Two characterization of BV functions on Carnot groups via the heat semigroup
, 2011 In this paper we provide two different characterizations of sets with finite perimeter and functions of bounded variation in Carnot groups, analogous to those which hold in Euclidean spaces, in terms of the short-time behaviour of the heat semigroup. The

Starshapedeness for fully-nonlinear equations in Carnot groups [PDF]
, 2018 In this paper we establish the starshapedness of the level sets of the capacitary potential of a large class of fully-nonlinear equations for condensers in Carnot groups, once a natural notion of starshapedness has been introduced.

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?
International Journal of Climatology, EarlyView.Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.

Validation of the Milan Score Using Prolonged Wireless PH Monitoring
Alimentary Pharmacology &Therapeutics, EarlyView.The Milan Score, a high‐resolution manometry‐derived tool, predicts pathological GERD on 96‐h wireless pH monitoring with high specificity and positive predictive value, maintaining robust discriminative performance across both typical and atypical symptom profiles and outperforming single HRM parameters as a standalone manometric parameter.

Rectifiability in Carnot Groups
, 2022 This thesis is devoted to the study of the theory of rectifiability of sets and measures in the non smooth context of Carnot groups. The focus is on the study of the notion of P-rectifiability and its relation with other notions of rectifiability in Carnot groups.

Anomeric Amides: Valuable Reagents in Synthetic Organic Chemistry
Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.Enabling late‐stage transformations and skeletal editing, anomeric amides have recently emerged as powerful synthetic tools. Due to their unique properties, anomeric amides have been employed in reactions ranging from amination to halogenation. This minireview provides an overview of recent progress in using anomeric amides across a variety of ...

Curvature exponent and geodesic dimension on Sard-regular Carnot groups
Analysis and Geometry in Metric SpacesIn this study, we characterize the geodesic dimension NGEO{N}_{{\rm{GEO}}} and give a new lower bound to the curvature exponent NCE{N}_{{\rm{CE}}} on Sard-regular Carnot groups.

Functional properties of limits of Sobolev homeomorphisms with integrable distortion
Современная математика: Фундаментальные направленияThe functional and geometric properties of limits of homeomorphisms with integrable distortion of domains in Carnot groups are studied. The homeomorphisms belong to Sobolev classes.

Integral Representation of Local Left–Invariant Functionals in Carnot Groups
Analysis and Geometry in Metric Spaces, 2019 The aim of this note is to prove a representation theorem for left–invariant functionals in Carnot groups. As a direct consequence, we can also provide a Г-convergence result for a smaller class of functionals.

Almost uniform domains and Poincaré inequalities
Transactions of the London Mathematical Society, 2021 Here we show existence of many subsets of Euclidean spaces that, despite having empty interior, still support Poincaré inequalities with respect to the restricted Lebesgue measure.
