Unextendable Intrinsic Lipschitz Curves: [PDF]

open access: yesANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2021
In the setting of Carnot groups, we exhibit examples of intrinisc Lipschitz curves of positive H1measure that intersect every connected intrinsic Lipschitz curve in a H1-negligible set.

On the Hermitian structures of the sequence of tangent bundles of an affine manifold endowed with a Riemannian metric

open access: yesComplex Manifolds, 2022
Let (M, ∇, 〈, 〉) be a manifold endowed with a flat torsionless connection r and a Riemannian metric 〈, 〉 and (TkM)k≥1 the sequence of tangent bundles given by TkM = T(Tk−1M) and T1M = TM. We show that, for any k ≥ 1, TkM carries a Hermitian structure (Jk,

On Degenerate 3-(α, δ)-Sasakian Manifolds

open access: yesComplex Manifolds, 2022
We propose a new method to construct degenerate 3-(α, δ)-Sasakian manifolds as fiber products of Boothby-Wang bundles over hyperkähler manifolds. Subsequently, we study homogeneous degenerate 3-(α, δ)-Sasakian manifolds and prove that no non-trivial ...

Weighted CBMO estimates for commutators of matrix Hausdorff operator on the Heisenberg group

open access: yesOpen Mathematics, 2020
In this article, we study the commutators of Hausdorff operators and establish their boundedness on the weighted Herz spaces in the setting of the Heisenberg group.

Locally conformally Kähler structures on four-dimensional solvable Lie algebras

open access: yesComplex Manifolds, 2019
We classify and investigate locally conformally Kähler structures on four-dimensional solvable Lie algebras up to linear equivalence. As an application we can produce many examples in higher dimension, here including lcK structures on Oeljeklaus-Toma ...

On theorems of Morgan and Cowling-Price for selected nilpotent Lie groups

open access: yesMathematical Inequalities & Applications, 2019
Let G be a connected, simply connected nilpotent Lie group. For p,q ∈ [1,+∞] , the Lp −Lq analogue of Morgan’s theorem was proved only for two step nilpotent Lie groups.

Complex structures on the complexification of a real Lie algebra

open access: yesComplex Manifolds, 2018
Let g = a+b be a Lie algebra with a direct sum decomposition such that a and b are Lie subalgebras. Then, we can construct an integrable complex structure J̃ on h = ℝ(gℂ) from the decomposition, where ℝ(gℂ) is a real Lie algebra obtained from gℂby the ...

A COUNTEREXAMPLE TO METRIC DIFFERENTIABILITY

open access: yesProceedings of the Edinburgh Mathematical Society, 2003
We show that the metric version of Pansu’s differentiability result for Lipschitz maps fails; this illustrates an interesting difference between Euclidean domains and domains that are non-abelian stratified groups.

Effect of dietary supplementation with ultramicronized palmitoylethanolamide in maintaining remission in cats with nonflea hypersensitivity dermatitis: a double‐blind, multicentre, randomized, placebo‐controlled study

open access: yesVeterinary Dermatology, Volume 30, Issue 5, Page 387-e117, October 2019., 2019
Background – Feline nonflea hypersensitivity dermatitis (NFHD) is a frequent cause of over‐grooming, scratching and skin lesions. Multimodal therapy often is necessary. Hypothesis/Objectives – To investigate the efficacy of ultramicronized palmitoylethanolamide (PEA‐um) in maintaining methylprednisolone‐induced remission in NFHD cats.

Isometry Lie algebras of indefinite homogeneous spaces of finite volume

open access: yesProceedings of the London Mathematical Society, Volume 119, Issue 4, Page 1115-1148, October 2019., 2019
Abstract Let g be a real finite‐dimensional Lie algebra equipped with a symmetric bilinear form ⟨·,·⟩. We assume that ⟨·,·⟩ is nil‐invariant. This means that every nilpotent operator in the smallest algebraic Lie subalgebra of endomorphisms containing the adjoint representation of g is an infinitesimal isometry for ⟨·,·⟩.
