Braided rings: a scattering billiard model
نویسنده
چکیده
We introduce a billiard scattering model consisting of two non-overlapping rotating discs in the context of the formation and structural properties of planetary rings. We show that due to the arrangement of the symmetric periodic orbits, stable orbits are found which in the configuration space lead to the appearance of patterns qualitatively similar to planetary rings. Rings associated with different stability regions are naturally braided; different braids may overlap displaying features similar to clumps. Erosion mechanisms within the model are discussed.

Narrow rings: a scattering billiard model
We propose a generic mechanism for the formation of narrow rings in rotating systems. For this purpose we use a system of discs rotating about a common center lying well outside the discs. A discussion of this system shows that narrow rings occur, if we assume noninteracting particles. A saddle-center bifurcation is responsible for the relevant appearance of elliptic regions in phase space, tha...
متن کاملSolutions of the Yang-baxter Equations from Braided-lie Algebras and Braided Groups
We obtain an R-matrix or matrix representation of the Artin braid group acting in a canonical way on the vector space of every (super)-Lie algebra or braided-Lie algebra. The same result applies for every (super)-Hopf algebra or braided-Hopf algebra. We recover some known representations such as those associated to racks. We also obtain new representations such as a non-trivial one on the ring ...
متن کاملLax Operad Actions and Coherence for Monoidal N -categories, A∞ Rings and Modules
We establish a general coherence theorem for lax operad actions on an n-category which implies that an n-category with such an action is lax equivalent to one with a strict action. This includes familiar coherence results (e.g. for symmetric monoidal categories) and many new ones. In particular, any braided monoidal n-category is lax equivalent to a strict braided monoidal n-category. We also o...
متن کاملThe Two-Processor Reliability of Hierarchical Large-Scale Ring-Based Networks
In this paper we present the reliability analysis of ring-based hierarchical directed networks in the context of large-scale multiprocessors. A wide range of hierarchical structures based on the basic, dual counter-rotating, and braided (skip-a-node) rings are analyzed and compared in thispaper. We have adopted the two-processor (two-temzinal) reliability criteria for our analysis. The results ...
متن کاملIrregular Scattering of Particles Confined to Ring-Bounded Cavities
The classical motion of a Ii"ee particle that scatters elastically from ring-bounded cavities is analyzed nunaerically. When the ring is a smooth circle the scattering follows a regular and periodic pattern. However, for rings composed of N scatrefers the Ilow is irregular, of Lyapunov type. The Lyapunov exponent is found to depend logarithmically with N, which is consistent with the theoretica...
