Differential Games of Multiple Agents and Geometric Structures [chapter]

Panos M. Pardalos, Vitaliy A. Yatsenko, Altannar Chinchuluun, Artyom G. Nahapetyan
2008 Pareto Optimality, Game Theory And Equilibria  
This chapter deals with problems of differential games of multiple agents moving in a region. We describe such a game by a hierarchical structure, which can be simplified using a fiber bundle.  ...  In addition we also consider a cooperative problem when the agent's motions must satisfy a separation constraint throughout the encounter to be conflict-free.  ...  In fact, when the system is analytic, strong accessibility and the rank condition A x = T x X for every x ∈ X, are equivalent.  ...

Statistical steady state in turbulent droplet condensation

Christoph Siewert, Jérémie Bec, Giorgio Krstulovic
2016 Journal of Fluid Mechanics  
Motivated by systems in which droplets grow and shrink in a turbulence-driven supersaturation field, we investigate the problem of turbulent condensation in a general manner.  ...  The main mechanism involved in this convergence is a loss of memory induced by a significant number of droplets undergoing a complete evaporation before growing again.  ...  However, it is possible to understand qualitatively the system dynamics. A typical trajectory in the phase space is shown in Fig. 4 .  ...
