Definition of Neighbourhood of a point Definition of Open set infinite intersection of open sets need not to be open Union of two NBDS is NBD Intersection of NBDS is NBD Superset of a NBD is also a NBD Every Open interval (a,b) is neighbourhood of each of its points. Closed interval is neighbourhood of each point except end points. real numbers is NBD of each real number Rational numbers set is not the neighbourhood of any of its points.
