The Lie Algebra Cohomology of JetsYunhyong KimYunhyong KimMax-Planck Institut für Mathematik Vivatsgasse 7 D-53111 Bonn Germany kimy@mpim-bonn.mpg.de Abstract: Let $\g$ be a finite-dimensional complex semi-simple Lie algebra. We present a new calculation of the continuous cohomology of the Lie algebra $z \g[[z]]$. In particular, we shall give an explicit formula for the Laplacian on the Lie algebra cochains, from which we can deduce that the cohomology in each dimension is a finite-dimensional representation of $\g$ which contains any irreducible representation of $\g$ at most once. Classification (MSC2000): 17B56; 17B65 Full text of the article:
