On Newton-Sobolev spaces
(Kossuth Lajos Tudomanyegyetem, 2017-01)
Newton-Sobolev spaces, as presented by N. Shanmugalingam, describe a way to extend Sobolev spaces to the metric setting via upper gradients, for metric spaces with ´sucient´ paths of nite length. Sometimes, as is the case ...
Muckenhoupt weights with singularities on closed lower dimensional sets in spaces of homogeneous type
We give sufficient conditions on a real number β and on a closed set F in a general space of homogeneous type (X,d,μ)(X,d,μ) in such a way that μ(B(x,d(x,F)))βμ(B(x,d(x,F)))β becomes a Muckenhoupt weight. In order to prove ...
Haarlet analysis of Lipschitz regularity in metric measure spaces
In this note we shall give a characterization of Lipschitz spaces on spaces of homogeneous type via Haar coefficients. © 2012 Science China Press and Springer-Verlag Berlin Heidelberg.

Homogeneous geodesics in pseudo-Riemannian nilmanifolds
(De Gruyter, 2016-04)
We study the geodesic orbit property for nilpotent Lie groups N when endowed with a pseudo-Riemannian left-invariant metric. We consider this property with respect to different groups acting by isometries. When N acts on ...

Larotonda spaces: Homogeneous spaces and conditional expectations
(World Scientific, 2016-02)
We define a Larotonda space as a quotient space P = UA/UB of the unitary groups of C ∗ -algebras 1 ∈ B ⊂ A with a faithful unital conditional expectation Φ : A → B. In particular, B is complemented in A, a fact which implies ...
On s-set in space of homogeneous type
(Polish Academy of Sciences. Institute of Mathematics, 2015-01)
Let (X, d, μ) be a space of homogeneous type. We study the relationship between two types of s-sets: relative to a distance and relative to a measure. We find a condition on a closed subset F of X under which F is an s-set ...
Le principe de Hasse pour les espaces homogènes: Réduction au cas des stabilisateurs finis
(Cambridge University Press, 2019)
For a large family of properties of homogeneous spaces, we prove that such a property holds for all homogeneous spaces of connected linear algebraic groups as soon as it holds for homogeneous spaces of SLn with finite ...
