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 seminar website is here.
Hours and Venue: Tuesdays, 3:30pm - 4:30pm in MATH 350
The classical smooth Morse theory provides a way to determine the homotopy and homology type of a smooth manifold by way of sublevelset filtrations of suitable smooth functions. The discrete case provides a comparable notion for simplicial complexes that is suitable for computations. In either case, we obtain a sublevelset persistent homology and a method for pairing bars in the barcode with critical points or simplices witnessing the birth and death of cycles. When a stratification is present, we can modify these theories to accommodate this extra data. In this talk we will introduce and relate these theories, providing examples of algorithms involved with applying these for topological data analysis.

We will explain how to construct explicit quasi-isomorphisms computing the cyclic and periodic cyclic homology of crossed-product algebras arising from group actions on manifolds. This simplifies and clarifies earlier results of Brylinski–Nistor and Crainic. We will also review the necessary background on cyclic and periodic cyclic homology and paracyclic spaces, and introduce para-S-modules, a new paracyclic version of the S-modules of Jones and Kassel.
