On entropy of $\mathbb{P}$-twists

Abstract

We show that the P\mathbb{P}-twist associated to any P\mathbb{P}-object of a smooth project variety is not conjugate to a standard autoequivalence. This result is obtained by computing the categorical entropy functions of P\mathbb{P}-twists. We also determine the categorical polynomial entropy of spherical twists and P\mathbb{P}-twists, under an additional assumption.
