AbstractWe show that the recently discovered WILSONbases of exponential decay are unconditional bases for all modulation spaces onR, including the classical BESSELpotential spaces, the Segal algebraSo, and the SCHWARTZspace. As a consequence we obtain new bases for spaces of entire functions. On the other hand, the WILSONbases are no unconditional bases for the ordinaryLp‐spaces forp

AbstractDie Arbeit behandelt Quotienten einer komplexen Einheitskugel gerader Dimension, die sich als Zusammenhangskomponenten von SHIMURAvarietäten interpretieren lassen. Damit besitzen diese ein kanonisches Modell über einem Zahlkörper, das durch Angabe der speziellen Punkte und ihres Verhaltens unter der Wirkung von Automorphismen von C beschrieben wi

摘要:

AbstractSmooth points of the unit sphere of ORLICZspaces equipped with LUXEMBURGnorm are characterized for a non‐atomic measure as well as for the counting measure. As a corollary, a criterion of smoothness of ORLICZspaces with LUXEMBURGnorm is obtaine

摘要:

AbstractWe investigate conditions under which the completion of a product of CAUCHYspaces is equivalent to the product of the completions. Necessary and sufficient conditions are given for the WYLERcompletion to commute with products. The natural completion and natural ordered completion are shown to commute with finite products.

AbstractThere are investigated stationary randomq‐dimensional topological cell complexes in ℝd, in particular, random tessellations. General relationships between the mean values of topological characteristics are derived. Then they are specified for the casesd= 2, 3

摘要:

AbstractThis paper is concerned with continuity and differentiability of NEMYTSKIJoperators acting between spaces of summable abstract functions. In a first part, necessary and sufficient conditions for continuity are collected. Then main emphasis is given to sufficient conditions for differentiability in the sense of FRÉCHETand GÂTEAUX. Finally, second order differentiability is briefly discusse

AbstractIt is shown that derivations on LMC*‐algebras are always continuous and generate a continuous one‐parameter group of automorphisms. The structure of the derivation and the automorphism group on LMC*‐algebras is investi
