(Co)homology of triassociative algebras

International Journal of Mathematics and Mathematical Sciences, 2006
We study homology and cohomology of triassociative algebras with nontrivial coefficients. The cohomology theory is applied to study algebraic deformations of triassociative algebras.

Type II string theory on Calabi-Yau manifolds with torsion and non-Abelian discrete gauge symmetries

Journal of High Energy Physics, 2017
We provide the first explicit example of Type IIB string theory compactification on a globally defined Calabi-Yau threefold with torsion which results in a four-dimensional effective theory with a non-Abelian discrete gauge symmetry. Our example is based

Heights on ‘hybrid orbits’ in Shimura varieties

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We prove the ‘hybrid conjecture’ which is a common generalisation of the André–Oort conjecture and the André–Pink–Zannier conjecture, in the case of Shimura varieties of abelian type.

An EZ${\mathcal {E}\mathcal {Z}}$‐structure for the mapping class group

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We construct a boundary for the mapping class group Mod(S)${\rm Mod}(S)$ of a surface S$S$ of finite type. The action of Mod(S)${\rm Mod}(S)$ on this boundary is minimal, strongly proximal and topologically free. The boundary is the boundary of an EZ${\mathcal {E}\mathcal {Z}}$‐structure for Mod(S)${\rm Mod}(S)$.

Syntomic cohomology and real topological cyclic homology

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We define motivic filtrations on real topological Hochschild homology and its companions. In particular, we prove that real topological cyclic homology admits a natural complete filtration whose graded pieces are equivariant suspensions of syntomic cohomology.

Cohomology and deformations of compatible 3-Lie superalgebras

Open Mathematics
In this paper, we first introduce the notions of a compatible 3-Lie superalgebras and its representation. We construct a bidifferential graded Lie algebra whose Maurer–Cartan elements are compatible 3-Lie superalgebras.

Substitutions with Vanishing Rotationally Invariant First Cohomology

Discrete Dynamics in Nature and Society, 2012
The cohomology groups of tiling spaces with three-fold and nine-fold symmetries are obtained. The substitution tilings are characterized by the fact that they have vanishing first cohomology group in the space of tilings modulo a rotation.
