DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/95/">
 Relative graded Brauer graph algebras and stability conditions</a>\nby Mer
 lin Christ (Institut de Mathématiques de Jussieu\, France) as part of Lon
 gitudinal Algebra and Geometry Open ONline Seminar (LAGOON)\n\n\nAbstract\
 nWe consider a class of dg-algebras which generalize Brauer graph algebras
 \, called relative graded Brauer graph algebras. Their Koszul dual dg-alge
 bras are given by finite group quotients of relative Ginzburg algebras ass
 ociated with n-angulated surfaces. By constructing a partial geometric mod
 el of the derived category\, we fully describe the finite heart tilting th
 eory. This leads to a description of the space of Bridgeland stability con
 ditions in terms of quadratic differentials. Based on joint work with Y. Q
 iu and F. Haiden.\n\nhttps://uni-koeln.zoom.us/j/91875528987?pwd=US8wdjNrW
