Abstract
Soliton-like elementary excitations in bistable systems, whose energie s of different equilibrium states are not equal, are considered. Parti cular physical systems described by a common Hamiltonian are discussed in the framework of proposed approach. The analysis of the continuum equation of motion demonstrates the existence in such systems both of the nontopological solitons connected with energy transfer and topolog ical solitons describing the transitions between different states (sta te transfer). Computer simulation data are compared with solutions of analytical models.
