Exact solutions for some non-linear differential equations using complex hyperbolic function methods

Applicable Analysis, 2008
Based on computerized symbolic computation, the coth–csch complex hyperbolic-function method is proposed for the general non-linear equations of mathematical physics in a unified way. In this article, we assume that exact solutions for a given general non-linear equations be the superposition of different powers of the coth-function, csch-function and ...

On complexity of problem of satisfiability for systems of countable-valued functional equations

Russian Mathematics, 2015
The authors prove that the problem of satisfiability for the system of functional equations over the set \(\{ p\}\) belongs to the class \(\prod_1 \) of Kleene-Mostowski arithmetical hierarchy. As a result, they show that the set of all satisfiable systems of functional equations over \(\{ p\}\) is an \(m\)-complete set in the class \(\prod_1 \) of the

Exp-Function Method and Fractional Complex Transform for Space-Time Fractional KP-BBM Equation

Communications in Theoretical Physics, 2017
Summary: In the present article, He's fractional derivative, the ansatz method, the \((G'/G)\)-expansion method, and the exp-function method are used to construct the exact solutions of nonlinear space-time fractional Kadomtsev-Petviashvili-Benjamin-Bona-Mahony (KP-BBM). As a result, different types of exact solutions are obtained.
