Abstract:
The Euler-Lagrange shape equation and boundary conditions of two-domain vesicles which have different curvature modulus with rotational symmetry are investigated by variational method. Then the numerical solutions of shape equation of two-domain vesicles under definite boundary conditions are obtained through shooting method. The equilibrium shape at different εκ and different line tension coefficient λ are confirmed.The shape change of two-domain vesicles which have different curvature modulus is find at the different εκ and λ.The reason of such phenomenon is bending energy and tension energy of two-domain vesicles competing with each other. The results show that the numerical method is reasonable for study the equilibrium shape of two-domain vesicles, which help for further study of experiment-related problems for two-domain vesicles with different curvature modulus.
