Maxim Stykow (UBC)
Location:

University of British Columbia

Topic:

Working seminar on homotopy theory of moduli spaces

Description:

Sheaves of Categories and the Main Theorem

After talking about how a sheaf of categories gives rise to a topological category, I will finish the proof of the main theorem of Galatius, Madsen, Weiss and Tillmann which states that the classifying space of the cobordism category is weakly homotopy equivalent to the infinite loop space of the Thom spectrum.

Schedule:

2:00pm-3:00pm, WMAX 110
