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.

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 ... -
Area of intrinsic graphs and coarea formula in Carnot groups
Julia, Antoine; Nicolussi Golo, Sebastiano; Vittone, Davide (Springer Science and Business Media LLC, 2022)We consider submanifolds of sub-Riemannian Carnot groups with intrinsic C1 regularity (C1H). Our first main result is an area formula for C1H intrinsic graphs; as an application, we deduce density properties for Hausdorff ... -
Space of signatures as inverse limits of Carnot groups
Le Donne, Enrico; Züst, Roger (EDP Sciences, 2021)We formalize the notion of limit of an inverse system of metric spaces with 1-Lipschitz projections having unbounded fibers. The construction is applied to the sequence of free Carnot groups of fixed rank n and increasing ...
