Math Graduate Student Seminar

Hello, reader. I want to play a game. Here is what happens if you lose: I had a winning strategy all along. We will fix a set A of infinite strings of natural numbers. Then you pick a number, then I choose one, then you pick again, and so on. Your challenge: ensure the final string we create is in A.

We discuss the thrilling topological games that people play, the cunning strategies involved, and the shocking consequences one may derive in descriptive set theory. Aptness of adjectives in the previous sentence not guaranteed.
