Summary. A numerical method is established to solve the problem of minimizing a nonquasiconvex potential energy. Convergence of the method is proved both in the case on its own and in the case when it is combined with a weak boundary condition. Numerical examples are given to show that the method, especially when applied together with a continuation method and some other numerical techniques, is not...
Summary. A numerical method, with truncation methods as a special case, for computing singular minimizers in variational problems is described. It is proved that the method can avoid Lavrentiev phenomenon and detect singular minimizers. The convergence of the method is also established. Numerical results on a 2-D problem are given.
