Ja n 20 08 Classification of Harish - Chandra modules over the W - algebra W ( 2 , 2 ) ∗
In this paper, we classify all irreducible weight modules with finite dimensional weight spaces over the W -algebra W (2, 2). Meanwhile, all indecomposable modules with one dimensional weight spaces over the W -algebra W (2, 2) are also determined.
متن کامل2 3 Fe b 20 09 WHITTAKER MODULES FOR THE W - ALGEBRA W ( 2 , 2 )
In this paper, Whittaker modules for the W -algebra W (2, 2) are studied. We obtain analogues to several results from the classical setting and the case of the Virasoro algebra, including a classification of simple Whittaker modules by central characters and composition series for general Whittaker modules.

متن کاملModeling skewed distributions using multifractals and the W-20 law’
The focus of this paper is on the characterization of the skewness of an attributevalue distribution and on the extrapolations for interesting parameters. More specifically, given a vector with the highest h multiplicities ci = (rnl,rn2, . . . . mh), and some frequency moments Fp = Crnj, (e.g., q = 0,2), we provide effective schemes for obtaining estimates about either its statistics or subsets...
متن کاملThe Connection between W 31 , SGR 1806 - 20 , & LBV 1806 - 20 : Distance , Extinction , and Structure
We present new millimeter and infrared spectroscopic observations towards the radio nebula G10.0−0.3, which is powered by the wind of the Luminous Blue Variable star LBV 1806−20 also closely associated with the soft gamma-ray repeater SGR 1806−20, and believed to be located in the giant Galactic H ii complex W31. Based on observations of CO emission lines and NH3 absorption features from molecu...
