Richard Wong, RLM 12.166: Galois Extensions of Commutative Ring Spectra
Tuesday, February 12, 2019, 04:00pm - 05:00pm
We will begin by exploring the notion of Galois extensions ofcommutative rings. We will then bring this notion into the worldof ``brave new algebra", and discuss Galois extensions of commutativering spectra. Our primary example will be the $C_2$-Galois extension$KO \to KU$, and we will leverage this to compute the Picardgroup of $KO$.
