Mapping properties of regular and strongly degenerate elliptic differential operators in the Besov spaces . The case
Physical analysis of phase transformation of materials consisting from several (both substitutional and interstitial) components, coming from the Onsager extremal thermodynamic principle, leads, from the mathematical point of view, to a system of partial differential equations of evolution type, including certain integral term, with substantial differences in particular phases (, ) and in moving interface of finite thickness (), in whose center the ideal liquid material behaviour can be detected....
