Stochastic Operators and Extreme Points

Concerning weak ∗ - extreme points

Every separable nonreflexive Banach space admits an equivalent norm such that the set of the weak-extreme points of the unit ball is discrete.

On Extreme Averaging Operators

points and convergent process operators

We present a strategy for nding algebraic correctness proofs for communication systems. It is described in the setting of CRL 11], which is, roughly, ACP 2, 3] extended with a formal treatment of the interaction between data and processes. The strategy has already been applied successfully in 4] and 10], but was not explicitly identiied as such. Moreover, the protocols that were veriied in thes...

On the Extreme Points and Strongly Extreme Points in Köthe–bochner Spaces

We give the necessary conditions of extreme points and strongly extreme points in the unit ball of Köthe–Bochner spaces. The conditions have been shown to be sufficient earlier.

Extreme Points of Vector Functions

Several previous investigations have appeared in the literature which discuss the nature of the set T in »-dimensional space spanned by the vectors ifsdui, ■ ■ ■ , fsdp.n) where 5 ranges over all measurable sets. It was first shown by Liapounov that xi ui, • • ■ , un are atomless measures, then the set F is convex and closed. Extensions of this result were achieved by D. Blackwell [l] and Dvore...
