SUMMARY:The A-infinity structure on the Ext algebra of a commutative ring
DESCRIPTION:Speaker: Vincent Galinas\, University of Toronto\n\nLet R be a Noetherian k-algebra, and for simplicity assume that R is augmented of finite type over k of characteristic zero. The minimal semifree model of R is given by the Chevalley-Eilenberg construction of a Lie(-infinity) coalgebra whose dual is the homotopy Lie algebra $\pi$ of R. Taking the …
