Lie symmetry analysis, conservation laws and diverse solutions of a new extended (2+1)-dimensional Ito equation

open access: yesAIMS Mathematics, 2023
In this paper, a new class of extended (2+1)-dimensional Ito equations is investigated for its group invariant solutions. The Lie symmetry method is employed to transform the nonlinear Ito equation into an ordinary differential equation.

Computing the Galois group of some parameterized linear differential equation of order two [PDF]

open access: yes, 2011
We extend Kovacic's algorithm to compute the differential Galois group of some second order parameterized linear differential equation. In the case where no Liouvillian solutions could be found, we give a necessary and sufficient condition for the ...

Moment Boundedness of Linear Stochastic Delay Differential Equation with Distributed Delay [PDF]

open access: yes, 2012
This paper studies the moment boundedness of solutions of linear stochastic delay differential equations with distributed delay. For a linear stochastic delay differential equation, the first moment stability is known to be identical to that of the ...

Differential Equivalence for Linear Differential Algebraic Equations [PDF]

open access: yesIEEE Transactions on Automatic Control, 2022
Differential-algebraic equations (DAEs) are a widespread dynamical model that describes continuously evolving quantities defined with differential equations, subject to constraints expressed through algebraic relationships. As such, DAEs arise in many fields ranging from physics, chemistry, and engineering.

Half-linear Euler differential equation and its perturbations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We investigate oscillatory properties of perturbed half-linear Euler differential equation. We give an alternative proof (simpler and more straightforward) of the main result of [O. Došlý, H. Funková, Abstr. Appl. Anal. 2012, Art. ID 738472] and we prove
