Analogs of the j-invariant for curves of higher genus

SPEAKER: Alexander Polishchuk

TITLE: Analogs of the j-invariant for curves of higher genus

ABSTRACT: In this talk I will explain how to generalize the construction of the j-invariant of an elliptic curve to algebraic curves of higher genus (this part of the talk will require only elementary facts from algebraic geometry of curves). I will then discuss how these invariants show up in certain A-infinity algebras associated with algebraic curves.
