Two cardinal inequalities for functionally Hausdorff spaces
In this paper, two cardinal inequalities for functionally Hausdorff spaces are established. A bound on the cardinality of the τθ-closed hull of a subset of a functionally Hausdorff space is given. Moreover, the following theorem is proved: ifX is a functionally Hausdorff space, then |X| ≤ 2χ(X)wcd(X).

translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولSome Strengthenings of the Ulam Nonmeasurability Condition
The purpose of this paper is to amplify the remarks made in the footnote on p. 603 in [4]. A complete account of the investigation initiated in [4] will be published in Fundamenta Mathematicae; in this paper we shall discuss various strengthenings of the Ulam nonmeasurability condition as well as their relative strength. Some of the present results were announced in [6]. We shall assume the fam...

15 صفحه اولA Cardinal Function Algorithm for Computing Multivariate Quadrature Points
We present a new algorithm for numerically computing quadrature formulas for arbi-trary domains which exactly integrate a given polynomial space. An effective method for constructingquadrature formulas has been to numerically solve a nonlinear set of equations for the quadraturepoints and their associated weights. Symmetry conditions are often used to reduce the number ofequatio...
