Title:
A generalised six squares theorem applied to PI algebras: Abstract:
The theories of superalgebras and P.I. algebras lead to a natural Z_2 graded extension of the integers. For these generalised integers a "six-generalised-squares" theorem can be proven, which can be considered as a Z_2 graded analogue of the classical "four squares" theorem for the natural numbers. This theorem has applications to P.I. algebras.
