Critical parameters of an oval billiard with an elliptical component
Anne Kétri P. da Fonseca, Joelson D. V. Hermes, Edson D. Leonel
We explore the critical parameters responsible for the transition from integrability to chaos in a family of billiards combining elliptical and oval deformations. Unlike standard o…
Cyclicity of Rigid Centers on Center Manifolds of Three-dimensional systems
Claudio Pessoa, Lucas Queiroz, Jarne D. Ribeiro
We work with polynomial three-dimensional rigid differential systems. Using the Lyapunov constants, we obtain lower bounds for the cyclicity of the known rigid centers on their cen…
Solar System constraints on Renormalization Group extended General Relativity: The PPN and Laplace-Runge-Lenz analyses with the external potential effect
Davi C. Rodrigues, Sebastião Mauro, Álefe O. F. de Almeida
General Relativity extensions based on Renormalization Group effects are motivated by a known physical principle and constitute a class of extended gravity theories that have some…
