopy, with all the expected properties. The main examples of such cosimplicial groups come from 2-categories.The Poincare-Hopf Theorem for line fields revisitedhttps://cdn.southampton.ac.uk/assets/imported/transforms/site/seminar/PageThumbnail/9ED304230BCD44F1B45BB1F887D7EF30/Topology.JPG_SIA_JPG_fit_to_width_XL.jpghttps://www.southampton.ac.uk/maths/news/seminars/2017/01/30-mark-grant-seminar-topology.pageMon, 30 Jan 2017 00:00:00 +0000

A line field is a smooth assignment of a tangent line to each point of a manifold (and therefore may be thought of as the projective analogue of a vector field). Such objects find applications in soft matter physics, where they are used to model ordered media made up of rod-shaped molecules, such as nematic liquid crystals.
I will present an analogue of the Poincaré-Hopf Theorem for line fields with point singularities. For orientable surfaces, such a result appears in Hopf's 1956 lecture notes on Differential Geometry. In 1955 Markus presented such a result in all dimensions, but his statement is only valid in even dimensions greater than 2. In 1984 Jänich presented a Poincaré-Hopf Theorem for line fields with more complicated singularities, focussing on the complexities arising in the generalised setting. Our proof is a correction of Markus' proof, and is valid in all dimensions.

Given a self-transverse immersion f: M^{2n+2} \to R^{4n+2} of a compact closed manifold M, then its double point self-intersection manifold L^2 \to R^{4n+2} is a compact closed surface which is necessarily a boundary. If the normal bundle of the immersion f has a stable complex structure than the double point surface has a stably complex structure and so is bordant as a stably complex manifold to a multiple of CP^1 with its canonical stably complex structure. We consider what multiples can arise as double point surfaces.

A-infinity resolutions and the Golod property for monomial ringshttps://cdn.southampton.ac.ukhttps://www.southampton.ac.uk/maths/news/seminars/2016/11/a-infinity-resolutions-and-the-golod-property-for-monomial-rings.pageMon, 14 Nov 2016 00:00:00 +0000
[14:00 - 15:00, 14 November 2016]
A classic result by Serre tells us that the Poincaré series of a monomial ring R is bounded above by a rational function involving the Betti numbers of the Koszul homology of R. A ring is called Golod if the two expressions are equal. One can show that R is Golod if and only if all Massey products on Koszul homology vanish. However, in general it is hard to determine when Massey products vanish.
In this talk we will discuss a new approach to determine Golodness using A-infinity algebras. We will show that Golodness is equivalent to having a minimal A-infinity structure on a free resolution. Using this description we show that for a large class of monomial rings Golodness is equivalent to the vanishing of the product on Koszul homology. If time permits, we give a combinatorial description of Golodness for monomial rings whose Lyubeznik resolution is minimal.
