Hochschild cohomology and deformations of $P$ -functors

Ciaran Meachan, Theo Raedschelders

Given a split $P$ -functor $F : D^{b} (X) \to D^{b} (Y)$ between smooth projective varieties, we provide necessary and sufficient conditions, in terms of the Ho…

Derived equivalent Hilbert schemes of points on K3 surfaces which are not birational

Ciaran Meachan, Giovanni Mongardi, Kota Yoshioka

We provide a criterion for when Hilbert schemes of points on K3 surfaces are birational. In particular, this allows us to generate a plethora of examples of non-birational Hilbert…
