“Introduction to Reverse Mathematics (continued)”

We finish characterizing the ω−modelsofRCA0. If time helps, we continue doing the same for ACA0.  If time permits, Michael Deveau will do the same for ACA_0.

“Approximate Groups: VII”

We continue to follow van den Dries Seminaire Bourbaki article entitled Approximate Groups [after Hrushovski, and Breuillard, Green, Tao]. The subject involves the interaction of additive combinatorics and model theory.

''Uniqueness theorems for graph algebras and applications”

This week we will discuss uniqueness of graph algebras up to the existence of a gauge circle action. We will then use this to prove that for graphs with no sources, the graph algebra of the graph is *-isomorphic to the graph algebra of the dual of that graph.

“Cubing Finite Taylor Algebras”

I will provide the details showing how finite idempotent Taylor algebras can be character- ized by the hereditary existence of cubed elements. There is a corresponding notion of cube absorption which can be described as Few Subpowers and Absorption Theory in a blender. If there is time, I would like to pose a problem here.

“Approximate Groups: VIII”

We continue to follow van den Dries Seminaire Bourbaki article entitled Approximate Groups [after Hrushovski, and Breuillard, Green, Tao]. The subject involves the interaction of additive combinatorics and model theory.
