Homological Projective Duality for the Pl\"ucker embedding of the Grassmannian

We describe the Kuznetsov component of the Pl\"ucker embedding of the Grassmannian as a category of matrix factorizations on an noncommutative crepant resolution (NCCR) of the affine cone of the Grassmannian. We also extend this to a full homological projective dual (HPD) statement for the Pl\"ucker embedding. The first part is finding and describing the NCCR, which is also of independent interest. We extend results of \v{S}penko and Van den Bergh to prove the existence of an NCCR for the affine cone of the Grassmannian. We then relate this NCCR to a categorical resolution of Kuznetsov. Deforming these categories to categories of matrix factorizations we find the connection to the Kuznetsov component of the Grassmannian via Kn\"orrer periodicity. In the process we prove a derived equivalence between two different NCCR's; this shows Hori duality for the group $SL$. Finally we put this all into the HPD framework.
