Abstract. The elsect of electrostatic interactions on
membrane undulations is examined.
We consider a
mixed membrane consisting of neutral and charged amphiphiles in an aqueous
solution. In general, this system may exhibit a
non-uniform surface charge density. Two limiting
cases are
distinguished: quenched surface-charge distribution; and annealed inplane distribution
which is coupled to an
undulation mode. For the former case
the electrostatic free energy of an
