DESCRIPTION:Speakers: Jiaqi Fu (Université de Toulouse)\n\nAn Eclair of n
 on-abelian derived category.\nShort: Nonabelian derived category is a form
 al language spoken by both homotopists and\nalgebraic geometers.\nLong: No
 nabelian derived category is a common language shared by modern algebraic 
 topologists\nand algebraic geometers. I will provide a somehow messy but j
 uicy introduction (like an ´eclair\n!) to this framework by discussing th
 e following questions: what exactly is a nonabelian derived\ncategory (fol
 lowing Quillen\, Lurie\, and others) ? Why does it appear so naturally in 
 both homotopy\ntheory and algebraic geometry? And\, putting aside many mis
 placed criticisms\, how does this sort of\n“abstract nonsense” contrib
 ute to actual computation ? I will also mention a small result of me and\n
 Nuiten concerning a kind of “dual analogue” of Steenrod operations.\n\
