Computability Learning Seminarr

Joey Lakerdas-Gayle, University of Waterloo

K-triviality

We will introduce K-trivial sets following Chapter 11 of Downey & Hirschfeldt. We will prove some basic factssuch as the Solovay-Zambella Theorem that there exist noncomputable K-trivial c.e. sets.

Updates on flows of geometric structures

Aiming at a public with interests among Riemannian and complex geometry, Lie groups and parabolic PDEs, Iwill recall some results towards a general analytical theory for flows of H-structures, obtained with Fadel,Loubeau and Moreno. Then, as a concrete example, I will present some recent progress on SU(2)-flows on 4-manifolds, initiating a classification programme of ‘parabolic’ flows, based on a representation-theoretic methodoriginally due to Bryant in the context of G2 geometry, obtained with Fowdar.
