Asymptotic solutions of forced nonlinear second order differential equations and their extensions

open access: yes, 2007
Using a modified version of Schauder's fixed point theorem, measures of non-compactness and classical techniques, we provide new general results on the asymptotic behavior and the non-oscillation of second order scalar nonlinear differential equations on

Algebraic Properties of First Integrals for Scalar Linear Third-Order ODEs of Maximal Symmetry

open access: yesAbstract and Applied Analysis, 2013
By use of the Lie symmetry group methods we analyze the relationship between the first integrals of the simplest linear third-order ordinary differential equations (ODEs) and their point symmetries. It is well known that there are three classes of linear

ADDENDUM TO ‘A BOLTZMANN CORRECTION’

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2019
Some implications concerning an unobservable medium whose micro-motion (rotational motion in Faraday vortex tubes) produces magnetic phenomena after Maxwell, used in a previous article on the origin of Maxwell’s equation for the magnetic induction (JODEA,

Functional differential equations close to differential equations [PDF]

open access: yesBulletin of the American Mathematical Society, 1966
when the lag function r(t) is nearly constant for large /, and has also asked for conditions on the function r under which all solutions approach zero as t—» oo. The purpose of this announcement is to initiate a study of various stability and oscillation problems for equations with perturbed lag functions, and to suggest that a modification of the ...

Elliptic operators and their symbols

open access: yesDemonstratio Mathematica, 2019
We consider special elliptic operators in functional spaces on manifolds with a boundary which has some singular points. Such an operator can be represented by a sum of operators, and for a Fredholm property of an initial operator one needs a Fredholm ...
