Open sets and closed sets in topology
WebWe've defined the connectedness in topology in class in this way that a topological space is connected if the only both open and closed set is empty set or the whole set. Now I got the explanation from Wikipedia:"Now consider the space X which consists of the union of … WebSo while the words OPEN and CLOSED are suggestive of intervals, they are are just abstract labels where the OPEN sets satisfy the above for some property P. as far as the …
