a set is bounded above then supremum exist, bounded and unbounded sets, a non empty bounded subset has a supremum and infimum, bounded unbounded sets, bounded above set has a supremum, supremum exist for a bounded above set, bounded set, unbounded set definition, bounded sets, #bounded_set, upper bounds and lower bounds, unbounded sets, unbounded set example, least upper bound and greatest lower bound, closed sets, supremum of the union of sets
