Abstract

The equilibrium shapes of nearly spherical phospholipid vesicles were determined taking into account finite elasticity of the membrane and of the enclosed liquid. Using spherical harmonics expansion and the second order approximation, the equilibrium shape of a vesicle was found to be either spherical or quadrupolarly distorted, depending on the volume of the vesicle and the areas of the two leaflets of the membrane in the unstretched state.
