Hi all, What is a good introductory book on tensor products and tensor algebras? For motivation, I have found Tom Coates's lecture note to be quite helpful, but I would like to do see some examples and do problems to understand it more thoroughly. My main aim is to be able to construct Clifford algebras by taking quotient of tensor algebras. I have become able to construct Clifford algebras using exterior products (the way Clifford did it) and quadratic spaces. But understanding tensor algebras and using them to create Clifford algebras seems impregnable. Thanks.
