In Section 6.4 we gave an intuitive introduction to the concept of Grassmann algebra as an associative algebra of dimension constructed from a vector space of dimension . Certain difficulties, particularly those relating to the definition of exterior product, were cleared up by the more formal approach to the subject in Section 7.1. In this chapter we propose a definition of Grassmann algebra entirely of tensors [1–5]. This presentation has a more ‘concrete’constructive character, and to distinguish it from the previous treatments we will use the term exterior algebra over to describe it from here on.
