Asymmetry of $\mathbb P$-Functors

Algebraic Geometry 2023-03-08 v1 Category Theory

Abstract

Recently, a new definition of P\mathbb P-functors was proposed by Anno and Logvinenko. In their article, the authors wonder whether this notion is symmetric in the sense that the adjoints of P\mathbb P-functors are again P\mathbb P-functors, the analogue being true for spherical functors. We give geometric examples involving the Hilbert scheme of points on a surface that yield a negative answer.
