define limit point of a set A point a is said to be a limit point of a set S if there are points in S other than a that are arbitrarily close to a but never become equal to a For example 1 is a limit point of the intervals 0 1 and 0 2 because 0 9 0 99 0 999 0 999 dots is a sequence of points in those intervals that approaches 1 but never
Limit Point of a Set Let X X be a topological space with topology and A A be a subset of X X A point x X x X is said to be the limit point or accumulation point or cluster point of A A if each open set containing x x contains at Limit point of a set A point each neighbourhood of which contains at least one point of the given set different from it The point and set considered are regarded as belonging to a topological space A set containing all its limit points is called closed

Limit Points Suppose that A is a subset of a topological space X then a point x X is called a limit point of A when every neighborhood of x intersects A in some point other than x itself Limit Point iff element of Closure minus a Point x x A x Limit Points are a Subset of Closure The topological definition of limit point P of A is that P is a point such that every open set around it contains at least one point of A different from P A number x such that for all epsilon 0 there exists a member of the set y
