MULTIFRACTAL ANALYSIS OF FUNCTIONS ON HEISENBERG AND CARNOT GROUPS [PDF]

Journal of the Institute of Mathematics of Jussieu, 2015
In this article, we investigate the pointwise behaviors of functions on the Heisenberg group. We find wavelet characterizations for the global and local Hölder exponents. Then we prove some a priori upper bounds for the multifractal spectrum of all functions in a given Hölder, Sobolev, or Besov space. These upper bounds turn out to be optimal, since in

A density result on a BV-type space on Carnot groups

Bruno Pini Mathematical Analysis Seminar
In the setting of Carnot groups (connected, simply connected and stratified Lie groups), we prove a density result for a BV-type space previously introduced in [3].

Uniform Gaussian Bounds for Subelliptic Heat Kernels and an Application to the Total Variation Flow of Graphs over Carnot Groups

Analysis and Geometry in Metric Spaces, 2013
In this paper we study heat kernels associated with a Carnot group G, endowed with a family of collapsing left-invariant Riemannian metrics σε which converge in the Gromov- Hausdorff sense to a sub-Riemannian structure on G as ε→ 0.

W2,p a priori estimates for nonvariational operators: the sharp maximal function technique

Bruno Pini Mathematical Analysis Seminar, 2018
We consider a nonvariational degenerate elliptic operator, structured on a system of left invariant, 1-homogeneous, Hörmander vector fields on a Carnot group, where the coefficient matrix is symmetric, uniformly positive on a bounded domain and the ...

Essential Information About Chronobiology and Chronotherapy for the Optimal Care of People With Bipolar Disorders: An Expert Consensus

Bipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Introduction Circadian dysfunction is involved in the pathophysiology of bipolar disorders (BD), and circadian‐based interventions are gaining recognition in their management. Moreover, basic and epidemiologic research has generated findings inspiring circadian‐informed self‐ and clinician‐management strategies.

Uniqueness and comparison principles for semilinear equations and inequalities in Carnot groups

Advances in Nonlinear Analysis, 2018
Variants of the Kato inequality are proved for distributional solutions of semilinear equations and inequalities on Carnot groups. Various applications to uniqueness, comparison of solutions and Liouville theorems are presented.

Comparison of Allergic Rhinitis Treatments on Utilities and Quality of Life: A MASK‐air Study

Clinical &Experimental Allergy, Volume 56, Issue 8, Page 904-913, August 2026.
This mHealth study has shown that fixed combinations of intranasal antihistamines and corticosteroids were associated with higher quality of life than oral antihistamines and intranasal antihistamines. Both intranasal corticosteroids and oral antihistamines were associated with higher quality of life than intranasal antihistamines.

Large sets at infinity and Maximum Principle on unbounded domains for a class of sub-elliptic operators

Bruno Pini Mathematical Analysis Seminar, 2019
Maximum Principles on unbounded domains play a crucial role in several problems related to linear second-order PDEs of elliptic and parabolic type. In the present notes, based on a joint work with prof. E.

Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, Volume 12, Issue 13, 6 July 2026.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.

Zeaxanthin‐Producing Winogradskyella schleiferi Strains

Journal of Basic Microbiology, Volume 66, Issue 7, July 2026.
ABSTRACT Two pigmented bacteria strains were isolated from the Mediterranean Sea. Phylogenetic analysis revealed that both strains are affiliated with Winograsdskyella schleiferi Z215. However, in contrast to this reference strain, they can assimilate additional carbon sources such as d‐mannose, l‐arabinose, d‐mannitol, and citrate.
