Description
Abstract: As one varies the stability condition/energy of a GLSM, the associated derived categories can often be embedded in one another. As a consequence many GLSMs have a (sometimes fractional) Calabi-Yau phase. Mathematically, this can be interpreted as a full Calabi-Yau subcategory of the derived category of the GLSM. I will survey this story following joint work with Ballard-Katzarkov and Kelly.
