Maximally localized Wannier functions for describing a topological phase transition in stanene
(American Physical Society, 2021-01)
Starting from first-principles calculations on pristine stanene and using maximally localized Wannier functions (MLWFs), we analyze the different phases of the system when it is driven to a topological phase transition. ...
Weak inequalities for maximal functions in Orlicz–Lorentz spaces and applications
(Academic Press Inc Elsevier Science, 2010-02)
Let 00, denote a net of intervals of the form (x-epsilon,x+epsilon) subset [0,alpha). Let f^{epsilon}(x) be any best constant approximation of f in Lambda_{w,phi´} on B(x,epsilon). Weak inequalities for maximal functions ...
SUPPORT OF MAXIMIZING MEASURES FOR TYPICAL C(0) DYNAMICS ON COMPACT MANIFOLDS
(AMER INST MATHEMATICAL SCIENCES, 2010)
Given a compact manifold X, a continuous function g : X -> IR, and a map T : X -> X, we study properties of the T-invariant Borel probability measures that maximize the integral of g. We show that if X is a n-dimensional ...
Composition of fractional Orlicz maximal operators and A1-weights on spaces of homogeneous type
(Springer Heidelberg, 2010-08)
For a Young function Θ with 0 ≤ α < 1, let Mα,Θ be the fractional Orlicz maximal operator defined in the context of the spaces of homogeneous type (X, d, μ) by Mα,Θf(x) = supx∈Bμ(B)α{double pipe}f{double pipe}Θ,B, where ...
Weighted modular estimates for a generalized maximal operator on spaces of homogeneous type
(Universidad de Barcelona, 2012-09)
We study weighted modular inequalities for a generalized maximal operator associated to a Young function in the context of spaces of homogeneous type. We prove the equivalence between these inequalities and a Dini-type ...
Pointwise estimate for the Hardy-Littlewood maximal operator on the orbits of contractive mappings
(Academic Press Inc Elsevier Science, 2012-11)
Let M n denote the Hardy-Littlewood maximal operator on the n-th iteration of a given iterated function system (IFS). We give sufficient conditions on the IFS in order to obtain a pointwise estimate for M n in terms of the ...
Invariant sets and Lyapunov pairs for differential inclusions with maximal monotone operators
(Academic Press Inc., 2018)
We give different conditions for the invariance of closed sets with respect to differential inclusions governed by a maximal monotone operator defined on Hilbert spaces, which is subject to a Lipschitz continuous perturbation ...
Composition of operators in Orlicz spaces
(Rocky Mt Math Consortium, 2008-12)
In this work we find sharp conditions for boundedness on Orlicz spaces of the composition of j operators, each one being of restricted weak type (p,p) for some p > 1, and of strong type (∞, ∞). Particularly, we find necessary ...
Inequalities in Lp−1 for the extended Lp best approximation operator
(Elsevier Inc, 2012-09)
The best polynomial approximation operator was recently extended by one of the authors from Lp to Lp−1. In this paper, we study weak and strong inequalities for maximal operators related with the extended best polynomial ...
