ResumoWe introduce the new concept of pseudo-(normed Q) algebra. This is a generalisation of the notion of pseudo-complete algebra. Using it we study the Allan-Waelbroeck spectrum σA (x) and the extended spectrum Σ(x), given by W. Żelazko, for x in a unital locally convex algebra. In particular, we compare these two spectra.
