On the Weil-étale Cohomology of S-Integers [PDF]
, 2012 We generalize the Lichtenbaum's prototype of Weil-étale cohomology to S-integers and study its relation to the Tate sequences. In the final part, we present a more natural way to define Weil-étale cohomology for one-dimensional arithmetic schemes ...

Cohomology of D-complex manifolds [PDF]
, 2012 In order to look for a well-behaved counterpart to Dolbeault cohomology in D-complex geometry, we study the de Rham cohomology of an almost D-complex manifold and its subgroups made up of the classes admitting invariant, respectively anti-invariant ...

Vertex algebra of extended operators in 4d N=2 superconformal field theories. Part I
Journal of High Energy Physics, 2023 We construct a class of extended operators in the cohomology of a pair of twisted Schur supercharges of 4d N $$ \mathcal{N} $$ =2 SCFTs. The extended operators are constructed from the local operators in this cohomology — the Schur operators — by a ...

The Support of Local Cohomology Modules [PDF]
International Mathematics Research Notices, 2017 We describe the support of $F$-finite $F$-modules over polynomial rings $R$ of prime characteristic. Our description yields an algorithm to compute the support of such modules; the complexity of our algorithm is also analyzed. To the best of our knowledge, this is the first algorithm to avoid extensive use of Gröbner bases and hence of substantial ...

On the cohomological dimension of the localization functor [PDF]
Proceedings of the American Mathematical Society, 1990 The localization functor of the title is defined by \(\Delta_{\lambda}(V)={\mathcal D}_{\lambda}\otimes_{{\mathcal U}_{\lambda}}V\), where \(\lambda\) is an element of the dual of a fixed Cartan subalgebra of a complex semisimple Lie algebra \({\mathfrak g}\), \({\mathcal U}_{\lambda}\) the quotient of the enveloping algebra of \({\mathfrak g}\) by the

Socle finiteness of the local cohomology
Rocky Mountain Journal of Mathematics, 2011 Let \(R\) be a commutative local noetherian ring. Finiteness properties of local cohomology modules over \(R\) are among the basic topics of local cohomology theory. One of the main question is as follows ``Let \(I\) be an ideal of \(R\). Is the socle of \(H^n_I(R)\) finitely generated?'' A positive answer to this question for all regular local ring ...

UPPER BOUNDS FOR FINITENESS OF GENERALIZED LOCAL COHOMOLOGY MODULES [PDF]
Journal of Algebraic Systems, 2013 Let $R$ be a commutative Noetherian ring with non-zero identity and $fa$ an ideal of $R$. Let $M$ be a finite $R$--module of finite projective dimension and $N$ an arbitrary finite $R$--module.

Quantum cohomology of the odd symplectic Grassmannian of lines [PDF]
, 2013 Odd symplectic Grassmannians are a generalization of symplectic Grassmannians to odd-dimensional spaces. Here we compute the classical and quantum cohomology of the odd symplectic Grassmannian of lines.
