On bounded solutions of differential systems

Вестник КазНУ. Серия математика, механика, информатика, 2022
The question of the existence of bounded solutions on an infinite interval of a linear inhomogeneous system of ordinary differential equations in a finite-dimensional space is considered. The study of bounded solutions of systems of ordinary differential

CLASSIFICATION OF FUNCTIONS IN ASSOCIATION WITH DIFFERENTIAL EQUATIONS [PDF]

Matrix Science Mathematic
A new classification of functions is presented in this work in relation to ordinary differential equations. A function for which the n’th derivative of it can be expressed in terms of linear combinations of lower derivatives and the function itself is ...

A refined invariant subspace method and applications to evolution equations

, 2012
The invariant subspace method is refined to present more unity and more diversity of exact solutions to evolution equations. The key idea is to take subspaces of solutions to linear ordinary differential equations as invariant subspaces that evolution ...

Oscillation and non-oscillation of half-linear differential equations with coeffcients determined by functions having mean values

Open Mathematics, 2018
The paper belongs to the qualitative theory of half-linear equations which are located between linear and non-linear equations and, at the same time, between ordinary and partial differential equations.

Polynomial quasisolutions of linear differential-difference equations [PDF]

Opuscula Mathematica, 2006
The paper discusses a linear differential-difference equation of neutral type with linear coefficients, when at the initial time moment \(t=0\) the value of the desired function \(x(t)\) is known. The authors are not familiar with any results which would

Quantum algorithm for time-dependent differential equations using Dyson series [PDF]

Quantum
Time-dependent linear differential equations are a common type of problem that needs to be solved in classical physics. Here we provide a quantum algorithm for solving time-dependent linear differential equations with logarithmic dependence of the ...
