[Todor Milanov]

Dear all,

I would like to announce the following Mathematics and String theory seminar at IPMU
 
Speaker: Akhil Mathew (Harvard U)
Date:	Tue, Sep 26, 2017, 15:30 - 17:00
Place:	Seminar Room B

Title: Algebraic K-theory, polynomial functors, and lambda-rings

Abstract: The Grothendieck group K_0 of a commutative ring is
well-known to be a lambda-ring, via taking exterior powers of
modules. In joint work in progress with Barwick, Glasman, and
Nikolaus, we study space-level refinements of this structure. Namely,
we show that the K-theory space of a category is naturally
functorial for polynomial functors, and describe a universal property
of the extended K-theory functor. This leads to a natural spectral
refinement of the notion of a lambda-ring.
