报告摘要:One of interesting problems in classical geometry is to find the envelope for a family of lines or hypersurfaces in the Euclidean spaces and several applications to Economics and Mathematical Optimization have been developed. After a review of our previous works for finding the pseudohermitian invariants in CR geometry, we will show the necessary and sufficient conditions for the existence of horizontal envelops in the 3D-Heisenberg group by using the standard techniques in Integral Geometry. We obtain a method to construct horizontal envelopes from the given ones and characterize the solutions satisfying the construction. The similar results can be generalized to the higher dimensional Heisenberg groups.
