On Decoupling in Banach Spaces [PDF]
Journal of Theoretical Probability, 2021 AbstractWe consider decoupling inequalities for random variables taking values in a Banach space X. We restrict the class of distributions that appear as conditional distributions while decoupling and show that each adapted process can be approximated by a Haar-type expansion in which only the pre-specified conditional distributions appear.

International Journal of Mathematics and Mathematical Sciences, 1991 In recent publications the concepts of fast completeness and local barreledness have been shown to be related to the property of all weak‐* bounded subsets of the dual (of a locally convex space) being strongly bounded. In this paper we clarify those relationships, as well as giving several different characterizations of this property.

Skewness in Banach spaces [PDF]
Transactions of the American Mathematical Society, 1983 Let E E be a Banach space. One often wants to measure how far E E is from being a Hilbert space. In this paper we define the skewness s ( E ) s(E) of a Banach space E E , 0 ⩽ s ( E ) ⩽ 2

On Nonseparable Banach Spaces [PDF]
Transactions of the American Mathematical Society, 1982 Combining combinatorial methods from set theory with the functional structure of certain Banach spaces we get some results on the isomorphic structure of nonseparable Banach spaces. The conclusions of the paper, in conjunction with already known results, give complete answers to problems of the theory of Banach spaces. An interesting point here is that

Advances in Mathematics, 2005 We show that any Banach space contains a continuum of non isomorphic subspaces or a minimal subspace. We define an ergodic Banach space $X$ as a space such that $E_0$ Borel reduces to isomorphism on the set of subspaces of $X$, and show that every Banach space is either ergodic or contains a subspace with an unconditional basis $ which is ...

On incomparability of Banach spaces [PDF]
Mathematische Zeitschrift, 1986 We give a simpler proof of the well-known \textit{H. P. Rosenthal}'s characterization of totally incomparable Banach spaces [J. Funct. Anal. 4, 167-175 (1969; Zbl 0181.154)] and we introduce a dual concept of incomparability: Two Banach spaces are said to be totally coincomparable if they have no isomorphic quotients of infinite-dimension.

Journal of Functional Analysis, 1991 Building on the work of Grothendieck on tensor products and Fredholm determinants, the authors develop a theory of relative Pfaffians for operators (resp. bilinear forms) on Banach spaces. In the finite dimensional case, the relative Pfaffian of two skew-symmetric \(2k\times 2k\) matrices \(A\) and \(B\) (\(A\) being invertible) is defined to be ...

On the spaces of mappings on Banach spaces [PDF]
Journal of the Australian Mathematical Society, 1967 Let E be a real Banach space. A mapping f of E into E is said to be bounded if f maps every bounded set into a bounded set.

The (𝐷) Property in Banach Spaces
Abstract and Applied Analysis, 2012 A Banach space 𝐸 is said to have (D) property if every bounded linear operator 𝑇∶𝐹→𝐸∗ is weakly compact for every Banach space 𝐹 whose dual does not contain an isomorphic copy of 𝑙∞.

Local Uniform Kadec-Klee Property (LUKK) and Modulus of (LUKK)
Journal of Function Spaces, 2020 A new geometry property and two new moduli are introduced in Banach space. First, the concept of local uniform Kadec-Klee property (LUKK) is introduced and the implication relationships between LUKK and local near uniform convexity LNUC, uniformly Kadec ...
