K1 of a C*-algebra”

Having defined K0 of a C*-algebra, we now define K1 as well as provide examples and basic properties.

“Ramsey’s Theorem”

We have seen with Sam two proofs of Ramsey’s Theorem. This time we give a third proof of that uses Konig’s Lemma but can be carried out in RCA0.

“Diophantine equations in the primes”

In their paper ”Diophantine equations in the primes”, Cook and Magyar give a condition for a system of polynomials to be soluble in primes via the Hardy-Littlewood circle method. I would like to describe their method.

“Bundles over Complex Tori, Continued”

I will tie up some loose ends on the classification of vector bundles on elliptic curves from last time and discuss some of Atiyah’s techniques in the classification. After that, I will comment on the progress made on classifying vector bundles over higher dimensional tori.
