A counterexample to the birational Torelli problem for Calabi-Yau threefolds
John Christian Ottem, Jørgen Vold Rennemo
The Grassmannian Gr(2,5) is embedded in via the Plücker embedding. The intersection of two general PGL(10)-translates of Gr(2,5) is a Calabi-Yau 3-fold X, and the inter…

The fundamental theorem of homological projective duality via variation of GIT stability
Jørgen Vold Rennemo
We reprove Kuznetsov's "fundamental theorem of homological projective duality" using LG models and variation of GIT stability. This extends the validity of the theorem from smooth…

We prove a version of the classical 'generic smoothness' theorem with smooth varieties replaced by non-commutative resolutions of singular varieties. This in particular implies a n…
