Optimal semigroup estimates and functional calculus for the Laplacian on weighted Sobolev spaces

Floris Roodenburg

In this paper, we consider the Laplace operator on the half-space with Dirichlet and Neumann boundary conditions. These operators are studied on Sobolev spaces with power weights m…

Chow classes of orbit closures of skew-symmetric matrix pencils

Ari Krishna

The paper determines the Chow class of each of the eleven PGL(V)-orbit closures of skew‑symmetric 6×6 matrix pencils inside the Grassmannian Gr(2, Λ²V^∨), expressed in the Schubert…

A universal discriminant formula for pencils of quadrics

Ari Krishna

Let $V$ be a vector space of dimension $n + 1$ over an algebraically closed field $k$ of characteristic zero, and let $G_{n} = Gr (2, Sym^{2} V^{\lor})$ …

Pointed Evaluation Fibers of Rational Curves on del Pezzo Manifolds

Ari Krishna

Let $X$ be a Picard-rank-one del Pezzo manifold of dimension $n \geq 4$ over an algebraically closed field of characteristic zero. Okamura proved that the unpointed Kontsevich space…

All Quiet on the Exceptional Locus

Ari Krishna

We study admissible subcategories of the bounded derived category of a smooth projective surface that are supported on the exceptional locus of a birational morphism. We prove that…

On the Codimension-1 $PGL_{4}$ Orbit Closures in $Gr (2, 10)$

Ari Krishna

We study the natural action of $PGL (V)$ on the Grassmannian $G = Gr (2, Sym^{2} V^{\lor})$ , where $dim V = 4$ and points of $G$ are pencils of quadric…
