Cellular Cohomology in Homotopy Type Theory [PDF]

open access: yesLogical Methods in Computer Science, 2020
We present a development of cellular cohomology in homotopy type theory. Cohomology associates to each space a sequence of abelian groups capturing part of its structure, and has the advantage over homotopy groups in that these abelian groups of many ...

Coarse Sheaf Cohomology

open access: yesMathematics, 2023
A certain Grothendieck topology assigned to a metric space gives rise to a sheaf cohomology theory which sees the coarse structure of the space. Already constant coefficients produce interesting cohomology groups. In degree 0, they see the number of ends

Cohomology of simple modules for sl3(k) in characteristic 3 [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper we calculate cohomology of a classical Lie algebra of type A 2 over an algebraically field k of characteristic p = 3 with coefficients in simple modules.

Quantum cohomology as a deformation of symplectic cohomology

open access: yesJournal of Fixed Point Theory and Applications, 2022
AbstractWe prove that under certain conditions, the quantum cohomology of a positively monotone compact symplectic manifold is a deformation of the symplectic cohomology of the complement of a simple crossings symplectic divisor. We also prove rigidity results for the skeleton of the divisor complement.

From β to η: a new cohomology for deformed Sasaki-Einstein manifolds

open access: yesJournal of High Energy Physics, 2022
We discuss in detail the different analogues of Dolbeault cohomology groups on Sasaki-Einstein manifolds and prove a new vanishing result for the transverse Dolbeault cohomology groups H ∂ ¯ p 0 k $$ {H}_{\overline{\partial}}^{\left(p,0\right)}(k ...

Satellites of Functors for Nonassociative Algebras with Metagroup Relations

open access: yesMathematics, 2022
The article is devoted to non-associative algebras with metagroup relations and modules over them. Their functors are studied. Satellites of functors are scrutinized. An exactness of satellite sequences and diagrams is investigated.

Motives with modulus, II: Modulus sheaves with transfers for proper modulus pairs [PDF]

open access: yesÉpijournal 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.

On Rham cohomology of locally trivial Lie groupoids over triangulated manifolds

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2020
Based on the isomorphism between Lie algebroid cohomology and piecewise smooth cohomology of a transitive Lie algebroid, it is proved that the Rham cohomology of a locally trivial Lie groupoid G on a smooth manifold M is isomorphic to the piecewise Rham ...

Splitting Extensions of Nonassociative Algebras and Modules with Metagroup Relations

open access: yesAxioms, 2022
A class of nonassociative algebras is investigated with mild relations induced from metagroup structures. Modules over nonassociative algebras are studied. For a class of modules over nonassociative algebras, their extensions and splitting extensions are
