David Favero: Semi-orthogonal decompositions and phase change
Semi-projective toric varieties can be described as GIT quotients of
the spectrum of the Cox ring. Choosing an element of the Cox ring,
gives a toric LG model. Varying the GIT quotient yields new LG models
whose categories of B-branes are related by semi-orthogonal
decompositions. This is a generalization of work of M. Herbst and J.
Walcher and is part of joint work in progress with L. Katzarkov and M.
Ballard.
