Bright and dark solitary wave soliton solutions for the generalized higher order nonlinear Schrödinger equation and its stability

open access: yesResults in Physics, 2017
The higher order nonlinear Schrödinger (NLS) equation describes ultra-short pluse propagation in optical fibres. By using the amplitude ansatz method, we derive the exact bright, dark and bright-dark solitary wave soliton solutions of the generalized ...

On similarity solutions to (2+1)-dispersive long-wave equations

open access: yesJournal of Ocean Engineering and Science, 2023
This work is devoted to get a new family of analytical solutions of the (2+1)-coupled dispersive long wave equations propagating in an infinitely long channel with constant depth, and can be observed in an open sea or in wide channels.

Entire solutions of certain fourth order elliptic problems and related inequalities

open access: yesAdvances in Nonlinear Analysis, 2022
We study distributional solutions of semilinear biharmonic equations of the type Δ2u+f(u)=0 onℝN,{\Delta ^2}u + f(u) = 0\quad on\;{{\mathbb R} ^N}, where f is a continuous function satisfying f (t)t ≥ c |t|q+1 for all t ∈ ℝ with c > 0 and q > 1.

A comparison principle for nonlinear heat Rockland operators on graded groups

open access: yesBulletin of the London Mathematical Society, Volume 50, Issue 5, Page 753-758, October 2018., 2018
Abstract In this note we show a comparison principle for nonlinear heat Rockland operators on graded groups. We give a simple proof for it using purely algebraic relations. As an application of the established comparison principle we prove the global in t‐boundedness of solutions for a class of nonlinear equations for the heat p‐sub‐Laplacian on ...

Solutions of stationary McKean–Vlasov equation on a high-dimensional sphere and other Riemannian manifolds

open access: yesAdvances in Nonlinear Analysis
We study stationary solutions of McKean–Vlasov equation on a high-dimensional sphere and other compact Riemannian manifolds. We extend the equivalence of the energetic problem formulation to the manifold setting and characterize critical points of the ...

Unveiling pure-quartic solitons for the generalized nonlinear Schrödinger equation with Kerr nonlinearity using the modified extended direct algebraic method

open access: yesNonlinear Engineering
Pure-quartic solitons have recently gained increasing interest due to their unique dispersion landscape, where pulse evolution is governed solely by fourth-order dispersion.
