Let (V, 0) be an isolated hypersurface singularity. We introduce some  new finite dimensional Lie algebras L^k(V) and L_k(V) associated to (V, 0) and propose some conjectures. We prove that some of these Lie algebras characterize the ADE singularities completely and even more general singularities. Moreover, we will also present our recent progress on some conjectures about those Lie algebras. This is based on the joint work with N. Hussain and S. S.-T. Yau.
