Abstract
The thermal fluctuations of nearly spherical micelles are considered. The viscosity and compressibility of the surfactant
layer and of the bulk fluids are taken into account as well as the bending energy. The dynamical equations for surface and
bulk variables are the linearized hydrodynamic equations with random sources of stresses. Employing the fluctuation-dissipation
theorem the spectral densities of fluctuations related with surface excitations were derived. The behaviour of the dynamical
structure factor
is discussed for various droplet parameters.
