Finite-time relaxation of the solution of a nonlinear pseudoparabolic equation
M. O. Korpusov, A. G. Sveshnikov Faculty of Physics, Moscow State University, Moscow, 119992 Russia
Abstract:
A model equation is considered that describes the relaxation of an initial perturbation in a crystalline semiconductor in the case when its electrical conductivity depends nonlocally on the field.
For certain initial parameters, the effect of finite-time “cooling” is proved to occur. For other parameters, the first term of the long-time asymptotics is found and the remainder of the asymptotic expansion is estimated.
Key words:
nonlinear pseudoparabolic equations, finite-time relaxation, long-time asymptotics of solutions, estimate of asymptotic expansion remainder.
