The thermodynamic formalism of Ruelle, Sinai, and Bowen, in which chaotic properties of dynamical systems are expressed in terms of a free energy-type function ψ(β), is applied to a Lorentz Lattice Gas, as typical for diffusive systems with static disorder. In the limit of large system sizes, the mechanism and effects of localization on large clusters of scatterers in the calculation of ψ(β) ar...

<p style='text-indent:20px;'>It is known that hyperbolic maps admitting singularities have at most countably many ergodic Sinai-Ruelle-Bowen (SRB) measures. These include the Belykh attractor, geometric Lorenz and more general Lorenz-type systems. In this paper, we establish easily verifiable sufficient conditions guaranteeing number of SRB measures finite, provide examples nonexamples sh...

We consider the number of Bowen sets which are necessary to cover a large measure subset of the phase space. This introduce some complexity indicator characterizing different kind of (weakly) chaotic dynamics. Since in many systems its value is given by a sort of local entropy, this indicator is quite simple to be calculated. We give some example of calculation in nontrivial systems (interval e...

As Jennifer Bowen's career progressed from music cataloging to administration, her personal involvement in and responses a great number of the major issues challenges is covered. These inclu...
