This is the departmental seminar on algebraic topology and related topics.
We usually have a semester theme, for which speakers from the department are invited to contribute talks, and external guest speakers who will give talks on current research in topology. The semester themes for Fall 2022 are "sheaves and logic" and "applied topology". The seminar website is here.
Hours and Venue: Tuesdays, 3:30pm - 4:30pm in MATH 350
I will talk about equivariant homotopy theory and its role in the proof of the Segal conjecture and the Kervaire invariant one problem. Then, I will talk about chromatic homotopy theory and its role in studying the stable homotopy groups of spheres. These newly established techniques allow one to use equivariant machinery to attack chromatic computations that were long considered unapproachable.

The (classical) Adams spectral sequence was one of the first major computational tools developed in stable homotopy theory. In this talk we will give an overview of the construction of the spectral sequence and, time permitting, perform some low-dimensional computations.

In this talk, I willI introduce a general framework for how we can understand properties of power operations via "Eulerian sequences". I will also discuss how various properties of these operations are encoded by these sequences (e.g. geometric fixed points, Cartan formula, etc...). When the group of equivariance is trivial or has order two, all known Steenrod and Dyer-Lashof operations are recovered in this framework. As a final application, I will show how to construct new nonzero mod p Steenrod and Dyer-Lashof operations for every finite group. This is based on joint work with Prasit Bhattacharya and Foling Zou.
