DESCRIPTION:Der-Chen Chang (Georgetown)\nAbstract: The unit sphere S3 can b
 e identified\nwith the unitary group SU(2). Under this identification the 
 unit\nsphere can be considered as a non-commutative Lie group. The\ncommut
 ation relations for the vector fields of the corresponding\nLie algebra de
 fine a 2-step sub-Riemannian manifold. We study\nsub-Riemannian geodesics 
 on this sub-Riemannian manifold making use\nof the Hamiltonian formalism. 
 We also discuss some properties of\nthe heat kernel for the sub-Laplacian.
