deKerf. The asymptotic behavior of the solution u(x, t) of the Korteweg‐deVries equation ut + uux + uxxx = 0 is investigated for the class of problems where the initial data does not give rise to an.

manner, by considering series expansions of solutions of perturbed mathe-matical programs, and 3. the Puiseux series is the natural mathematical object for studying the asymptotic behaviour of a very large class of perturbed mathematical programming problems. Concerning the ﬁrst of the above claims it is sufﬁcient to note that in.

These formulae yield the conclusion that the dispersive nature of the linearized Korteweg-de Vries equation (in the case of the Cauchy problem) is preserved asymptotically for some perturbation terms in the case of mixed initial-boundary value problems too, when the small parameter goes to zero taking some explicitly specified discrete values.

We describe a set of initial conditions for which the Cauchy problem for a singularly perturbed Korteweg–de-Vries equation with variable coefficients has an asymptotic two-phase solitonlike. tions, but perturbation theory and asymptotic analysis apply to a broad class of problems. In some cases, we may have an explicit expression for x", such as an integral representation, and want to obtain its behavior in the limit "!0.

The Korteweg–de Vries equation \[ u_t + uu_x + u_{xxx} = 0\] is a nonlinear partial differential equation arising in the study of a number of different physical systems, e.g., water waves, plasma physics, anharmonic lattices, and elastic rods.

We propose an algorithm for the construction of asymptotic m-phase soliton-type solutions of a singularly perturbed Korteweg–de Vries equation with variable coefficients and establish the accuracy with which the main term asymptotically satisfies the considered equation.

Beneficial to both beginning students and researchers, Asymptotic Analysis and Perturbation Theory immediately introduces asymptotic notation and then applies this tool to familiar problems, including limits, inverse functions, and integrals.

Suitable for those who have completed the standard calculus sequence, the book assumes no prior knowledge of differential s: 3.

() was first derived in Camassa and Holm () by using asymptotic expansions directly in the Hamiltonian for Euler's equations governing inviscid incompressible flow in the shallow water regime.

It was thereby shown to be bi. These initial value problems, and terminal value problems are singularly perturbed problems and therefore fitted mesh method (Shishkin mesh) are used to solve these problems.

Since the asymptotic expansion approximation is used and the boundary value problem is converted into initial value problems and terminal value problems, therefore the method is called Asymptotic initial value method (AIVM). In general solving an initial value problem.

For a spe-cial case = 0, we present the asymptotic formula of the solution to the ex-tended modi ed Korteweg-de Vries equation in region P= f(x;t) 2R2j0 Korteweg-de Vries. On the basis of the inverse scattering transformation, the Cauchy problem of the coupled modified Korteweg–de Vries equation is transformed to a 3 × 3 matrix Riemann–Hilbert problem.

Two distinct factorizations of the jump matrix for the Riemann–Hilbert problem and a decomposition of the vector-valued spectral function are deduced.

Abstract: We investigate an integrable extended modified Korteweg-de Vries equation on the line with the initial value belonging to the Schwartz space. By performing the nonlinear steepest descent analysis of an associated matrix Riemann--Hilbert problem, we obtain the explicit leading-order asymptotics of the solution of this initial value.
