Events for 10/07/2020 from all calendars

Geometry Seminar

Time: 12:00PM - 1:30PM

Location: zoom

Speaker: J. Weyman, U. Krakow

Title: Structure of finite free resolutions.

Abstract: In this talk I will describe the structure of finite free resolutions via so-called generic rings. In the first part I will go through older results of Buchsbaum-Eisenbud and Hochster. Then I will describe a more recent connection to the combinatorics of the root systems of T-shaped diagrams $T_{p,q,r}$.

Noncommutative Geometry Seminar

Time: 1:00PM - 2:00PM

Location: Zoom 942810031

Speaker: Bogdan Nica, IUPUI

Title: On norms of averaging operators on geometric groups

Abstract: Given a finite subset S of an infinite discrete group, consider the operator \lambda(S)=\sum_{g\in S} \lambda(g). I will discuss the problem of estimating the operator norm of \lambda(S) in certain `geometric' situations.

Topology Seminar

Time: 4:00PM - 5:00PM

Location: ZooM

Speaker: Prasit Bhattacharya, University of Notre Dame

Title: The stable Adams conjecture

Abstract: The Adams conjecture, perhaps one of the most celebrated results in the subject of stable homotopy theory, was resolved by Quillen and Sullivan independently in the 1970s. Essentially, the Adams conjecture says that the q-th Adams operation composed with the J-homomorphism can be deformed continuously to the J-homomorphism itself if localized away from q. The stable enhancement of the Adams conjecture (which is only possible in the complex case) claims that this deformation can be achieved within the space of infinite loop maps from BU to the classifying space of spherical bundles. We recently found that the only accepted proof of the stable Adams conjecture, which is due to Friedlander (1980), has a mistake. In this talk, I will explain the mistake, reformulate the statement of the stable Adams conjecture, sketch our new proof of the stable Adams conjecture and discuss some of the ramifications. This is joint work with N. Kitchloo.

Panel: How (and Why) to Write Diversity Statements

Time: 4:00PM - 5:00PM

Location: Zoom

Speaker: Panelists

Description: Join us in a discussion on how and why to write diversity statements. We will feature various panelists with experience in either reading or writing diversity statements. Some of our panelists include Dr. Edray Goins from Pomona College, Dr. Rolando de Santiago from UCLA, Dr. Ola Sobieska from the University of Wisconsin-Madison, Dr. Duane Nykamp from the University of Minnesota, and Dr. Anthony Várilly-Alvarado from Rice University. While purposed for answering graduate students’ questions on the importance of diversity statements and how to write one, this event is open to everyone in the department wishing to learn a little more about diversity and diversity statements.
