About gauge equivalent of the generalized Landau-Lifshitz equation
Вестник КазНУ. Серия математика, механика, информатика, 2017 In mathematics an inverse scattering transformation is a method for solving some nonlinear equations with partial derivatives. Discovering of the method became one of the crucial events in mathematical physics in the last 40 years [1]–[6].

Advanced Functional Materials, EarlyView.Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

On the Polar Equations for Linear Systems and Related Nonlinear Matrix Differential Equations [PDF]
Transactions of the American Mathematical Society, 1965 0. Introduction. This paper is devoted to laying the groundwork for a theory of matrix differential equations and associated linear systems. The fundamental problem is that of characterizing the solutions of general linear systems from the coefficient matrices themselves.
