Serre functor and $\mathbb{P}$-objects for perverse sheaves on ${\mathbb{P}}^n$

Lukas Bonfert, Alessio Cipriani

We show that the inverse Serre functor for the constructible derived category ${\mathbf{D}}_{\mathrm{c}}^{\mathrm{b}}({\mathbb{P}}^n)$ is given by the $\mathbb{P}$-twist at the simple perv…
