Unitary Quantum Symmetries Lite
I am in the process of compiling my notes from 3 topics courses at OSU from 2018 (Quantum Algebra), 2021 (Topological Phases of Matter), and 2023 (Higher Linear Algebra) into a book with Giovanni Ferrer and Kyle Kawagoe.
The book has 3 parts. Each part discusses objects, their endomorphisms, a weaker version of equivalence, some important examples, and applications.

Chapters 3-4
Drafts of Chapters 3-4 posted. Chapter 3 is still very much a work in progress. We may be able to simplify the exposition -- we are in the process of balancing operator algebraic techniques with the (semi)simplicity of the various unitary versions of representation theory.

Up and running
Drafts of Chapters 1-2 posted. More updates coming soon (in geological time).
