Ainfinity structure on Extalgebras

"... Abstract. Let A be a connected graded algebra and let E denote its Extalgebra i Exti A (kA, kA). There is a natural A∞structure on E, and we prove that this structure is mainly determined by the relations of A. In particular, the coefficients of the A∞products mn restricted to the tensor powers of ..."

Abstract. Let A be a connected graded algebra and let E denote its Extalgebra i Exti A (kA, kA). There is a natural A∞structure on E, and we prove that this structure is mainly determined by the relations of A. In particular, the coefficients of the A∞products mn restricted to the tensor powers of Ext1 A (kA, kA) give the coefficients of the relations of A. We also relate the mn’s to Massey products.

"... The Hilbert schemes Hilbn(C 2) of points on C 2 have a rich geometric structure with many interesting links to representation theory, combinatorics and integrable systems. One reason for this is perhaps that the points of Hilbn(C 2) admit a few different algebraic incarnations ..."
