The duplicate form of the generalized Gould-Hsu inversions has been obtained by Shi and Zhang. In this paper, we present a simple proof of this duplicate form.
In this paper, we study the existence of solution of a critical fractional equation;we will use a variational approach to find the solution. Firstly, we will fi
In this paper, an overview of the theory of Mössbauer effect is covered, and the main hyperfine interactions parameters which affect the shape of the resul
The phase transitions and the effect on this process of two factors: relative motion and the external influence of the carrier flow (pressure perturbation) are
In this paper, we study the existence of positive solutions for a class of third-order three-point boundary value problem. By employing the fixed point theorem
We consider the oscillation of a class fractional differential equation with Robin and Dirichlet boundary conditions. By generalized Riccati transformation tech
