DESCRIPTION:Title: <a href="https://researchseminars.org/talk/paris-algebr
 a-seminar/227/">Graded Higgs categories</a>\nby Yilin Wu (Luxembourg) as p
 art of Paris algebra seminar\n\n\nAbstract\nLet A be a differential bigrad
 ed k-algebra and let e be an idempotent of A. Under suitable assumptions o
 n the pair (A\,e)\, we define the graded Higgs category H and the graded r
 elative cluster category C. We show that H carries a Frobenius extriangula
 ted structure\, and that its stable category admits a silting object. Exam
 ples arise from Keller-Scherotzke's work on graded singular Nakajima categ
 ories and from graded maximal Cohen-Macaulay modules over isolated singula
 rities. This is a report on ongoing joint work with Li Fan.\n\nThis talk w
 ill take place in hybrid mode at the Institut Henri Poincaré.\n
