Stability and certain $\mathbb{P}^n$-functors (2206.04578v2)

Abstract: Let $X$ be a K3 surface. We prove that Addington's $\mathbb{P}^n$-functor between the derived categories of $X$ and the Hilbert scheme of points $X^{[k]}$ maps stable vector bundles on $X$ to stable vector bundles on $X^{[k]}$, given some numerical conditions are satisfied.
