Intrinsic submanifold of the Heisenberg group
Abstract.
In this talk we provide a sketch of some recent joint results with R. Serapioni and F. Serra Cassano, concerning an intrinsic definition of submanifold of arbitrary dimension in the Heisenberg group, as well as characterization of the intrinsic Hausdorff measure concentrated on these submanifolds. It turns out that the notion of submanifold deeply changes passing from "low dimension" to "low codimension".
