Dynamical Systems Seminar: Jeremy Kahn - Can we prove MLC before OpenAI does?
  •   2:15pm - 3:15pm

Speaker:   Jeremy Kahn

Abstract:  
It has been known for forty years that the local connectivity of the Mandelbrot set M reduces to showing that there is a unique z |-> z^2 + c that is infinitely renormalizable with a given sequence of types. This in turn reduces, at least morally, to controlling the geometry at all scales for each such dynamical system. We’ll review an ontology of types and then outline work completed and in progress on some cases of sequences of types, by subsets of authors taken from Misha, Dima, Alex Kapiamba, and the speaker.

Algebraic Geometry Seminar: Algebraic Geometry Seminar: Dmitry Kaledin - Towards non-commutative Hodge theory
  •   4:00pm - 5:00pm

Speaker:   Dmitry Kaledin

Abstract:  
In non-commutative algebraic geometry, an algebraic variety is
replaced by a DG algebra A, and the role of de Rham cohomology is played by periodic cyclic homology HP(A). It is a standard expectation that all the additional motivic-type structure on de Rham cohomology should also exist in non-commutative generality. There has been a lot of progress on
this in the p-adic situation, but the archimedian case is much more problematic. The missing ingredient is complex conjugation. While a Hodge filtration on periodic cyclic homology exists by definition, we also expect that HP(A) for a good A over C carries a functorial R-structure, and it is not clear at all where it might come from. I am going to present a proposal towards this based on L^2-completed version
of HP. This is still work-in-progress, but the proposal looks viable, so hopefully, this won't be a complete waste of audience's time.
