in the present study an alternative model allows the extension of the debye-hückel theory (dht) considering time dependence explicitly. from the electro-quasistatic approach (eqs) done in earlier studies time dependent potentials are suitable to describe several phenomena especially conducting media as well as the behaviour of charged particles in arbitrary solutions acting as electrolytes.this...

in this paper, the exp-function method, with the aid of a symbolic computation system such as maple, is applied to the (2+1) -dimensional calogero bogoyavlanskii schiff equation. exact and explicit generalized solitary solutions are obtained in more general forms. the free parameters can be determined by initial or boundary conditions. the method is straightforward and concise, and its applicat...

This paper is concerned with the inverse spectral problem for third-order differential equation distribution coefficient. The consists in recovery of expression coefficients from data two boundary value problems separated conditions. For this problem, we solve most fundamental question theory about necessary and sufficient conditions solvability. In addition, prove local solvability stability p...
