Let $V$ be a $2n$-dimensional symplectic vector space, let ${\mathsf{IGr}}(k,V)$ be the isotropic Grassmannian, and let ${\mathcal{A}}_t$ be the admissible subcategories defined by…

Belmans–Smirnov's conjecture. If $X$ is neither (co)minuscule nor (co)adjoint, then $X$ is not Hochschild global; equivalently, for some $i>0$ and some $j$,

Let $\IGr(n,2n+1)$ denote the odd isotropic Grassmannian parametrizing $n$-dimensional isotropic subspaces of a $(2n+1)$-dimensional vector space equipped with a nondegenerate skew…
