Baire Bijections of Extreme Points Generated by Small-Bound Isomorphisms of Simplex Spaces
We show that small-bound isomorphisms of spaces of affine continuous functions on Choquet simplices with Lindelof boundaries induce Baire measurable bijections of their sets of extreme points....

On the Banach-Mazur Distance Between Continuous Function Spaces with Scattered Boundaries
We study the dependence of the Banach-Mazur distance between two subspaces of vector-valued continuous functions on the scattered structure of their boundaries. In the spirit of a result of Y. Gordon (1970), we show that the constan...

An Amir-Cambern theorem for subspaces of Banach lattice-valued continuous functions
For i=1,2, let Ei be a reflexive Banach lattice over R with a certain parameter lambda+(Ei)>1, let Ki be a locally compact (Hausdorff) topological space and let Hi be a closed subspace of C0(Ki,Ei) such that each point of the Choquet boundary ChHi...

A converse to Amir-Lindenstrauss theorem in complex Banach spaces
We show that a complex Banach space is weakly Lindeloef determined if and only if the dual unit ball of any equivalent norm is weak* Valdivia compactum. We deduce that a complex Banach space X is weakly Lindeloef determined if and only if any nonsepa...

Cauchy´s stress theorem for stresses represented by measures
A version of Cauchy´s stress theorem is given in which the stress describing is represented by a tensor valued measure with weak divergence a vector valued measure. The system of forces is formalized in the notion ...

A weak vector-valued Banach-Stone theorem for Choquet simplices
We prove a more general vector-valued variant of the following statement: If X1 and X2 are Choquet simplices such that the spaces of affine continuous functions......
