Meson and Clifford algebras

The aim of this work is to give a characterisation of the associative algebra with unit element that can be written as a quotient of the meson algebra B(M,f) of a free module M with a non-singular symmetric bilinear form f. In particular, to know when an associative algebra with unit element is isomorphic to a meson algebra of a free symmetric bilinear module (M,f).
