Abstract:
The talk will introduce and demonstrate through examples a Tanaka-theoretic general method (developed in joint work with Igor Zelenko) for solving local equivalence problems applicable to a broad class of 2-nondegenerate hypersurface-type CR manifolds, namely to all such structures that are uniquely determined by the geometry naturally induced on their associated Levi leaf space. We will apply the general method to an instructive family of CR hypersurfaces in complex 6-space, reducing their local equivalence problem to one of absolute parallelisms that we explicitly construct in local coordinates. The talk will also review further applications of the general method, applications to estimating symmetry group dimensions and to classifications of homogeneous structures.
