There are longstanding notions of "higher groups" in algebraic topology, and we will discuss some of them as part of an effort to interpret constructions described in the preceding talks. Key references include Freed's overview https://arxiv.org/abs/2212.00195 and the systematic treatment https://arxiv.org/abs/2209.07471 of Freed-Moore-Teleman.
