k-β and k-Nearly Uniformly Convex Banach Spaces
vol. 162, No. 2, 1991 k-β and k-Nearly Uniformly Convex Banach Spaces Denka Kutzarova Different uniform geometrical properties have been defined between the uniform convexity and the reflexivity of Banach spaces. In the present paper we introduce other properties of this type, namely k-β and k-nearly uniform convexity. The definitions, as well as some of the results presented here, are announce...
متن کاملOn Uniformly Approximable Sidon Sets
Let G be a compact abelian group and let T be the character group of G. Suppose £ is a subset of T. A trigonometric polynomial f on G is said to be an ^-polynomial if its Fourier transform / vanishes off E. The set E is said to be a Sidon set if there is a positive number B such that 2^xeb |/(X)| á-B||/||u for all E-polynomials /; here, ||/||„ = sup{ |/(x)| : xEG}. In this note we shall discuss...
متن کاملOn Gaussian Marginals of Uniformly Convex Bodies
We show that many uniformly convex bodies have Gaussian marginals in most directions in a strong sense, which takes into account the tails of the distributions. These include uniformly convex bodies with power type 2, and power type p > 2 with some additional type condition. In particular, all unit-balls of subspaces of Lp for 1 < p < ∞ have Gaussian marginals in this strong sense. Using the we...
متن کاملSome Uniformly Convex Spaces
size of the éliminants but the size of their largest prime factor which is important, and secondly it is not essential to take the w's in order of magnitude. In answer, it should be pointed out that after one passes the limits of factor tables, it becomes impracticable to deal with the factors of the éliminant rather than the éliminant. Therefore, since the éliminant (in one case at least) appe...
متن کاملOn Saturated Uniformly A-convex Algebras
Following ideas of A. C. Cochran, we give a suitable definition of a saturated uniformly A-convex algebra. In the m-convex case, such algebra is a uniform topological one.
