On the approximation of one Markov chain by another
Mark Jerrum
Motivated by applications in Markov chain Monte Carlo, we discuss what it means for one Markov chain to be an approximation to another. Specifically included in that discussion are…
The Shape of the Big Blue Bump as Revealed by Spectropolarimetry
R. Antonucci, M. Kishimoto, C. Boisson +1
Thermal models for the quasar Big Blue Bump generally lead to bound-free continuum features, which may be in absorption or emission. Searches for Lyman edges attributable to quasar…
Searching For Planetary Transits In The Open Cluster NGC 7789
D. M. Bramich, K. D. Horne, I. A. Bond
Open clusters are ideal targets for searching for transiting Hot Jupiters. They provide a relatively large concentration of stars on the sky and cluster members have similar metall…
Schematic mode coupling theories for shear thinning, shear thickening, and jamming
M. E. Cates, C. B. Holmes, M. Fuchs +1
Mode coupling theory (MCT) appears to explain several, though not all, aspects of the glass transition in colloids (particularly when short-range attractions are present). Developm…
Ricci-corrected derivatives and invariant differential operators
David M. J. Calderbank, Tammo Diemer, Vladimir Soucek
We introduce the notion of Ricci-corrected differentiation in parabolic geometry, which is a modification of covariant differentiation with better transformation properties. This e…
The formation of cluster elliptical galaxies as revealed by extensive star formation
J. A. Stevens, R. J. Ivison, J. S. Dunlop +6
The most massive galaxies in the present-day Universe are found to lie in the centres of rich clusters. They have old, coeval stellar populations suggesting that the bulk of their…
