    "abstract": "We describe a class of non-central extensions of the diffeomorphism algebra\nin N-dimensional spacetime, and construct lowest-energy modules thereof, thus\ngeneralizing work of Eswara-Rao and Moody. There is one representation for each\nrepresentation of $Vir\\ltimes_{k_0}\\km{gl(N)}$ (an extension of the semi-direct\nproduct). Similar modules are constructed for gauge algebras.",
