Key words: galaxies: bulges – galaxies: elliptical and lenticular, cD – galaxies: structure – ISM: dust, extinction – galaxies: evolution– galaxies: fundamentalparameters 1 INTRODUCTION Bulges, traditionally defined as the excess of light above the in-ner extrapolation of discs and/or bars, were for a long time thought Two examples illustrate the propagation of instability modes under quasi-static, steady-state conditions. The first is the inflation of a long cylindrical party balloon in which a bulge propagates down the length of the balloon. The second is the collapse of a long pipe under external pressure as a result of buckle propagation.
