On Fixed Point Property under Lipschitz and Uniform Embeddings

open access: yesJournal of Function Spaces, Volume 2018, Issue 1, 2018., 2018
We first present a generalization of ω⁎‐Gâteaux differentiability theorems of Lipschitz mappings from open sets to those closed convex sets admitting nonsupport points and then show that every nonempty bounded closed convex subset of a Banach space has the fixed point property for isometries if it Lipschitz embeds into a super reflexive space. With the

Weakly Compact Generating and Shrinking Markusevic Bases [PDF]

open access: yes, 2006
2000 Mathematics Subject Classification: 46B30, 46B03.It is shown that most of the well known classes of nonseparable Banach spaces related to the weakly compact generating can be characterized by elementary properties of the closure of the coefficient ...

A Characterization of Weakly Lindelöf Determined Banach Spaces [PDF]

open access: yes, 2003
2000 Mathematics Subject Classification: 46B26, 46B03, 46B04.We prove that a Banach space X is weakly Lindelöf determined if (and only if) each non-separable Banach space isomorphic to a complemented subspace of X has a projectional resolution of the ...

The UMD Constants of the Summation Operators

open access: yes, 2004
The UMD property of a Banach space is one of the most useful properties when one thinks about possible applications. This is in particular due to the boundedness of the vector-valued Hilbert transform for functions with values in such a space. Looking at

A note on subsymmetric renormings of Banach spaces

open access: yesQuaestiones Mathematicae, 2018
We revisit the concept of a subsymmetric norm and construct a subsymmetric renorming of a Banach space with a subsymmetric basis. As a by-product of our work we introduce the concept of a lower symmetric basis and investigate its connection with ...
