sl(2)-Trivial Deformations of Vect_{Pol}(R)-Modules of Symbols
Symmetry, Integrability and Geometry: Methods and Applications, 2008 We consider the action of Vect_{Pol}(R) by Lie derivative on the spaces of symbols of differential operators. We study the deformations of this action that become trivial once restricted to sl(2).

Rational cohomology of M4,1$\mathcal {M}_{4,1}$
Mathematische Nachrichten, Volume 298, Issue 3, Page 1041-1061, March 2025.Abstract We compute the rational cohomology of the moduli space M4,1$\mathcal {M}_{4,1}$ of nonsingular genus 4 curves with one marked point, using Gorinov–Vassiliev's method.

On the rigid cohomology of certain Shimura varieties [PDF]
, 2014 We construct the compatible system of l-adic representations associated to a regular algebraic cuspidal automorphic representation of $$GL_n$$GLn over a CM (or totally real) field and check local–global compatibility for the l-adic representation away ...

Cohomologies of the Poisson superalgebra [PDF]
Theoretical and Mathematical Physics, 2005 We consider antiPoisson superalgebras realized on the smooth Grassmann-valued functions with compact supports in R^n and with the grading inverse to Grassmanian parity. The lower cohomologies of these superalgebras are found.

Biflat F‐structures as differential bicomplexes and Gauss–Manin connections
Bulletin of the London Mathematical Society, Volume 57, Issue 3, Page 786-808, March 2025.Abstract We show that a biflat F‐structure (∇,∘,e,∇∗,∗,E)$(\nabla,\circ,e,\nabla ^*,*,E)$ on a manifold M$M$ defines a differential bicomplex (d∇,dE∘∇∗)$(d_{\nabla },d_{E\circ \nabla ^*})$ on forms with value on the tangent sheaf of the manifold. Moreover, the sequence of vector fields defined recursively by d∇X(α+1)=dE∘∇∗X(α)$d_{\nabla }X_{(\alpha +1)}

The Shi variety corresponding to an affine Weyl group
Bulletin of the London Mathematical Society, Volume 57, Issue 3, Page 913-940, March 2025.Abstract Let W$W$ be an irreducible Weyl group and Wa$W_a$ its affine Weyl group. In this article we show that there exists a bijection between Wa$W_a$ and the integral points of an affine variety, denoted X̂Wa$\widehat{X}_{W_a}$, which we call the Shi variety of Wa$W_a$.

Local Cohomology: An Algebraic Introduction with Geometric Applications
, 1998 This book provides a careful and detailed algebraic introduction to Grothendieck’s local cohomology theory, and provides many illustrations of applications of the theory in commutative algebra and in the geometry of quasi-affine and quasi-projective ...
