If you are a UConn graduate student planning to take the prelims, here are my experiences with the ones I took.
Measure Theory: Here are some rough notes, and solutions to some past prelim problems. It was very helpful for me to keep track of proof strategies for different classes of problems, for ex. those concerning Hölder/Minkowski inequalities.
Topology: Some notes. Again, while they are not complete, I hope they serve as a helpful guide in what they do contain (ideas/proof strategies in connectedness, computing fundamental groups with more rigor, and some stuff on universal properties of product, quotient topologies, etc.)
Complex Analysis: Here are my notes. These are much more complete (excluding details on integration w/ residues), and are a summary version of Dr. Chousionis' excellent notes on the subject.
