DESCRIPTION:The derived category of coherent sheaves on a cubic fourfold h
as a subcategory which can be thought as the derived category of a non-c
ommutative K3 surface. This subcategory was studied recently in the work
of Kuznetsov and Addington-Thomas\, among others. In this talk\, I will p
resent joint work with Bayer\, Lahoz\, Nuer\, Perry\, Stellari\, on how t
o construct Bridgeland stability conditions on this subcategory. This pro
ves a conjecture by Huybrechts\, and it allows to start developing the mo
duli theory of semistable objects in these categories\, in an analogue wa
y as for the classical Mukai theory for (commutative) K3 surfaces. I will
also discuss a few applications of these results.\n\nhttps://indico.math
