We study the limit properties of solutions to one class of systems of differential equations as the number of equations and some parameters tend to infinity. We establish a close connection between solutions to these systems and differential equations with retarded argument. Our convergence theorems provide a new method for approximation of solutions to nonlinear differential equations with retarded argument.Original Russian Text Copyright © 2005 Demidenko G.

The coefficients of thermal expansion, lattice constant, and magnetization of anion-substituted MnSe1 - xTex chalcogenides were measured upon cooling in zero and nonzero magnetic fields in the temperature range 4.2–600 K. Resistivity as a function of magnetic field up to 1 T was measured. The dynamic properties of the materials were studied by the ESR method. Magnetoresistance and temperature hysteresis were found in MnSe1 - xTex solid solutions. 相似文献

The structural, magnetic, electrical, and thermoelectric properties of GdXMn1?XS () solid solutions synthesized for the first time on the basis of -MnS have been studied experimentally in the temperature range 77–1000 K in magnetic fields up to 10 kOe. The synthesized samples are antiferromagnetic semiconductors with an NaCl-type cubic lattice typical of -MnS. Both concentration () and temperature () metal–insulator phase transitions have been observed. The concentration metal–insulator transition is accompanied by a decrease in resistivity and thermopower by twelve and two orders of magnitude, respectively, with the change in conductivity from p-type to n-type. 相似文献

Under study is a systemof linear differential equations of neutral type with several delays of the argument. We obtain the conditions on the matrix coefficients of the system under which all solutions decrease with an exponential rate at infinity. Using some functionals of Lyapunov-Krasovskii type, the uniform estimates of solutions are established. 相似文献
