Klyatskin, in Dynamics of Stochastic Systems, However, only a few dynamic systems lend themselves to analysis yielding solutions in a general form. It proved to be more efficient to use an asymptotic method where the statistical characteristics of dynamic problem solutions are expanded in powers of a small parameter which is essentially a ratio of the random impact's correlation   1.

Introduction. Semilinear stochastic wave equations arise as mathe-matical models to describe nonlinear vibration or wave propagation in a randomly excited continuous medium. To be specific, the equation may take the form ∂2 () t u(x,t)=c2∆u−2α∂tu(x,t)+f(u)+σ(u)W˙ (x,t) in a bounded domain D in Rd, subject to some homogeneous This book gives introductory chapters on the classical basic and standard methods for asymptotic analysis, such as Watson's lemma, Laplace's method, the saddle point and steepest descent methods In the present book four classes of problems are considered: the Dirichlet problem with a small parameter in higher derivatives for differential equations and systems - the averaging principle for stochastic processes and PDE's - homogenization in PDE's and in stochastic processes - wave front propagation for semilinear differential equations  › Birkhäuser › Applied Mathematics.
