We introduce many examples, and study the fundamental notions of submodules, factor modules and module homomorphisms. For group algebras, and for path algebras of quivers we make the correspondence between modules and representations explicit.补角 发表于 2025-3-27 18:17:02

Robert G. Boatright,Molly Brigid McGrathdean types. As for some background, we give a short account of root systems as they occur in Lie theory, and we show that the set of roots, as defined in the setting of representation theory, is a root system in this sense. We finish with an informal account of Morita equivalence.apropos 发表于 2025-3-28 10:17:35
