Dynamical systems analysis of fluid transport in time-periodic vortex ring flows [PDF]
, 2006 It is known that the stable and unstable manifolds of dynamical systems theory provide a powerful tool for understanding Lagrangian aspects of time-periodic flows. In this work we consider two time-periodic vortex ring flows.

Gauge fixing in (2+1)-gravity with vanishing cosmological constant [PDF]
, 2012 We apply Dirac's gauge fixing procedure to (2+1)-gravity with vanishing cosmological constant. For general gauge fixing conditions based on two point particles, this yields explicit expressions for the Dirac bracket.

Realization of tangent perturbations in discrete and continuous time conservative systems [PDF]
, 2013 We prove that any perturbation of the symplectic part of the derivative of a Poisson diffeomorphism can be realized as the derivative of a $C^1$-close Poisson diffeomorphism.

Spatial Directions, Anisotropy and Special Relativity [PDF]
, 2011 The concept of an objective spatial direction in special relativity is investigated and theories assuming light-speed isotropy while accepting the existence of a privileged spatial direction are classified.

Periodic bouncing solutions for sublinear impact oscillator
AIMS Mathematics, 2021 The existence of periodic bouncing solutions for sublinear impact oscillator is proved by using Poincaré-Birkhoff twist theorem. The approach of this paper is based on a well defined successor map and the phase-plane analysis of the spiral properties.

Horseshoe Chaos in a Simple Memristive Circuit
Journal of Applied Mathematics, 2014 A simple memristive circuit model is revisited and the stability analysis is to be given. Furthermore, we resort to Poincaré section and Poincaré map technique and present rigorous computer-assisted verification of horseshoe chaos by virtue of ...

The state-dependent impulsive control for a general predator–prey model
Journal of Biological Dynamics, 2021 In this paper, a general predator–prey model with state-dependent impulse is considered. Based on the geometric analysis and Poincaré map or successor function, we construct three typical types of Bendixson domains to obtain some sufficient conditions ...
