Abstract: Abstract In this chapter the reader is supposed to be acquainted with the algebraic structure of an n-dimensional abstract vector space $$E_n$$ E n . We here show how to generate many other algebraic structures starting from a vector space. We begin by defining the dual vector space, the contravariant, covariant, and mixed tensors. We then collect all these new entities in the global structure of tensor algebra $$T(E_n)$$ T ( E n ) on $$E_n$$ E n . Finally, the exterior algebra, that is the subalgebra of $$T(E_n)$$ T ( E n ) of skew-symmetric covariant tensors, and its geometric meaning are analyzed.
