Maps Having the Bula Property
Every open continuous map f from a space X onto a paracompact C-space Y admits two disjoint closed sets F0, F1 ⊂ X , with f(F0) = Y = f(F1), provided all fibers of f are infinite and C∗-embedded in X . Applications are demonstrated for the existence of “disjoint” usco multiselections of set-valued l.s.c. mappings defined on paracompact C-spaces, and for special type of factorizations of open co...
متن کاملOn the Hahn-banach Extension Property
A self-contained and brief proof is given of the equivalence of the Hahn-Banach extension property (HB) and the conditional order completeness of the range space (LUB). Various other equivalences are discussed.
متن کاملOn the Density Property of Psc Fields
Let S be a nite set of nite and real local primes of a eld K. We prove two results. First, a PAC eld over K is already PAC over each nonempty S-open subset of K; if K is global, this implies that it also PAC over each separable Hilbert subset of K. Second, each PSC eld inside K tot;S has the S-density property.
متن کاملOn general matrices having the Perron-Frobenius Property
A matrix is said to have the Perron-Frobenius property if its spectral radius is an eigenvalue with a corresponding nonnegative eigenvector. Matrices having this and similar properties are studied in this paper as generalizations of nonnegative matrices. Sets consisting of such generalized nonnegative matrices are studied and certain topological aspects such as connectedness and closure are pro...
