Jonathan Cox
"On the Cohomology of Stable Map Spaces" by Behrend and O'Halloran
Abstract: A highly condensed summary of the paper will be presented. We will fill in details in future talks as time and understanding permit. I will outline the method used to describe the "cohomology ring of degree 3 maps into infinite-dimensional projective space."
Tuesday, April 2, 4 p.m., 241 Altgeld Hall
Jonathan Cox
On the Cohomology of Stable Map Spaces by Behrend and O'Halloran, Part II
Abstract: We will extend to P^n the constructions done for P^1 in the first talk. Hopefully we will also compute the cohomology ring of stable maps into infinite dimensional projective space with image of degree 3. We may also consider the degree 2 case.
Tuesday, April 9, 4 p.m., 241 Altgeld Hall
Xinyun Zhu
"Resolving 3-dimensional toric singularities" by Dimitrios I. Dais
Tuesday, April 16, 4 p.m., 241 Altgeld Hall
Xinyun Zhu
Continuation of "Resolving 3-dimensional toric singularities" by Dimitrios I. Dais
