Vectors - declaration of vectors

Vectors[v1, v2, ..., vi, ..., vn]
allows one to declare vectors.
  • vi - vector identivier.
  • In the Atlas package any identifier is treated as 0-form i.e. as non-constant scalar (if it not declared as constant, p-form, tensor etc. (see Types).
  • One can declare indexed vectors e.g. j is treated as a set of vectors 1, 2, ..j.
