Name
-compact
Definition
a and b are infinite cardinal numbers.
A topological space X is called
-compact (or [a,b]-compact in the sense of complete accumulation points) provided that if E is an infinite subset of X and if |E| is a regular cardinal with
, then E has a complete accumulation point p in X (i.e., for every neighborhood U of p, we have
).
