Hello, This thread is about the two books by Naber: https://www.amazon.com/Topology-Geometry-Gauge-fields-Foundations/dp/1461426820 https://www.amazon.com/Topology-Geometry-Gauge-Fields-Interactions/dp/0387989471 The topics in this book seem excellent. They are standard mathematical topics such as homotopy, homology, bundles, characteristic classes, etc. But unlike math books, the links to physics are clearly displayed. Nevertheless, the book does remain mathematically rigorous. If anybody here went through this text, what did you think about it? And did you find the exercises suitable enough to make you understand the topic (versus superficial exercises). Does anybody know similar books to this one which are good?
