What is tmf

Ningchuan Zhang   [email] (UIUC)

Abstract: In short, Topological Modular Forms (tmf) is a ďuniversal elliptic cohomology theoryĒ. More precisely, it is the global section of a sheaf of $E_\infty$-ring spectra over the moduli stack of (generalized) elliptic curves. In this talk, Iíll introduce tmf and sketch the construction of it (or really this sheaf of $E_\infty$ ring spectra). If time allows, Iíll also explain its relationship to classical modular forms.

Framed Cobordism and Stable Homotopy Groups

Brian Shin   [email] (UIUC)

Abstract: I will introduce the notion of framed cobordism describe its connection to the homotopy groups of spheres. Using this connection, I will calculate several of these groups using geometry.

An Invitation to Motivic Homotopy Theory

Daniel Carmody   [email] (UIUC)

Abstract: In this talk Iíll introduce some of the basic constructions in motivic homotopy theory while trying to give motivations for some of the more complex definitions. This will be largely based on Dan Duggerís $Universal$ $Homotopy$ $Theories$ paper.
