Their classification is well known; our focus in this paper is on the deformations, which yield a picture of how the moduli space is assembled. Surprisingly, we get a nice geometric description of this moduli space essentially as an orbifold, with just a few exceptional points.41 pages, 1 figureRepresentation TheoryQuantum Algebra17B56 (Primary); 14D15,13D10,14B12,16S80,16E40 (Secondary)Deformations of Four Dimensional Lie Algebrastext
