Almost periodic functions / Besicovitch, Abram Samoilovitch

Public ISBD Titre : Almost periodic functions Type de document : texte imprimé Auteurs : Besicovitch, Abram Samoilovitch, Auteur Editeur : New York : Dover publications Année de publication : 1954 Importance : XIII-180 p. Format : 20 cm Note générale : Bibliogr. p. [179]-180. Index Langues : Anglais (eng) Mots-clés : Almost  periodic  functions Fourier  series Harmonic  analysis Index. décimale : 517.5 Théorie des fonctions Résumé : The first portion of this book establishes theorems of uniformly a. p. functions, including Bohr's original work, and de la Vallée Poussin's ingenious short proof based on classical theory of purely periodic functions. It considers such matters as summation of Fourier series of u.a.p functions by partial sums, the brochner-Fejer summation of u.a.p. functions, particular cases of Fourier series, and u.a.p. functions of two variables. The second portion of this work covers generalizations and extensions of the original theory, discussing relaxation of continuity restriction, auxiliary theorems and formulae, the Parseval equation and the Riesc-Fischer theorem, and similar matters. The third chapter discusses analytic a.p. functions, including results. Note de contenu : In summary : 1. Uniformly almost periodic functiond 2. Generalisation of almost periodic functions 3.
