 MULTILINEAR ALGEBRA TOP
 From 1965 to 1972 my research focused on applications of multilinear algebra to combinatorics. After that, I worked mostly on algorithmic combinatorics. The interplay between combinatorics and multilinear algebra is fascinating. Below we attempt to look back at that subject, review some relevant background material, and address some unresolved issues.
 The basic lecture notes for this topic were provided by Professor Marvin Marcus from his seminar at UCSB 1965-70. Dr. Tony Trojanowski provided the corrigenda.
 (1) Tensor Spaces* (3) Tensor Algebras (2) Tensor Transformations
 (4) Grassmann Algebras (5) Clifford Algebras (6) Representation Theory
 These lecture notes were extended and later published as Finite Dimensional Multilinear Algebra, Part I (1973) and Part II (1975) (both out of print): 14 and 18
 * Depending on emphasis, we replace (1) Tensor Spaces, with the following:
 For the benefit of first year graduate students, I wrote a review of linear algebra which emphasized canonical forms as a training ground for notational skills and proof techniques. This review has been redone in LaTeX with new material added. I wish to thank Dr. Tony Trojanowski and Professor Derij Grinberg for a careful reading and numerous corrections.and helpful suggestions.
 Matrix Canonical Forms
 notational skills and proof techniques
 During the 1963-64 academic year, Professor Carl Loewner, Stanford University, visited the Department of Mathematics, UCSB. Professor Loewner asked if Marcus's recent work on inequalities for permanents could be used to derive certain inequalites studied by I. Schur in 1918. We present here the results of that discussion.

 The following article discusses a generalization of the Laplace expansion theorem that possibly relates to future topics in multilinear algebra.
