Abstract
The algebra - and thus the very Fock space - of free electrons is assumed t o be modified by the interaction induced by phonons. The BCS theory of supe rconductivity is reformulated in a way which allows us to recover all known features by describing within a unique graded algebra both Cooper pairs (w hich turn out to be true bosonic particles) and single electrons with the f eatures of fermions.
