Andrew Jordan reviews Peter Woit's Quantum Theory, Groups and Representations and finds much to admire.
I also don’t think I’ve ever come across the journal Inference before, but it looks quite nice in terms of content and editorial.
Retired UCI math professor Steven Roman has just started making a series of Group Theory lectures on YouTube.
He hopes to eventually also offer lectures on ring theory, fields, vector spaces, and module theory in the near future.
“contains significant amounts of material not well-explained elsewhere.”He expects to finish up the diagrams and publish it next year some time, potentially through Springer.
I finally have finished a draft version of the book that I’ve been working on for the past four years or so. This version will remain freely available on my website here. The plan is to get professional illustrations done and have the book published by Springer, presumably appearing in print sometime next year. By now it’s too late for any significant changes, but comments, especially corrections and typos, are welcome.
At this point I’m very happy with how the book has turned out, since I think it provides a valuable point of view on the relation between quantum mechanics and mathematics, and contains significant amounts of material not well-explained elsewhere.

“Why should we want to know about representations over rings that are not fields of characteristic zero? It is because they arise in many parts of mathematics. Group representations appear any time we have a group of symmetries where there is some linear structure present, over some commutative ring. That ring need not be a field of characteristic zero.
Here are some examples.

- In the theory of error-correcting codes many important codes have a non-trivial symmetry group and are vector spaces over a finite field, thereby providing a representation of the group over that field.”
