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".
