Title

Quantum elliptic cohomology: a progress report

Abstract

Among the generalized cohomology theories associated to 1-dimensional (formal) groups are ordinary cohomology (G_a), complex K-theory (G_m), and elliptic cohomology (elliptic curve). In the late 1980s and early 1990s, physicists initiated quantum cohomology (Gromov-Witten theory) as the enumerative geometry associated with ordinary cohomology. A decade later, A. Givental and I established quantum K-theory. In this joint work with E. Bouaziz and I. Huq-Kuruvilla, I will report on recent (small) progress regarding the definition of the enumerative geometry of elliptic cohomology.
