چکیده

<p style='text-indent:20px;'>In present paper, we deal with the behavior of a solution beyond occurrence wave breaking for modified periodic Coupled Camassa-Holm system. By introducing new set independent and dependent variables, which resolve all singularities due to possible breaking, this evolution system is rewritten as closed semilinear The local existence obtained fixed points contractive transformation. Moreover, formulation allows us continue after gives global conservative where energy conserved almost times. Returning original variables. We finally obtain semigroup solutions, depend continuously on initial data. Additionally, our results repair some gaps in pervious work.</p>

Periodic Conservative Solutions for the Two-component Camassa–holm System

We construct a global continuous semigroup of weak periodic conservative solutions to the two-component Camassa–Holm system, ut − utxx + κux + 3uux − 2uxuxx − uuxxx + ηρρx = 0 and ρt + (uρ)x = 0, for initial data (u, ρ)|t=0 in H1 per ×Lper. It is necessary to augment the system with an associated energy to identify the conservative solution. We study the stability of these periodic solutions by...

Global conservative solutions of the Camassa-Holm equation

This paper develops a new approach in the analysis of the Camassa-Holm equation. By introducing a new set of independent and dependent variables, the equation is transformed into a semilinear system, whose solutions are obtained as fixed points of a contractive transformation. These new variables resolve all singularities due to possible wave breaking. Returning to the original variables, we ob...

Generic Regularity of Conservative Solutions to Camassa-Holm Type Equations

Global Conservative Solutions of the Camassa–holm Equation — a Lagrangian Point of View

Abstract. We show that the Camassa–Holm equation ut −uxxt +3uux −2uxuxx −uuxxx = 0 possesses a global continuous semigroup of weak conservative solutions for initial data u|t=0 in H. The result is obtained by introducing a coordinate transformation into Lagrangian coordinates. To characterize conservative solutions it is necessary to include the energy density given by the positive Radon measur...

Singular solutions of a modified two-component Camassa-Holm equation.

The Camassa-Holm (CH) equation is a well-known integrable equation describing the velocity dynamics of shallow water waves. This equation exhibits spontaneous emergence of singular solutions (peakons) from smooth initial conditions. The CH equation has been recently extended to a two-component integrable system (CH2), which includes both velocity and density variables in the dynamics. Although ...
