An initial–boundary value problem for the Maxwell equations
Journal of Differential Equations, 2010 In this paper, by using methods from complex analysis and quaternionic analysis, we investigate an initial–boundary value problem for the Maxwell equations and obtain the general solutions and solvable conditions of the problem respectively in different ...

Bounds for Initial Value Problems
Journal of Applied Mechanics, 1973A new method has been developed for finding rigorous upper and lower bounds to the solution of a wide class of initial value problems. The method is applicable to initial value problems of the following type: x(¨t)+f(t,x,x)˙=0,x(0)=X0,x(˙0)=V0, where f is continuous with continuous first derivatives, Lipschitzian, and ∂f/∂x ≥ 0.

Summary: The Boussinesq approximation, where the viscosity depends polynomially on the shear rate, finds frequent use in geological practice. In this paper, we consider the periodic initial value problem and initial value problem for this modified Boussinesq approximation with the viscous part of the stress tensor \(\tau^v=\tau ({\mathbf e})-2 \mu_1 ...

Initial-Value Problems for ODE
2012The ability to reliably solve initial-value problems for ordinary differential equations is essential in order to understand the evolution of dynamical systems. In this chapter we deal with methods of advancing the given initial state of a system to later times, explaining clearly the role of stiffness, local discretization and round-off errors, and ...

Rapidly Forced Initial Value Problems
SIAM Journal on Applied Mathematics, 1993The Cauchy problem for the evolution equation of the type \(u_ t + u_{xx} = f(x,t/ \varepsilon)\), \(t>0\), \(x \in \mathbb{R}^ 1\), with smooth initial function is considered. The function \(f(x, \tau)\) is periodic in \(\tau\). An asymptotic expansion of the solution as \(\varepsilon\to 0\) is constructed in the form of the \(\varepsilon\)-power ...
