Query: Spectra of translations and Wiener-Hopf operators on Lw^2(R^+)   We study the bounded operators on weighted spaces Lw^2 on R^+ commuting
either with the right translations St or left translations and we establish the
existence of a symbol for these operators. We characterize completely the
spectrum of St. We give also a spectral results for the left translations and
for the bounded operators commuting with the semi-group (St) or with the
semi-group of the left translations.
