Some Remarks on the Location of Non-Asymptotic Zeros of Whittaker and Kummer Hypergeometric Functions
Islam Boussaada, Guilherme Mazanti, Silviu-Iulian Niculescu
This paper focuses on the location of the non-asymptotic zeros of Whittaker and Kummer confluent hypergeometric functions. Based on a technique by E. Hille for the analysis of solu…
Complexity reduction of C-algorithm
Magali Bardet, Islam Boussaada
The C-Algorithm introduced in [Chouikha2007] is designed to determine isochronous centers for Lienard-type differential systems, in the general real analytic case. However, it has…
Isochronicity conditions for some real polynomial systems
Islam Boussaada
This paper focuses on isochronicity of linear center perturbed by a polynomial. Isochronicity of a linear center perturbed by a degree four and degree five polynomials is studied,…
On the existence of periodic solution of perturbed generalized Liénard equations
Islam Boussaada, A. Raouf Chouikha
Under conditions of Levinson-Smith type, we prove the existence of a -periodic solution for the perturbed generalized Liénard equation u''+ϕ(u,u')u'+ψ(u)=εω(\frac{t}τ,u,u') with…
