Abstract:The Cauchy problem of higher-dimensionar linear partial differential systems with variable coefficients is studied by taking M-matrix~[1] as a tool. A series of algebraic criteria (M-criteria) is obtained for the consistent suitability of the Cauchy probl

Abstract:The site-diagonal and site-off-diagonal electron-lattice coupling in quasi-one-dimensional halogen-bridged mixed-valence metal complexes (HMMC's) are investigated. The effects of off-diagonal coupling on polaronic binding energy are firstly calculated by

Abstract:In this paper, we investigate the continuity of a Q_1Q_2-mapping and the convergence of a net of quasi-atoms. We also give a unified treatment to the continuity and the convergence in both point-set topology and fuzzy topology.
