Discrete approximation of spaces of homogeneous type
(Springer, 2009-01)
In this note we combine the dyadic families introduced by M. Christ in (Colloq. Math. 60/61(2):601-628, 1990) and the discrete partitions introduced by J.M. Wu in (Proc. Am. Math. Soc. 126(5):1453-1459, 1998) to get ...
The index of symmetry of compact naturally reductive spaces
(Springer, 2014-08)
We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
Fractional order Orlicz-Sobolev spaces
(Academic Press Inc Elsevier Science, 2019-04)
In this paper we define the fractional order Orlicz-Sobolev spaces, and prove its convergence to the classical Orlicz-Sobolev spaces when the fractional parameter s↑1 in the spirit of the celebrated result of Bourgain-Br ...
Hardy space of translated Dirichlet series
(Springer, 2021-03)
We study the Hardy space of translated Dirichlet series H+. It consists on those Dirichlet series ∑ ann-s such that for some (equivalently, every) 1 ≤ p< ∞, the translation ∑ann-(s+1σ) belongs to the Hardy space Hp for ...
The fractional integral between Orlicz and BMO(phi) spaces on spaces of homogeneous type
(Faculty of Mathematics and Physics of Charles University, 2003-07)
In this work we give sufficient and necessary conditions for the boundednessof the fractional integral operator acting between weighted Orlicz spaces and suitableBMOφ spaces, in the general setting of spaces of homogeneous ...
World Images and The Time-Space Notions: From An Epistemological Point of View
(Paripex, 2014-02)
This paper propose to show the relevance of a reconsideration of the time-space notions, in order to make possible an epistemological analysis of the world images as an ontological component of theories. The argumentative ...
Some embedding theorems for Hörmander-Beurling spaces
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010-04-15)
In this paper we prove a number of results on sequence space representations and embedding theorems of Hörmander-Beurling spaces. As a consequence and using sharp results of Meise, Taylor and Vogt, a result of Kaballo on ...
Effect of row spacing on vegetative structure, fruit characteristics and oil productivity of N–S and E–W oriented olive hedgerows
(2015-09-22)
The effect of row spacing on fruit characteristics and production was studied in two super-high density olive hedgerow orchards planted at three row spacings (5.0, 4.0 and 2.5 m) with the same intra-row tree spacing, one ...
On a model for rotational tunneling with a C6 -space-time symmetric analog
(Springer, 2019-08)
We analyze the simple model of a rigid rotor with C3 symmetry and show that the use of parity simplifies considerably the calculation of its eigenvalues. We also consider a non-Hermitian space-time-symmetric counterpart ...
