Multiplier Theorems on Anisotropic Hardy Spaces

Wang, Li-An, Wang, Li-An January 2012 (has links)
We extend the theory of singular integral operators and multiplier theorems to the setting of anisotropic Hardy spaces. We first develop the theory of singular integral operators of convolution type in the anisotropic setting and provide a molecular decomposition on Hardy spaces that will help facilitate the study of these operators. We extend two multiplier theorems, the first by Taibleson and Weiss and the second by Baernstein and Sawyer, to the anisotropic setting. Lastly, we characterize the Fourier transforms of Hardy spaces and show that all multipliers are necessarily continuous.

Spectral Theory Of Composition Operators On Hardy Spaces Of The Unit Disc And Of The Upper Half-plane

Gul, Ugur 01 February 2007 (has links) (PDF)
In this thesis we study the essential spectrum of composition operators on the Hardy space of the unit disc and of the upper half-plane. Our starting point is the spectral analysis of the composition operators induced by translations of the upper half-plane. We completely characterize the essential spectrum of a class of composition operators that are induced by perturbations of translations

Hardy Spaces On Hyperconvex Domains

Alan, Muhammed Ali 01 January 2003 (has links) (PDF)
In this thesis, we give a new definition of Hardy Spaces on hyperconvex domains in terms of Monge-Amp`ere measures which unifies the Hardy spaces on polydiscs and balls. Also we survey Monge-Amp`ere operators and Monge- Amp`ere measures.

Linear Extremal Problems in the Hardy Space <i>H<sup>p</sup></i> for 0 < <i>p</i> < 1

Connelly, Robert Christopher 23 March 2017 (has links)
In this thesis, we consider linear extremal problems in the Hp spaces. For many of these extremal problems, a unique solution can be guaranteed. We will examine some of the classical examples of extremal problems in these spaces. With this framework in place we will then consider a particular problem which does not always have a unique solution.

No. of bitstreams: 1 Bertoloto_FabioJose_D.pdf: 716013 bytes, checksum: 13487be60bd9cd099898dc66a1234a32 (MD5) Previous issue date: 2009 / Resumo: Neste trabalho, estudamos os já conhecidos espaços de Hardy de funções holomorfas Hp(Delta; F), 1 = p = 8. Estudamos também os espaços de Banach com as propriedades RNP e ARNP e os espaços UMD. Tendo introduzido estes, a partir de resultados voltados para o caso complexo dos artigos de Taylor [36], [37], que demonstram que (Hp(Delta ))' e Hq(Delta ) são canonicamente topologicamente isomorfos para 1 < p < 8, com q conjugado de p, demonstramos que sob as condições de F e F' terem a propridade ARNP, (Hp(Delta ; F))' e Hq(Delta ; F') são canonicamente topologicamente isomorfos (para 1 < p, q < 8, 1/p + 1 /q = 1) se, e somente se, F é UMD / Abstract: In this work we study the vector-valued Hardy spaces Hp(Delta ; F) (1 = p = 8). We also study the Banach spaces with the properties ARNP and RNP and the UMD spaces. We also study the Banach spaces with the RNP and ARNP properties, and also the UMD spaces. By following the approach of Taylor [36],[37] in the scalar-valued case, we prove that, when F and F' have the ARNP property, when (Hp(Delta ; F))' and Hq(Delta ; F) are canonically topologically isomorphic (for 1 < p, q < 8, 1/ p + 1/ q = 1) if and only if F is UMD / Doutorado / Analise Funcional / Doutor em Matemática
