چکیده
We prove that every normal non-compact space which is nowhere of cardinality at most c has an ω-far point. This provides a partial answer to a question of van Douwen. 2002 Elsevier Science B.V. All rights reserved. MSC: 54B15; 54D80; 03E55

REMOTAL CENTERS AND CHEBYSHEV CENITERS IN NORMED SPACES
In this paper, we consider Nearest points" and Farthestpoints" in normed linear spaces. For normed space (X; ∥:∥), the set W subset X,we dene Pg; Fg;Rg where g 2 W. We obtion results about on Pg; Fg;Rg. Wend new results on Chebyshev centers in normed spaces. In nally we deneremotal center in normed spaces.
متن کاملPlanar and affine spaces
In this note, we characterize finite 3-dimensional affine spaces as the only linear spaces endowed with set Ω of proper subspaces having the properties (1) every line contains a constant number of points, say n, with n > 2; (2) every triple of noncollinear points is contained in a unique member of Ω; (3) being disjoint is an equivalence relation in Ω with the additional property that every equi...
متن کاملOrbits of Turning Points for Maps of Finite Graphs and Inverse Limit Spaces
In this paper we examine the topology of inverse limit spaces generated by maps of finite graphs. In particular we explore the way in which the structure of the orbits of the turning points affects the inverse limit. We show that if f has finitely many turning points each on a finite orbit then the inverse limit of f is determined by the number of elements in the ω-limit set of each turning poi...
متن کاملUltrafilter Spaces on the Semilattice of Partitions
The Stone-Čech compactification of the natural numbers βω (or equivalently, the space of ultrafilters on the subsets of ω) is a well-studied space with interesting properties. Replacing the subsets of ω by partitions of ω in the construction of the ultrafilter space gives non-homeomorphic spaces of partition ultrafilters corresponding to βω. We develop a general framework for spaces of this typ...
متن کاملORTHOGONALITY AND SMOOTH POINTS IN C ( K ) AND C b ( Ω )
For the usual norm on spaces C(K) and C b (Ω) of all continuous functions on a compact Hausdorff space K (all bounded continuous functions on a locally compact Hausdorff space Ω), the following equalities are proved: lim t→0+ ||f + tg|| C(K) − ||f || C(K) t = max x∈{z | |f (z)|=||f ||} Re(e −i arg f (x) g(x)). and lim t→0+ ||f + tg|| C b (Ω) − ||f || C b (Ω) t = inf δ>0 sup x∈{z | |f (z)|≥||f |...
