Motives with modulus, II: Modulus sheaves with transfers for proper modulus pairs [PDF]
Épijournal de Géométrie Algébrique, 2021 We develop a theory of sheaves and cohomology on the category of proper modulus pairs. This complements [KMSY21], where a theory of sheaves and cohomology on the category of non-proper modulus pairs has been developed.

Hochschild and block cohomology varieties are isomorphic [PDF]
, 2010 We show that the varieties of the Hochschild cohomology of a block algebra and its block cohomology are isomorphic, implying positive answers to questions of Pakianathan and Witherspoon in [16] and [17].

Symmetry protected topological orders and the group cohomology of their symmetry group [PDF]
, 2011 Symmetry protected topological (SPT) phases are gapped short-range-entangled quantum phases with a symmetry G. They can all be smoothly connected to the same trivial product state if we break the symmetry.

Equivariant Lie–Rinehart cohomology; pp. 294–300 [PDF]
Proceedings of the Estonian Academy of Sciences, 2010 In this paper we study LieâRinehart cohomology for quotients of singularities by finite groups, and interpret these cohomology groups in terms of integrable connection on modules.

Gromov-Witten classes, quantum cohomology, and enumerative geometry [PDF]
, 1994 The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic treatment of Gromov-Witten classes, and a discussion of their

Maximal equicontinuous factors and cohomology for tiling spaces [PDF]
, 2012 We study the homomorphism induced on cohomology by the maximal equicontinuous factor map of a tiling space. We will see that this map is injective in degree one and has torsion free cokernel.

Khovanov homology from Floer cohomology [PDF]
Journal of The American Mathematical Society, 2015 This paper realises the Khovanov homology of a link in S 3 S^3 as a Lagrangian Floer cohomology group, establishing a conjecture of Seidel and the second author.

Contextuality, Cohomology and Paradox [PDF]
Annual Conference for Computer Science Logic, 2015 Contextuality is a key feature of quantum mechanics that provides an important non-classical resource for quantum information and computation. Abramsky and Brandenburger used sheaf theory to give a general treatment of contextuality in quantum theory ...

A New Cohomology Theory for Orbifold
, 2001 Motivated by orbifold string theory, we introduce orbifold cohomology group for any almost complex orbifold and orbifold Dolbeault cohomology for any complex orbifold.
