Absorbing sets and Baker domains for holomorphic maps [PDF]

Journal of the London Mathematical Society, 2021
We consider holomorphic maps $f: U \to U$ for a hyperbolic domain $U$ in the complex plane, such that the iterates of $f$ converge to a boundary point $ $ of $U$. By a previous result of the authors, for such maps there exist nice absorbing domains $W \subset U$. In this paper we show that $W$ can be chosen to be simply connected, if $f$ has parabolic

Absorbing sets of homogeneous subtractive algorithms [PDF]

Monatshefte für Mathematik, 2012
We consider homogeneous multidimensional continued fraction algorithms, in particular a family of maps which was introduced by F. Schweiger. We prove his conjecture regarding the existence of an absorbing set for those maps. We also establish that their renormalisations are nonergodic which disproves another conjecture due to Schweiger.

Absorbing Sets of Generalized LDPC Codes [PDF]

, 2018
In this paper we propose a definition of Absorbing Sets for binary Generalized LDPC (GLDPC) codes. We show that under practical Max-Log iterative decoding, our AS definition enables a local description of the message evolution with the iterations, with a simplified model very similar to the one used for the analysis of Min-Sum LDPC decoding ...

Thresholds of Absorbing Sets in Low-Density Parity-Check Codes [PDF]

IEEE Transactions on Communications, 2017
In this paper, we investigate absorbing sets, responsible of error floors in Low Density Parity Check codes. We look for a concise, quantitative way to rate the absorbing sets' dangerousness. Based on a simplified model for iterative decoding evolution, we show that absorbing sets exhibit a threshold behavior. An absorbing set with at least one channel

Absorbing Cantor sets in dynamical systems: Fibonacci maps

Annals of Mathematics, 1994
In this paper we shall show that there exists a polynomial unimodal map f: [0,1] -> [0,1] which is 1) non-renormalizable(therefore for each x from a residual set, $ (x)$ is equal to an interval), 2) for which $ (c)$ is a Cantor set, and 3) for which $ (x)= (c)$ for Lebesgue almost all x.

Sizing optimization of microstructure of sound-absorbing poroelastic material by homogenization method

Nihon Kikai Gakkai ronbunshu, 2020
Acoustic properties of sound-absorbing poroelastic media such as sound absorption coefficient are affected by microscopic structures. However, the design method for microscopic structures of sound-absorbing poroelastic media has not been established and ...

Calibration of absorbing boundary layers for geoacoustic wave modeling in pseudo-spectral time-domain methods [PDF]

Geoscientific Model Development, 2023
This paper develops a calibration methodology of the artificial absorbing techniques typically used by Fourier pseudo-spectral time-domain (PSTD) methods for geoacoustic wave simulations.

Characterization and intercomparison of aerosol absorption photometers: result of two intercomparison workshops [PDF]

Atmospheric Measurement Techniques, 2011
Absorption photometers for real time application have been available since the 1980s, but the use of filter-based instruments to derive information on aerosol properties (absorption coefficient and black carbon, BC) is still a matter of debate.
