Second cohomology and nilpotency class 2Sinisa Crvenkovic, Vladimir TasicPrirodno-matematicki fakultet, 21000 Novi Sad, Serbia and Department of Mathematics and Statistics, University of New Brunswick, Fredericton, NB, Canada E3B 5A3Abstract: Conditions are given for a class 2 nilpotent group to have no central extensions of class 3. This is related to Betti numbers and to the problem of representing a class 2 nilpotent group as the fundamental group of a smooth projective variety. Keywords: nilpotent groups; Lie algebras; cohomology; projective varieties Classification (MSC2000): 20J06; 57T10; 20F18; 57M05 Full text of the article: (for faster download, first choose a mirror)
