We examine a class of Grushin type operators P k where k∈ N 0 defined in (1.1). The operators P k are non-elliptic and degenerate on a sub-manifold of R N+ ℓ. Geometrically they arise via a submersion from a sub-Laplace operator on a nilpotent Lie group of step k+ 1. We explain the geometric framework and prove some analytic properties such as essential self-adjointness. The main purpose of the paper is to give an explicit expression of the fundamental solution of P k. Our methods rely on an appropriate change of coordinates and involve the theory of Bessel and modified Bessel functions together with Weber's second exponential integral.
