Good projections of spaces of vector measures onto subspaces of Bochner integrable functions

open access: yes, 2004
We show that the complementability of L1(μ, X) in cabv(μ, X) implies the complementability of L1(μ, K(Z, X)) in cabv(μ, K(Z, X)), provided the projection from cabv(μ, X) onto L1(μ, X) is “good”, Z* is separable and K(

A dual mapping associated to a closed convex set and some subdifferential properties

open access: yes
In this paper, we establish some properties of the multivalued mapping (x, d) ⇒ DC (x; d) that associates to every element x of a linear normed space X the set of linear continuous functionals of norm d ≥ 0 and which separates the closed ball B (x; d ...

Epigraphical and Uniform Convergence of Convex Functions

open access: yes, 1995
. We examine when a sequence of lsc convex functions on a Banach space converges uniformly on bounded sets (resp. compact sets) provided it converges Attouch-Wets (resp. Painlev'e-Kuratowski). We also obtain related results for pointwise convergence

On non-surjective coarse isometries between Banach spaces

open access: yes, 2019
Assume that X; Y are real Banach spaces, Y has uniform convexity of type p (≥ 1), and f : X → Y is a standard coarse isometry. In this paper, we show that if∫ ∞      εf(S) 1/P                     __________ ds < ∞,    1      S1 + 1/pthen there is a ...

Convex Functions on "Sequentially Reflexive" Banach Spaces

open access: yes, 1995
. There is a sizeable class of results precisely relating boundedness, convergence and differentiability properties of continuous convex functions on Banach spaces to whether or not the space contains an isomorphic copy of ` 1 .

Characterizations of Banach Spaces via Convex and other Locally Lipschitz Functions

open access: yes, 1996
. Various properties of Banach spaces, including the reflexivity and the Schur property of a space, are characterized in terms of properties of corresponding classes of locally Lipschitz functions on those spaces. AMS Classification. 46A55, 46B20, 52A41.

Dunford-Pettis like properties on tensor products

open access: yes, 2018
In this paper we study equivalent formulations of the DP*Pp (1 < p < ∞). We show that X has the DP*Pp if and only if every weakly-p-Cauchy sequence in X is a limited subset of X.
