Query: The fundamental theorem of homological projective duality via variation
  of GIT stability   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 varieties to nice subcategories of smooth
quotient stacks, and moreover shows that the line bundles polarising the
varieties in HP duality do not have to be globally generated.
  The proof combines ideas from Kuznetsov's original proof with ideas from work
of Ballard-Deliu-Favero-Isik-Katzarkov.
