stability analysis of fuzzy Polynomial fractional differential Systems using Sum-of-Squares [PDF]

open access: yesمجله مدل سازی در مهندسی, 2022
This paper discusses the stability analysis of fractional-order polynomial systems by using the sum of squares method. furthermore the feasibility of designing the problems demonstrates which can not be represented in LMIs.

On the polynomial differential systems having polynomial first integrals

open access: yesBulletin des Sciences Mathématiques, 2012
We consider the class of complex planar polynomial differential systems having a polynomial first integral. Inside this class the systems having minimal polynomial first integrals without critical remarkable values are the Hamiltonian ones. Here we mainly study the subclass of polynomial differential systems such that their minimal polynomial first ...

Analytic reducibility of nondegenerate centers: Cherkas systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016

Invariant Algebraic Curves of Generalized Liénard Polynomial Differential Systems

open access: yesMathematics, 2022
In this study, we focus on invariant algebraic curves of generalized Liénard polynomial differential systems x′=y, y′=−fm(x)y−gn(x), where the degrees of the polynomials f and g are m and n, respectively, and we correct some results previously stated.

Tropical differential equations [PDF]

open access: yes, 2015
Tropical differential equations are introduced and an algorithm is designed which tests solvability of a system of tropical linear differential equations within the complexity polynomial in the size of the system and in its coefficients.

Polynomial differential systems with hyperbolic algebraic limit cycles

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
For a given algebraic curve of degree $n$, we exhibit differential systems of degree greater than or equal $n$, by introducing functions which are solutions of certain partial differential equations.
