An Orthogonal Polynomial Solution to the Confluent-Type Heun’s Differential Equation

Mathematics
In this work, we present both analytical and numerical solutions to a seven-parameter confluent Heun-type differential equation. This second-order linear differential equation features three singularities: two regular singularities and one irregular ...

Analytic Solutions of a Second-Order Functional Differential Equation with a State Derivative Dependent Delay

International Journal of Mathematics and Mathematical Sciences, 2015
We investigate an analytic solution of the second-order differential equation with a state derivative dependent delay of the form x″(z)=x(p(z)+bx′(z)). Considering a convergent power series g(z) of an auxiliary equation γ2g″(γz)g′(z)=[g(γ2z)-p(g(γz))]γg′(

On the Polynomial Solution of Divided-Difference Equations of the Hypergeometric Type on Nonuniform Lattices

Axioms, 2019
In this paper, we provide a formal proof of the existence of a polynomial solution of fixed degree for a second-order divided-difference equation of the hypergeometric type on non-uniform lattices, generalizing therefore previous work proving existence ...

Application of identical transformations in Cauchy problem solving

Тонкие химические технологии, 2009
A polynomial method of Cauchy problem solving is presented. The method allows constructing a fundamental solution in locally analytical form for any type of function of the right part of the equation for normal form of differential equation.

Partial Differential Equations and Bivariate Orthogonal Polynomials

Journal of Symbolic Computation, 1999
The author solves the Non-Hermitian Bochner Problem (NHBP): find all triples \((L_1, L_2, P)\) where \(P\) is a family of bivariate orthogonal polynomials and \(L_1\) and \(L_2\) are the second-order linear partial differential operators which satisfy such conditions \(\phi (1)=1,\) \(\phi (\overline{z})=\overline{\phi (z)},\) \(\overline{\phi}\in P,\)

"Exact WKB integration'' of polynomial 1D Schr\"odinger (or Sturm-Liouville) problem

, 2001
We review an "exact semiclassical" resolution method for the general stationary 1D Schr\"odinger equation with a polynomial potential. This method avoids having to compute any Stokes phenomena directly; instead, it basically relies on an elementary ...
