A look at BMOφ(ω) through Carleson measures
(Birkhauser Verlag Ag, 2007-06)
As Fefferman and Stein showed, there is a tight connection between Carleson measures and BMO functions. In this work we extend this type of results to the more general scope of the BMOϕ(ω) spaces. As a byproduct a weighted ...
Wavelet expansions for weighted, vector-valued BMO functions
(Springer, 2010-03)
We introduce a scale of weighted Carleson norms, which depend on an integrability parameter p, where p = 2 corresponds to the classical Carleson measure condition. Relations between the weighted BMO norm of a vector-valued ...
Dynamical sampling
(Academic Press Inc Elsevier Science, 2017-05)
Let Y={f(i),Af(i),…,Ali f(i):i∈Ω}, where A is a bounded operator on ℓ2(I). The problem under consideration is to find necessary and sufficient conditions on A,Ω,{li:i∈Ω} in order to recover any f∈ℓ2(I) from the measurements ...
A generalization of Toeplitz operators on the Bergman space
(Theta Foundation, 2015-08)
If μ μ is a finite measure on the unit disc and k ⩾ 0 k⩾0 is an integer, we study a generalization derived from Engli\v{s}'s work, T ( k ) μ Tμ(k), of the traditional Toeplitz operators on the Bergman space \berg \berg, ...
THE MAXIMAL ENTROPY MEASURE DETECTS NON-UNIFORM HYPERBOLICITY
(INT PRESS BOSTON, INC, 2010)
We characterize two of the most studied non-uniform hyperbolicity conditions for rational maps, semi-hyperbolicity and the topological Collet-Eckmann condition, in terms of the maximal entropy measure.
Meromorphic and Harmonic Functions Inducing Continuous Maps from MH∞ into the Riemann Sphere
(Academic Press Inc Elsevier Science, 2001-06)
We study the class of maps from the open unit disk into the Riemann sphere or into [−∞, +∞] that can be continuously extended to the maximal ideal space of H∞. Several characterizations are given for these classes and the ...
