Perron-Frobenius operators and the Klein-Gordon equation
(European Mathematical Society, 2014)
For a smooth curve Γ and a set Λ in the plane R2, let AC(Γ; Λ) be the space of finite Borel measures in the plane supported on Γ, absolutely continuous with respect to the arc length and whose Fourier transform vanishes ...

End-point estimates for iterated commutators of multilinear singular integrals
(London Mathematical Society, 2014-02)
Iterated commutators of multilinear Calder´on-Zygmund operators and pointwise multiplication with functions in BMO are studied in products of Lebesgue spaces. Both strong type and weak end-point estimates are obtained, ...

Firmly nonexpansive mappings in classes of geodesic spaces
(American Mathematical Society, 2014)
Firmly nonexpansive mappings play an important role in metric fixed point theory and optimization due to their correspondence with maximal monotone operators. In this paper we do a thorough study of fixed point theory and ...

Weighted inequalities and multiparameter harmonic analysis
(2014-04-30)
El tema central de esta tesis es el estudio de desigualdades con pesos para algunos de los operadores clásicos del análisis armónico. De entre estos operadores, los que más nos interesan, son aquellos que son invariantes ...

An overview on the Prus-Szczepanik condition
(SpringerOpen, 2014-12)
In 2005 Prus and Sczcepanik introduced a large class of Banach spaces with the fixed point property for nonexpansive mappings. We say that this class satisfies the PSz condition. Checking that a given Banach space belongs ...

Linear subsets of nonlinear sets in topological vector spaces
(American Mathematical Society, 2014-01)
For the last decade there has been a generalized trend in Mathematics on the search for large algebraic structures (linear spaces, closed subspaces, or infinitely generated algebras) composed of mathematical objects enjoying ...

A local spectral condition for strong compactness with some applications to bilateral weighted shifts
(American Mathematical Society, 2014-01)
An algebra of bounded linear operators on a Banach space is said to be strongly compact if its unit ball is precompact in the strong operator topology, and a bounded linear operator on a Banach space is said to be strongly ...

Sharp weighted estimates for dyadic shifts and the A2 conjecture
(De Gruyter, 2014-02)
We give a self-contained proof of the A2 conjecture, which claims that the norm of any Calderón–Zygmund operator is bounded by the first degree of the A2 norm of the weight. The original proof of this result by the first ...
