In this work, we present a new type of fractional derivatives (FD) involving exponential
cotangent function in their kernels called Riemann–Liouville D σ, γ and Caputo cotangent …

In this paper, we combine the finite integration method (FIM) with the technique of fictitious
points to solve high order partial differential equations (HOPDEs). Two type of fictitious finite …

The purpose of this paper is to obtain numerical solutions of fractional interval optimal
control problems. To do so, first, we obtain a system of fractional interval differential …

This article presents a novel numerical approach to the solution of the nonlinear Kawahara
equation. The desired approximations are obtained from the combination of Dickson …

This thesis aims to present a straightforward, convergent, and readily applicable numerical
method for computing approximate solutions to linear two-dimensional first-order and …

Haar wavelet-based numerical algorithms have recently been developed for various
mathematical problems, including optimal control problems. However, no numerical …
