Infinite-Dimensional Carnot Groups and Gâteaux Differentiability
The article under review contributes to research based around Rademacher's theorem, which states that a Lipschitz mapping between two Euclidean spaces is differentiable almost everywhere with respect to the Lebesgue measure. More specifically, the article joins a flourishing branch of research which has the broad aim of extending Rademacher's theorem ...

We present a unified and concise method for establishing L p $L^{p}$ Hardy and Rellich inequalities for a broad class of subelliptic operators of divergence type.

Measure contraction properties of Carnot groups
International audienceWe prove that any corank 1 Carnot group of dimension k + 1 equipped with a left-invariant measure satisfies the MCP(K, N) if and only if K ≤ 0 and N ≥ k + 3. This generalizes the well known result by Juillet for the Heisenberg group

Local Monotonicity and Isoperimetric Inequality on Hypersurfaces in Carnot groups
Let G be a k-step Carnot group of homogeneous dimension Q. Later on we shall present some of the results recently obtained in [32] and, in particular, an intrinsic isoperimetric inequality for a C2-smooth compact hypersurface S with boundary @S.

Optimizing a machine learning design of dielectric properties in lead-free piezoelectric ceramics
Designing lead-free piezoelectric ceramics with tailored electrical properties remains a critical challenge for various applications. In this paper we present a novel methodology integrating Machine Learning (ML) and optimization procedures to fine-tune ...

Geometric inequalities in Carnot groups
Let G be a sub-Riemannian k-step Carnot group of homogeneous dimension Q. In this paper, we shall prove several geometric inequalities concerning smooth hypersurfaces (i.e.

A note on the inverse maximum principle on Carnot groups [PDF]
Let ΔG be a sublaplacian on a Carnot group, and let μ be a local measure on the open set Ω ⊂ G. If u ∈ L1l oc(Ω) is such that −ΔGu = μ, u ≥ 0 on Ω, then μc ≥ 0, where μc is the concentrated component of μ with respect to the G-capacity.

The p-Laplace equation in a class of Hormander vector fields
We find the fundamental solution to the p-Laplace equation in a class of Hormander vector fields that generate neither a Carnot group nor a Grushin-type space. The singularity occurs at the sub-Riemannian points, which naturally corresponds to finding

Performance of plant-produced RBDs as SARS-CoV-2 diagnostic reagents: a tale of two plant platforms
The COVID-19 pandemic has underscored the need for rapid and cost-effective diagnostic tools. Serological tests, particularly those measuring antibodies targeting the receptor-binding domain (RBD) of the virus, play a pivotal role in tracking infection ...

Sharp measure contraction property for generalized H-type Carnot groups
International audienceWe prove that H-type Carnot groups of rank k and dimension n satisfy the MCP(K, N) if and only if K ≤ 0 and N ≥ k + 3(n − k). The latter integer coincides with the geodesic dimension of the Carnot group.
