Approximating Sequences and Bidual Projections

چکیده
SINCE the appearance of Enflo's negative solution to the approximation problem [3], only a few positive general results on the approximation properties have been obtained. However, it is shown in [2] that any separable Banach space with the metric approximation property (M.A.P.) has the commuting metric approximation property. More precisely, if X has (MAP) there exists a sequence {Rn} of finite rank operators such that

Bidual Horn Functions and Extensions
Partially defined Boolean functions (pdBf) , where are disjoint sets of true and false vectors, generalize total Boolean functions by allowing that the function values on some input vectors are unknown. The main issue with pdBfs is the extension problem, which is deciding, given a pdBf, whether it is interpolated by a function from a given class of total Boolean functions, and computing a formu...
متن کاملClosed Tripotents and Weak Compactness in the Dual Space of a Jb*-triple
We revise the concept of compact tripotent in the bidual space of a JB*-triple. This concept was introduced by Edwards and Rüttimann generalizing the ideas developed by Akemann for compact projections in the bidual of a C*-algebra. We also obtain some characterizations of weak compactness in the dual space of a JC*-triple, showing that a bounded subset in the dual space of a JC*-triple is relat...
متن کاملDomains with Approximating Projections
We investigate approximating posets with projections (approximating pop's). These are triples (D; ; P) consisting of a poset (D;) and a directed set P of projections with sup P = id D. They carry a canonical uniformity and thus a topology. We relate their properties such as completeness and compactness to properties of the poset and the projection set. We show that each monotone net in D is con...
متن کاملConnes-amenability of bidual and weighted semigroup algebras
We investigate the notion of Connes-amenability, introduced by Runde in [14], for bidual algebras and weighted semigroup algebras. We provide some simplifications to the notion of a σWC-virtual diagonal, as introduced in [10], especially in the case of the bidual of an Arens regular Banach algebra. We apply these results to discrete, weighted, weakly cancellative semigroup algebras, showing tha...
متن کاملRecognition and dualization of disguised bidual Horn functions
We consider the problem of dualizing a Boolean function f given by CNF, i.e., computing a CNF for its dual f. While this problem is not solvable in quasi-polynomial total time in general (unless SAT is solvable in quasi-polynomial time), it is so in case the input belongs to special classes, e.g., the class of bidual Horn CNF φ [9] (i.e., both φ and its dual φ represent Horn functions). In this...
