"A twisted nonabelian Hodge correspondence"
The classical nonabelian Hodge correspondence establishes an equivalence between certain categories of flat bundles and Higgs bundles on smooth projective varieties. I will describe an extension of this result to twisted vector bundles. No prior knowledge of the above topics will be assumed: come one, come all! There will be pancakes too.

“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.

“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.

''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.

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.
