Rectifiable sets in Heisenberg groups

ARGOMENTI: Convegni

SEMINARI DI EQUAZIONI DIFFERENZIALI E APPLICAZIONI
Giovedi' 23 ottobre alle ore 11 in aula 2BC/60 T.A.
Pertti Mattila (Universita' di Helsinky) terra' un seminario dal titolo "Rectifiable sets in Heisenberg groups".

-Abstract
Rectifiable sets in Euclidean spaces are some of the most basic objects of geometric measure theory with many applications. Recently there has been active interest in developing geometric measure theory in non-Euclidean spaces, in particular in Heisenberg groups. The talk is a brief survey of work done on rectifiability in Heisenberg groups with particular emphasis on my recent work with Francesco Serra Cassano and Raul Serapioni on characterizations of rectifiability in terms of tangent subgroups and tangent measures.

Rif. int. M. Bardi, D. Vittone, A. Cesaroni
