"Analytic nc functions"

In this talk, we will discuss higher-order nc functions and in particular, derivatives of arbitrary order. We will show that every locally bounded nc functions is analytic and can locally be expressed as “power series" with multi-linear coefficients, the so-called Taylor-Taylor series.

"Stone duality revisited: hom functors"

Let B be a Boolean algebra and X a Stone space. Today I’ll show how Hom(B,2) naturally has the structure of a Stone space and Hom(X,2) naturally has the structure of a Boolean space. In particular, Hom(Hom(B,2),2) is isomorphic to B.

"Putting the "Homotopy" in Homotopy Type Theory"

In this week's meeting of the Homotopy Type Theory Seminar, we begin by reviewing path induction. We then interpret Martin-Lof type theory in a homotopy-theoretic manner, viewing types as higher groupoids and functions as functors. We also discuss in detail how the notion of a homotopy between paths is related to identity types. Those who did not attend previous meetings are still encouraged to come!

"Disintegration phenomena for planar algebraic vector fields"

In my talk, I will discuss some disintegration phenomena in the specific case of complex polynomial vector fields on the affine plane \mathbb{A}^2_\mathbb{C}.
