We show that a Banach space is Hilbert if any only if its duality map maps line segments to convex sets.

## Abstract We present characterizations of the Besov spaces of generalized smoothness $ B^{\sigma,N}\_{p,q} $ (β^__n__^ ) via approximation and by means of differences. (Β© 2007 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
In this paper, we study the complete quantization of the homogeneous isotropic closed universe and prove that 1+1 dimensional quantum wormholes can be invested with a Hilbert-space structure, the inner product being naturally induced by the mini-superspace metric. The results indicate that the physi
## Abstract We study the local exactness of the \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\overline{\partial }$\end{document} operator in the Hilbert space __l__^2^ for a particular class of (0, 1)βforms Ο of the type \documentclass{article}\usepackage{amssymb}\be
## Abstract Let __X__ be a space of homogeneous type. The authors introduce some generalized approximations to the identity (for short, GAI) with optimal decay conditions in the sense that these conditions are the sufficient and necessary conditions for these GAI's to characterize BMO(__X__), the s
## Abstract We consider a class of measures called autophage which was introduced and studied by Szekely for measures on the real line. We show that the autophage measures on finiteβdimensional vector spaces over real or **Q**~__p__~ are infinitely divisible without nontrivial idempotent factors an
