$C\sb{11}$ contractions are reflexive

A non-reflexive Banach space with all contractions mean ergodic

We construct on any quasi-reflexive of order 1 separable real Banach space an equivalent norm, such that all contractions on the space and all contractions on its dual are mean ergodic, thus answering negatively a question of Louis Sucheston.

Uniformly convex Banach spaces are reflexive - constructively

We propose a natural definition of what it means in a constructive context for a Banach space to be reflexive, and then prove a constructive counterpart of the MilmanPettis theorem that uniformly convex Banach spaces are reflexive. Our aim in this note is to present a fully constructive analysis of the Milman-Pettis theorem [11, 12, 9, 13]: a uniformly convex Banach space is reflexive. First, t...

Piecewise Contractions Are Asymptotically Periodic

We show that, given a finite partition of the plane C such that the map G acts as a linear contraction on each part, for almost every choice of parameters every orbit of G is (asymptotically) periodic.

CONTRACTIONS DUE TO α-ADRENOCEPTOR AGONISTS ARE MEDIATED BY α1-ADRENOCEPTORS IN RAT CAROTID ARTERY

Some large vessels have a mixed functional population of postjunctional α1- and α 2-adrenoceptors. The purpose of the work presented here was to investigate the population of postjunctional α -adrenoceptors in the rat isolated common carotid artelY Male Wi star rats were killed by overdose with pentobarbitone sodium, after which the left and right common carotid arteries were removed. Rings...
