Phase portraits and new exact traveling wave solutions of the (2+1)-dimensional Hirota system

Autor: Gaukhar Shaikhova, Bayan Kutum, Arailym Syzdykova

Publikováno v: Results in Physics, Vol 55, Iss , Pp 107173- (2023)

In this paper, we investigate the (2+1)-dimensional Hirota system of equations, which is essential for modeling physical events since it contains the NLS equation and the cmKdV equation. We apply the Jacobi elliptic function method to obtain new resu

Periodic traveling wave, bright and dark soliton solutions of the (2+1)-dimensional complex modified Korteweg-de Vries system of equations by using three different methods

Autor: Gaukhar Shaikhova, Bayan Kutum, Ratbay Myrzakulov

Publikováno v: AIMS Mathematics, Vol 7, Iss 10, Pp 18948-18970 (2022)

In this paper, the (2+1)-dimensional complex modified Korteweg-de Vries (cmKdV) equations are studied using the sine-cosine method, the tanh-coth method, and the Kudryashov method. As a result, analytical solutions in the form of dark solitons, brigh
