The period function for second-order quadratic ODEs is monotone∗
Very little is known about the period function for large families of centers. In one of the pioneering works on this problem, Chicone [?] conjectured that all the centers encountered in the family of second-order differential equations ẍ = V (x, ẋ), being V a quadratic polynomial, should have a monotone period function. Chicone solved some of the cases but some others remain still unsolved. In ...
متن کامل2-Banach stability results for the radical cubic functional equation related to quadratic mapping
The aim of this paper is to introduce and solve the generalized radical cubic functional equation related to quadratic functional equation$$fleft(sqrt[3]{ax^{3}+by^{3}}right)+fleft(sqrt[3]{ax^{3}-by^{3}}right)=2a^{2}f(x)+2b^{2}f(y),;; x,yinmathbb{R},$$for a mapping $f$ from $mathbb{R}$ into a vector space. We also investigate some stability and hyperstability results for...
متن کاملPeriodic orbits contribution to the 2 - point correlation form factor for pseudo - integrable systems
The 2-point correlation form factor, K 2 (τ), for small values of τ is computed analytically for typical examples of pseudo-integrable systems. This is done by explicit calculation of periodic orbit contributions in the diagonal approximation. The following cases are considered: (i) plane billiards in the form of right triangles with one angle π/n and (ii) rectangular billiards with the Aharono...
متن کاملMultibump Orbits Continued from the Anti-integrable Limit for Lagrangian Systems
A continuous-time anti-integrable limit is considered in the context of time-dependent Lagrangian systems on the torus. The anti-integrable limit is the singular (or adiabatic) limit in the singularly (adiabatically, resp.) perturbed problems. This paper presents an implicit function theorem version of the results of Bolotin and MacKay (1997 Nonlinearity 1
متن کاملBinary Codes and Period-$2$ Orbits of Sequential Dynamical Systems
Let [Kn, f, π] be the (global) SDS map of a sequential dynamical system (SDS) defined over the complete graph Kn using the update order π ∈ Sn in which all vertex functions are equal to the same function f : F2 → F2 . Let ηn denote the maximum number of periodic orbits of period 2 that an SDS map of the form [Kn, f, π] can have. We show that ηn is equal to the maximum number of codewords in a b...
