Set Theory and Metric Spaces
Proof: Any open ball is an open set (Theorem 27), so by Theorem 28 a union of
open balls is open. Conversely, let U be open. For any x in U we have that a
suitable S,(x) is contained in U. Evidently U is the union of all these S,(x)'s.
Remark: In ...

Neighbourhoods, Interior and Accumulation Points (2.1) Definition: Let (X; 3) be a
topological space, XQ e X and N c X. Then N is said to be a neighbourhood of x0

Elements of Operator Theory
A subset V of a metric space X is closed in X if its complement X\ V is an open set
in X. Theorem 3.22. If X is a metric space, then (a) the whole set X and the empty
set 0 are closed, (b) the union of a finite collection of closed sets is closed, ...

(Semi-Open Set etc.) 1. 6-closed and 5-closed sets A subset A of a topological
space (X, 1) is called regular open if A : Int(Cl(A)). The complement of a regular

If Q is an open set in Y, then 0 : f-1(Q) is an open set in X. Therefore 0 is the union
of some sets Beg and so Q =f(O) is a union of some of the sets f(B) ef(§?). Hence
is a base for the topology on Y. Now let us suppose that is a base for Y. Then ...
