From Brake to Syzygy
Richard Moeckel, Richard Montgomery, Andrea Venturelli
In the planar three-body problem, we study solutions with zero initial velocity (brake orbits). Following such a solution until the three masses become collinear (syzygy), we obtai…
Particles with spin in stationary flat spacetimes
Thierry Barbot, Catherine Meusburger
We construct stationary flat three-dimensional Lorentzian manifolds with singularities that are obtained from Euclidean surfaces with cone singularities and closed one-forms on the…
Analysis of Buffer Starvation with Application to Objective QoE Optimization of Streaming Services
Yuedong Xu, Eitan Altman, Rachid El-Azouzi +3
Our purpose in this paper is to characterize buffer starvations for streaming services. The buffer is modeled as an M/M/1 queue, plus the consideration of bursty arrivals. When the…
A Constrained Evolutionary Gaussian Multiple Access Channel Game
Quanyan Zhu, Hamidou Tembine, Tamer Basar
In this paper, we formulate an evolutionary multiple access channel game with continuous-variable actions and coupled rate constraints. We characterize Nash equilibria of the game…
Lower and upper bounds for the Lyapunov exponents of twisting dynamics: a relationship between the exponents and the angle of the Oseledet's splitting
Marie-Claude Arnaud
We consider locally minimizing measures for the conservative twist maps of the -dimensional annulus or for the Tonelli Hamiltonian flows defined on a cotangent bundle . Fo…
