DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGeNT/22/">
 Lie structures in derived categories</a>\nby Shengyuan Huang (Birmingham) 
 as part of Leiden Algebra\, Geometry\, and Number Theory Seminar\n\n\nAbst
 ract\nFor a closed embedding $X\\hookrightarrow S$ of smooth schemes with 
 a first order splitting\, the derived self-intersection $X\\times^R_SX$ an
 d the shifted normal bundle $N_{X/S}[-1]$ carry Lie structures. In this ta
 lk\, we discuss an analogue of the exponential map from a Lie algebra to t
 he corresponding Lie group in this setting and its application in the stud
 y of orbifold Hochschild cohomology product.\n
