On Cohomological Decomposability of Almost-Kähler Structures

, 2012
We study the J-invariant and J-anti-invariant cohomological subgroups of the de Rham cohomology of a compact manifold M endowed with an almost-K\"ahler structure (J, \omega, g).

Symplectic manifolds and cohomological decomposition

, 2012
Given a closed symplectic manifold, we study when the Lefschetz decomposition induced by the $\mathfrak{sl}(2;\mathbb{R})$-representation yields a decomposition of the de Rham cohomology.

The decoupling of moduli about the standard embedding

Journal of High Energy Physics
We study the cohomology of an elliptic differential complex arising from the infinitesimal moduli of heterotic string theory in the supergravity approximation.

Cohomological invariants of odd degree Jordan algebras [PDF]

, 2008
In this paper we determine all possible cohomological invariants of Aut(J)-torsors in Galois cohomology with mod 2 coefficients (characteristic of the base field not 2), for J a split central simple Jordan algebra of odd degree n ≥ 3.

The group of endotrivial modules for the symmetric and alternating groups. [PDF]

, 2010
We complete a classification of the groups of endotrivial modules for the modular group algebras of symmetric groups and alternating groups. We show that, for n ≥ p2, the torsion subgroup of the group of endotrivial modules for the symmetric groups is ...

Continuous Cohomology

, 2007
We investigate the continuous cohomology of infinite permutation groups on modules whose topology is profinite. To obtain acyclics we expand the class of modules to include those which are directed unions of their profinite submodules.

Cohomological finiteness properties of the Brin-Thompson-higman groups 2V and 3V

, 2010
We show that Brin's generalisations 2V and 3V of the Thompson-Higman group V are of type FP_\infty.
