Rational and semi-rational solutions to the Mel’nikov equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
We investigate rational and semi-rational solutions to the (2+1)-dimension Mel’nikov equation based on the Hirota bilinear method and the long wave limit approach.

Stability Analysis of the Rational Solutions, Periodic Cross-Rational Solutions, Rational Kink Cross-Solutions, and Homoclinic Breather Solutions to the KdV Dynamical Equation with Constant Coefficients and Their Applications

open access: yesMathematics, 2023
We explore various analytical rational solutions with symbolic computation using the ansatz transformation functions. We gain a variety of rational solutions such as M-shaped rational solutions (MSRs), periodic cross-rationals (PCRs), multi-wave ...

Rational general solutions of planar rational systems of autonomous ODEs

open access: yesJournal of Symbolic Computation, 2011
In this paper, we provide an algorithm to compute explicit rational solutions of a rational system of autonomous ordinary differential equations (ODEs) from its rational invariant algebraic curves. The method is based on the proper rational parametrization of these curves and the fact that by linear reparametrizations, we can find the rational ...

Generalized Rationing Problems and Solutions [PDF]

open access: yesSSRN Electronic Journal, 2015
An extension of the standard rationing model is introduced. Agents are not only identified by their respective claims on some amount of a scarce resource, but also by some exogenous ex-ante conditions (initial stock of resource or net worth of agents, for instance), different from claims.

Multi-Parametric Families of Real and Non Singular Solutions of the Kadomtsev-Petviasvili I Equation

open access: yesUniversal Journal of Mathematics and Applications, 2021
Multi-parametric solutions to the Kadomtsev-Petviashvili equation (KPI) in terms of Fredholm determinants are constructed in function of exponentials. A representation of these solutions as a quotient of wronskians of order $2N$ in terms of trigonometric
