Title: Stringy bundles and ring spectra

Abstract:  In their work, P. Hu and I. Kriz considered Stringy bundles to give a geometric description of Elliptic cohomology. These are geometric objects over a fixed elliptic curve. After some inverting process, they were able to obtain a multiplicative infinite loop space out of these objects.

In this talk, I will present  machinery that can be used directly on a slight modification of stringy bundles, that produces a strictly commutative ring spectrum out of these objects. 

This construction  relies on the concept of  Multicategories and the recent work of Elemdorf and Mandell.
