    (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010-04-15) Motos, Joaquin; Jesus Planells, Maria; Villegas G, Jairo; Motos, Joaquin; Jesus Planells, Maria; Villegas G, Jairo; Universidad EAFIT. Departamento de Ciencias; Matemáticas y Aplicaciones
    In this paper we prove a number of results on sequence space representations and embedding theorems of Hörmander-Beurling spaces. As a consequence and using sharp results of Meise, Taylor and Vogt, a result of Kaballo on short sequences and hypoelliptic operators is extended to ?-hypoelliptic differential operators and to the vector-valued setting. © 2009 Elsevier Inc.
