Abstract:
We have previously introduced the notion of non-commutative phase space (algebra)
associated to any associative algebra, defined over a field. The purpose of the
present paper is to prove that this construction is useful in non-commutative
deformation theory for the construction of the versal family of finite families
of modules. In particular, we obtain a much better understanding of the
obstruction calculus, that is, of the Massey products.
