A New Approach of Morgan-Voyce Polynomial to Solve Three Point Boundary Value Problems

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2021
In this paper, a new procedure is introduced to estimate the solution for the three-point boundary value problem which is instituted on the use of Morgan-Voyce polynomial. In the beginning, Morgan-Voyce polynomial along with their important properties is

Operator equations and Moyal products -- metrics in quasi-hermitian quantum mechanics

, 2005
The Moyal product is used to cast the equation for the metric of a non-hermitian Hamiltonian in the form of a differential equation. For Hamiltonians of the form $p^2+V(ix)$ with $V$ polynomial this is an exact equation.

Fibonacci-like Differential Equations with a Polynomial Non-Homogeneous Part [PDF]

, 1986
We investigate non-homogeneous linear differential equations of the form $x''(t) + x'(t) - x(t) = p(t)$ where $p(t)$ is either a polynomial or a factorial polynomial in $t$.

Integral transformation of Heun's equation and some applications

, 2014
It is known that the Fuchsian differential equation which produces the sixth Painlev\'e equation corresponds to the Fuchsian differential equation with different parameters via Euler's integral transformation, and Heun's equation also corresponds to Heun'
