In this work we show the existence existence and uniqueness of traveling waves for diffusive-dispersive conservation laws with flux function in $C^{1}(mathbb{R})$, by using phase plane analysis. Also we estimate the domain of attraction of the equili

We consider the initial value problem (IVP) associated to a coupled system of Kawahara/KdV type equations. We prove the well-posedness results for given data in a Gevrey spaces. The proof relies on estimates in space-time norms adapted to the linear

In this paper we extend to Kawahara type equations a uniqueness result obtained by C. E. Kenig, G. Ponce, and L. Vega for KdV type equations. We prove that, under certain decay's conditions, the null solution is the unique solution.

In this paper the Green’s function method and results about fixed point are used to get existence results on periodic traveling wave solution for non-homogeneous problems of generalized versions of the BBM and KdVB equations. It is shown through th

We consider conservation laws with discontinuous flux, which are regularized with generalized BBM-Burgers equations. We study the convergence of one sequence of solutions of these equations for one solution of the associated conservation law. In the

We study the global existence of solutions for certain equations of the form as δ > 0 and γ n > 0, n = 1, …, N approach zero, and f is a sufficiently smooth function satisfying certain appropriate assumptions. We consider solutions of hyperbolic

A notion of entropy quasisolution is introduced for the Euler equations of isothermal gas flows. Such a solution is obtained by means of nonlinear parabolic approximation with a small parameter ε. Compensated compactness argument is applied to justi

We consider solutions of hyperbolic conservation laws regularized with vanishing diffusion and dispersion terms. Following a pioneering work by Schonbek, we establish the convergence of the regularized solutions toward discontinuous solutions of the
