The Numerical Method for Solving Differential Equations of Lane-Emden Type by Padé Approximation

open access: yesDiscrete Dynamics in Nature and Society, 2011
Numerical solution differential equation of Lane-Emden type is considered by Padé approximation. We apply these method to two examples. First differential equation of Lane-Emden type has been converted to power series by one-dimensional differential ...

Physical applications of second-order linear differential equations that admit polynomial solutions

open access: yes, 2010
Conditions are given for the second-order linear differential equation P3 y" + P2 y'- P1 y = 0 to have polynomial solutions, where Pn is a polynomial of degree n. Several application of these results to Schroedinger's equation are discussed.

Stochastic Differential Equations

open access: yesJournal of Multivariate Analysis, 1974
AbstractWhen a system is acted upon by exterior disturbances, its time-development can often be described by a system of ordinary differential equations, provided that the disturbances are smooth functions. But for sound reasons physicists and engineers usually want the theory to apply when the noises belong to a larger class, including for example ...

On stochastic differential equations and a generalised Burgers equation [PDF]

open access: yes, 2012
In this paper, we discuss a link of Itˆo’s stochastic differential equa- tions to nonlinear partial differential equations of Burgers type. Un- der certain conditions, we derive a generalised Burgers equation from a stochastic differential equation.

Picard-Fuchs equations for Feynman integrals

open access: yes, 2013
We present a systematic method to derive an ordinary differential equation for any Feynman integral, where the differentiation is with respect to an external variable. The resulting differential equation is of Fuchsian type. The method can be used within

Initial value problems of fractional order Hadamard-type functional differential equations

open access: yesElectronic Journal of Differential Equations, 2015
The Banach fixed point theorem and a nonlinear alternative of Leray-Schauder type are used to investigate the existence and uniqueness of solutions for fractional order Hadamard-type functional and neutral functional differential equations.

Mean-field approximation of counting processes from a differential equation perspective

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
Deterministic limit of a class of continuous time Markov chains is considered based purely on differential equation techniques. Starting from the linear system of master equations, ordinary differential equations for the moments and a partial ...

DIFFERENTIAL EQUATIONS ON GRAPHS [PDF]

open access: yesMathematics of the USSR-Sbornik, 1972
Summary: The differential equations encountered in various applications may be treated as equations on graphs. In the paper it is shown that the structure of the graph allows us to investigate the properties of the solutions of such equations.
