Tensor Spaces - Seminar Resources |
||
The material below presents the basic theory of tensor products over vector spaces at the level of beginning graduate students. This material was used by me in seminars in combinatorics (UCSD, Mathematics and CSE) where tensor spaces were used. W1 contains the most basic material and was presented first, followed by M2 (plus a review of M1 which is an alternative to W1). The remaining articles (M3, M4, M5, M6) are more specialized, useful for topics in algebraic combinatorics.* |

Tensor spaces - the basics | ||
W1: This material defines tensor products of vector spaces, develops the critical notational conventions for this subject, and contains the discrete mathematics background material. Section topics: (1) Introduction; (2) Basic multilinear algebra; (3)Tensor products of vector spaces; (4)Tensor products of matrices; (5) Inner products on tensor spaces; (6) Direct sums and tensor products; (7) Basic concepts and notation.

* The seminar notes by Professor Marcus (my thesis advisor) were provided to me as they were developed. M1, M2, M3 were combined by the author and published by Marcel Dekker in book form as Finite Dimensional Linear Algebra, Part I, 1973 (out of print). M4, M5, M6 were expanded and became part of Finite Dimensional Linear Algebra, Part II, 1975, Marcel Dekker (out of print). The individual chapter indices to these seminar notes were provided by me for the convenience of my students. |

Linear Algebra Review: A review of linear algebra concepts was found to be very helpful in getting students "on the same page" for the seminar on tensor spaces. The following handout evolved from this need: |
