A -Algebra of an Elliptic Curve and Eisenstein Series

  • Alexander PolishchukEmail author


We compute explicitly the A -structure on the algebra \({{\rm Ext}^*(\mathcal{O}_C \oplus L, \mathcal{O}_C \oplus L)}\) , where L is a line bundle of degree 1 on an elliptic curve C. The answer involves higher derivatives of Eisenstein series.
