Differentiability and ApproximateDifferentiability for Intrinsic LipschitzFunctions in Carnot Groups and a RademacherTheorem

open access: yesAnalysis and Geometry in Metric Spaces, 2014
A Carnot group G is a connected, simply connected, nilpotent Lie group with stratified Lie algebra.We study intrinsic Lipschitz graphs and intrinsic differentiable graphs within Carnot groups.

Conformality and Q-harmonicity in Carnot groups

open access: yesDuke Mathematical Journal, 2006
The main theorem of this paper is that 1-quasiconformal maps are smooth in all Carnot groups. This theorem can be used to prove rigidity theorems for quasiconformal maps between open subsets in certain classes of groups without any a priori smoothness assumption.

Geometric inequalities in Carnot groups [PDF]

open access: yes, 2012
Let $\GG$ 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.

Identifying 1-rectifiable measures in Carnot groups

open access: yesAnalysis and Geometry in Metric Spaces, 2023
We continue to develop a program in geometric measure theory that seeks to identify how measures in a space interact with canonical families of sets in the space. In particular, extending a theorem of M. Badger and R.

BiLipschitz Decomposition of Lipschitz Maps between Carnot Groups

open access: yesAnalysis and Geometry in Metric Spaces, 2015
Let f : G → H be a Lipschitz map between two Carnot groups. We show that if B is a ball of G, then there exists a subset Z ⊂ B, whose image in H under f has small Hausdorff content, such that B\Z can be decomposed into a controlled number of pieces, the ...

On criticality coupled sub-Laplacian systems with Hardy type potentials on Stratified Lie groups

open access: yesCommunications in Analysis and Mechanics, 2023
In this work, our main concern is to study the existence and multiplicity of solutions for the following sub-elliptic system with Hardy type potentials and multiple critical exponents on Carnot group $ \begin{equation*} \left\{\begin{aligned} & ...

On the Lie Algebra of polarizable Carnot groups [PDF]

open access: yesAnalysis and Mathematical Physics, 2020
Let \(G\) be a Carnot group equipped with a left-invariant sub-Riemannian metric, induced by an inner product \(\langle \cdot, \cdot \rangle\) on the first layer of its Lie algebra \(\mathfrak{g}\). The metric induces a family of \(p\)-sub-Laplacians \(\Delta_p\) on \(G\), where \(\Delta_2\) is the usual sub-Laplacian. Following [\textit{Z. M.

Harnessing Colloidal Dispersion for Laccase‐Driven Enzymatic Depolymerization of Polystyrene

open access: yesAngewandte Chemie, EarlyView.
Polystyrene (PS), long considered non‐degradable by biocatalytic pathways, can now be broken down under aqueous conditions using atmospheric air and a laccase–mediator system composed of a commercially available fungal enzyme and 1‐hydroxybenzotriazole as small organic mediator.
