Extensions and corona decompositions of low-dimensional intrinsic Lipschitz graphs in Heisenberg groups

Daniela Di Donato, Katrin Fässler

This note concerns low-dimensional intrinsic Lipschitz graphs, in the sense of Franchi, Serapioni, and Serra Cassano, in the Heisenberg group ${\mathbb{H}}^n$, $n\in \mathbb{N}$. For…
