Abstract: Motivated by q-deforming of stability conditions and categories, we study the Calabi-Yau-X categories of gentle algebras from graded decoratedmarked surfaces. The string model in this case unifies the Calabi-Yau-3 case in the prequels and the usual/Calabi-Yau-infinity case (via Lagrangian immersion). This is a joint work with Akishi Ikeda and Yu Zhou.
