asymptotic methods and new developments. Particular attention is paid throughout the …

This paper outlines a detailed study of some relatively new techniques which are originated
by He for solving diversified nonlinear problems of physical nature. In particular, we will …

According to the report presented by the World Health Organization, a new member of
viruses, namely, coronavirus, shortly 2019-nCoV, which arised in Wuhan, China, on January …

Theoretical and numerical studies of fractional conformable stochastic integrodifferential
equations are introduced in this study. Herein, to emphasize the solution's existence, we …

We introduce the rudiments of fractional calculus and the consequent applications of the
Sumudu transform on fractional derivatives. Once this connection is firmly established in the …

In this article, linear and nonlinear boundary value problems for fourth-order fractional
integro-differential equations are solved by variational iteration method and homotopy …

In this study, the homotopy perturbation method proposed by Ji-Huan He is applied to solve
both linear and nonlinear boundary value problems for fourth-order integro-differential …

In this paper, a novel technique is being formulated for the numerical solution of integral
equations (IEs) as well as integro-differential equations (IDEs) of first and higher orders. The …

This paper applies He's variational iteration method for solving two systems of Volterra
integro-differential equations. The solution process is illustrated and various physically …

In this work, a system of two nonlinear integro-differential equations which arises in biology
is considered and the well-known variational iteration method is implemented for finding the …
