Toric Kempf–Ness sets
In the theory of algebraic group actions on affine varieties, the concept of a Kempf– Ness set is used to replace the categorical quotient by the quotient with respect to a maximal compact subgroup. Using recent achievements of “toric topology,” we show that an appropriate notion of a Kempf–Ness set exists for a class of algebraic torus actions on quasiaffine varieties (coordinate subspace arra...
متن کاملStructural Mad-ness
ammalian sex-determining factors with homology to DNA binding proteins are required for splicing, according to a study by Paolo SassoneCorsi and coworkers at the Université Louis Pasteur (Strasbourg, France). Examination of high mobility group (HMG) domain containing SRY and Sox proteins demonstrated a surprising but clear association with splicing complexes. SRY, the testis-determining factor ...
متن کاملBrownian Couplings, Convexity, and Shy-ness
Benjamini, Burdzy, and Chen (2007) introduced the notion of a shy coupling: a coupling of a Markov process such that, for suitable starting points, there is a positive chance of the two component processes of the coupling staying at least a given positive distance away from each other for all time. Among other results, they showed that no shy couplings could exist for reflected Brownian motions...
