We study properties of functions with bounded variation in Carnot-Carathéodory spaces. We prove their almost everywhere approximate differentiability and we examine their approximate discontinuity set and the decomposition of their distributional derivatives. Under an additional assumption on the space, called property R, we show that almost all approximate discontinuities are of jump type and we study a representation formula for the jump part of the derivative.

Lipschitz Carnot-Carathéodory Structures and their Limits
Antonelli, Gioacchino; Le Donne, Enrico; Nicolussi Golo, Sebastiano (Springer Science and Business Media LLC, 2023)In this paper we discuss the convergence of distances associated to converging structures of Lipschitz vector fields and continuously varying norms on a smooth manifold. We prove that, under a mild controllability assumption ... -
A Primer on Carnot Groups: Homogenous Groups, Carnot-Carathéodory Spaces, and Regularity of Their Isometries
Le Donne, Enrico (De Gruyter Open, 2017)Carnot groups are distinguished spaces that are rich of structure: they are those Lie groups equipped with a path distance that is invariant by left-translations of the group and admit automorphisms that are dilations with ... -
Subgraphs of BV functions on RCD spaces
Antonelli, Gioacchino; Brena, Camillo; Pasqualetto, Enrico (Springer Science and Business Media LLC, 2024)In this work we extend classical results for subgraphs of functions of bounded variation in Rn×R to the setting of X×R, where X is an RCD(K,N) metric measure space. In particular, we give the precise expression of the ... -
Local minimizers and gamma-convergence for nonlocal perimeters in Carnot groups
Carbotti, Alessandro; Don, Sebastiano; Pallara, Diego; Pinamonti, Andrea (EDP Sciences, 2021)We prove the local minimality of halfspaces in Carnot groups for a class of nonlocal functionals usually addressed as nonlocal perimeters. Moreover, in a class of Carnot groups in which the De Giorgi’s rectifiability theorem ... -
Semigenerated Carnot algebras and applications to sub-Riemannian perimeter
Le Donne, Enrico; Moisala, Terhi (Springer, 2021)This paper contributes to the study of sets of finite intrinsic perimeter in Carnot groups. Our intent is to characterize in which groups the only sets with constant intrinsic normal are the vertical half-spaces. Our ...
