Existence and numerical approximation of a one-dimensional Boussinesq system with variable coefficients on a finite interval
Juan Carlos Muñoz Grajales, Deissy Marcela Pizo
In this paper, we investigate the well-posedness of a nonlinear dispersive model with variable coefficients that describes the evolution of surface waves propagating through a one-…

Existence and numerical approximation of solutions of a Schrödinger equation with derivative in the nonlinear term
Juan Carlos Muñoz Grajales, Deissy Marcela Pizo
In this paper, we study a Schrödinger-type equation featuring a derivative in the nonlinear term and incorporating diffusion effects. This type of equation arises in various physi…

An inverse problem for linear system of dispersive equations
Deissy Marcela Pizo, Juan Carlos Muñoz Grajales
This paper addresses the inverse problem of identifying the linear velocity coefficient in a linear system governed by two Benjamin-Bona-Mahony-type equations, which model the disp…
