“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.

"Decentralized Communications Networks"
After a brief introduction to the concept of channel capacity and reliable transmission over noisy environments, we focus on a class of interference channels known as decentralized networks. By definition, these are networks with no central controller or direct coordination among existing parties. We show how separate transmitter-receiver pairs learn about the parameters in the underlying affine system model and discuss fundamental limits of communication in this framework.

"Weak König's Lemma over RCA_0"
Since the addition of Konig's Lemma to RCA_0 presented last time proved to be too strong, we will next investigate the addition of Weak Konig's Lemma to RCA_0. To show that this will have strength strictly between RCA_0 and ACA_0, we will spend some time discussing the PA degrees, including an important application of the Low Basis Theorem.
