Abstract
The structure of the algebra generated by one-electron charge and spin density operators with an appropriately defined convolution product i s investigated in the context of the unitary group approach (UGA) to t he many-electron correlation problem. The new idempotent density opera tors, defined via the unitary group U(n) projection operators, are int roduced and employed to investigate the behavior of charge and spin de nsity operators under the convolution product.
