*Sebastiano Don*

(Università di Jyväskylä, Finlandia)




Terrà un seminario dal titolo:



*“Fine properties of BV functions in Carnot-Carathéodory spaces”*





*Abstract:*

Carnot-Carathéodory spaces are metric spaces arising from a system of
vector fields in $\mathbb R^n$ satisfying a suitable non-involutivity
assumption and they appear naturally in the study of non-holonomic control
systems. We study structural properties of the measure derivative of a
function of bounded variation in a CC space. We prove, in particular, that
a BV function is approximately differentiable almost everywhere and we
analyze the structure of its jump set. We finally show that, in a class of
CC spaces satisfying some suitable geometric assumptions, the formula for
the measure derivative of a BV function is analogous to the one available
in the Euclidean case.

This is a joint work with Davide Vittone.



Tutti gli interessati sono invitati a partecipare.
