The Linear Escape Limit Set
If G is any Kleinian group, we show that the dimension of the limit set Λ is always equal to either the dimension of the bounded geodesics or the dimension of the geodesics that escape to infinity at linear speed. Suppose G is a discrete group of isometries on hyperbolic space B, n ≥ 2. The limit set Λ ⊂ Sn−1 is defined to be the accumulation set of the G-orbit of 0 ∈ B. A point x ∈ Λ can be as...
متن کاملOscillatory Behavior of the Rate of Escape through an Unstable Limit Cycle.
Suppose a two-dimensional dynamical system has a stable attractor that is surrounded by an unstable limit cycle. If the system is additively perturbed by white noise, the rate of escape through the limit cycle will fall off exponentially as the noise strength tends to zero. By analyzing the associated Fokker–Planck equation we show that in general the weak-noise escape rate is non-Arrhenius: it...
متن کاملMission : Impossible ( Escape from the Lyman Limit ) ⋆
We investigate the intrinsic opacity of high-redshift galaxies to outgoing ionising photons using high-quality photometry of a sample of 27 spectroscopically-identified galaxies of redshift 1.9 < z < 3.5 in the Hubble Deep Field. Our measurement is based on maximum-likelihood fitting of model galaxy spectral energy distributions— including the effects of intrinsic Lyman-limit absorption and ran...
متن کاملDiscontinuity of a Degenerating Escape Rate
We look at degenerating meromorphic families of rational maps on P – holomorphically parameterized by a punctured disk – and we provide examples where the bifurcation current fails to have a bounded potential in a neighborhood of the puncture. This is in contrast to the recent result of Favre-Gauthier that we always have continuity across the puncture for families of polynomials; and it provide...
متن کاملRe: Call to establish a national lower limit of viability.
Ann Saudi Med 28(1) January-February 2008 www.saudiannals.net 1 The birth of premature infant of extremely low birthweight (ELBW), around the margins of viability, poses difficult management decisions for health professionals and parents because mortality, morbidity, and human and economic costs are high, and the likelihood of long-term survival without disabilities is low.1,2 Admittedly, the d...
