| Outline of Final Research Achievements |
(1) We proved the existence of integral lattices in the Lie groups attached to Clifford algebras and their admissible modules and classified them corresponding to minimal admissible modules. Also we studied the spectral zeta function of the sub-Laplacians on some of their Lie groups and their compact quotients by lattices which we proved the existence. (2) We constructed Green kernels for higher step Grushin operators coming from sub-Laplacians on higher step nilpotent Lie groups (Carnot groups) by two different methods. (3) A relation of the homogeneous first integrals of a sub-Laplacian and the related Grushin type operator through a submersion was proved in the framework of the pseudo-differential operator theory. (4) We constructed a codimension 3 sub-Riemannian structure on the Gromoll-Meyer exotic 7 sphere.
