Abstract: The classical degree-genus formula computes the genus of a nonsingular algebraic curve in the complex projective plane. The well-known Thom conjecture posits that this is a lower bound on the genus of smoothly embedded, oriented and connected surface in CP2. The conjecture was first proved twenty-five years ago by Kronheimer and Mrowka, using Seiberg-Witten invariants. In this talk, we will describe a new proof of the conjecture that…
Title of talk:   An introduction to contact geometry. We'll be discussing basic notions and the relevance of contact geometry to low-dimensional topology.
Colleen Kuusinen will come and talk to us about active learning.
Title: Products in the cohomology of local Hopf algebras Abstract: This is joint work with Lucho Avramov and Srikanth Iyengar. Suppose that A is a local commutative Hopf algebra over a field of prime characteristic. The question that we investigate is: How does the a change in the coalgebra structure alter the action of the cohomology ring on the cohomology of modules? This question is particularly interesting in the case that A is the group…
