limit point of a set pdf If G is an open subset of mathbb R then every point of G is a limit point of G Solution In fact more is true If G is open and a in G then a is a limit point of G
Note 0 0 is a limit point of A Note that if x y 2A then x2 2y x y x y so that lim x y 0 0 x2 y2 x y lim x y 0 0 x y 0 So the limit does exist Norman likes the following result In this section we finally define a closed set We also introduce several traditional topological concepts such as limit points and closure Definition A subset A of a topological

Notation A set of limit points of A Example A Q R A R Since any interval contains some rational numbers A R Since any interval contains infinitely many rational numbers Set C in X d is closed if it contains all of its limit points Note that every point in C is a limit point of C take the constant sequence x x x the point of being closed is that the opposite
