Abstrakt: It is shown in this paper that the existing theories of the form fluctuations of quasispherical lipid vesicle give a too mean stretching energy of its membrane. A more precise theory taking into account the area conservation of the membrane is proposed. The relation between the amplitudes of the form fluctuations and the curvature elastic modulus of the membrane is obtained numerically by means of a suitable Monte Carlo simulation.
