摘要:The topological method of investigation of regularities at phase transitions in ferroelectric crystals and the nonlinear phenomena, based on representations about cellular complexes of system of special points of non-equilibrium thermodynamic potential have been stated. Full set ...

摘要:By the method of Landau thermodynamics a possibility of realization of phase transitions characterized by a vector of polarization and a tensor of deformation in crystals of all classes of point group of symmetry is investigated. The analysis is carried out by drawing up of the l...

摘要:Abstract(#br)A new criterion for global smooth equivalence of a pair of key functions corresponding to a smooth functional in the calculus of variations for a given pair of finite-dimensional reduction schemes is established. The statement is presented in abstract form (we consid...

摘要:Abstract(#br)In this paper we construct a procedure of approximate calculation and analysis of branches of bifurcating solutions to a periodic variational problem. The goal of the work is a study of bifurcation of cycles in dynamic systems in cases of double resonances 1: 2:...
