On a paper of Peng and Wu, part 1
I will discuss the paper of Peng and Wu `A Lindelof group with non-Lindelof Square'. I will focus on the oscillation results and the projection function. If time and patience permits, I will discuss some (unmotivated) slight strengthenings of their results in the partition calculus.
