Comparison of two methods of consideration of surface energy in problems on phase transitions in large force fields

Two methods of consideration of surface energy were compared by the author in the case of variational problems on phase transitions in continuous-medium mechanics and problems on phase transitions in thermoelasticity. In this paper, these methods are compared for problems on phase transitions in large force fields. Bibliography: 5 titles. Translated fromProblemy Matematicheskogo Analiza, No. 19, 1999, pp. 182–192.
