The filling radius function R of Gromov measures the minimal radii of van Kampen diagrams filling edge-circuits w in the Cayley 2-complex of a finite presentation P. It is known that the Dehn function...
On a Devil's staircase associated to the joint spectral radii of a family of pairs of matrices
Joint spectral radius Devil’s staircase finiteness conjecture Sturmian sequence balanced word
2011/9/14
Abstract: The joint spectral radius of a finite set of real d x d matrices is defined to be the maximum possible exponential rate of growth of products of matrices drawn from that set. In previous wor...
Surface convection and red giants radii measurements
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
The phenomenological models of convection use characteristic length scales they do not determine but that are chosen to fit solar or stellar observations. We investigate if changes of these length sca...
Resonant radii of kHz quasi-periodic oscillations in Keplerian discs orbiting neutron stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
Exchange of dominance between twin kHz quasi-periodic oscillations (QPOs) observed in some low-mass-X-ray-binaries (LMXB) suggests the possibility of a resonance between two oscillatory modes.
Radii of starlikeness for certain subclasses of logharmonic mappings
logharmonic univalent starlikeness
2010/9/17
In this paper, we determine the radius of univalence and starlikeness for subclasses of logharmonic mappings which satisfy certain conditions. Moreover, we obtain the radius of univalence and starlike...
Comment on "Comparisons with analytical solutions from Khvorostyanov and Curry (2007) on the critical droplet radii and supersaturations of CCN with insoluble fractions" by Kokkola et al. (2008)

2009/8/25
Analytical solutions for the critical radii and supersaturations of the cloud condensation nuclei (CCN) with insoluble fractions were derived by Khvorostyanov and Curry (2007, hereafter KC07). These s...

Effects of Opacity on Stellar Radii and Their Relevance to Observational Data
general-structure modelling opacity tables observational tests eclipsing binary data
2010/4/9
We have examined the effect of varying opacities on envelope structure with the aid of Paczynski's public domain stellar modelling programs. For this, we prepared new opacity tables from the data of K...
