In this paper we prove that a bounded pseudo-differential operator T-sigma:L-p(S-1)- L-p(S-1) for 1 = pinfinity p, is a Separation-Preserving operator and give a formula for its symbols sigma. Using these formulas we give a new representation for the symbol of adjoint and products of two pseudo-differential operators.
