## point-set topologyAlso known as general topology, a branch of topology
concerned with how to put a structure on a set in such a way as to generalize
the idea of continuity for maps from
the real numbers to itself. A topology on a set X is a certain
set of so-called open subsets of the set X which
satisfy various axioms. The set X together with this topology is
called a topological space. ## Related category• TOPOLOGY | |||||
