"Topics in Algebraic Topology" is a course that I took several times at KU, the goal being to give a presentation about a certain topic in algebraic topology (broadly speaking), usually based on one or several papers (but not always). Here are the notes I wrote for the class:
On the paper Universality of multiplicative infinite loop space machines (Gepner-Groth-Nikolaus) - in this case, essentially a summary of the paper : Universality of multiplicative infinite loop space machines
An introduction to chromatic homotopy theory, based on Lurie's lecture notes on the topic - it's meant to be slightly less technical than those notes, and more approachable for a first attempt: An overview of chromatic homotopy theory
