Connected Topological Spaces
Please show why (briefly) each of the following top. spaces is or is not connected as indicated. Thank you.
a) Reals with the "usual topology." Why connected?
b) Reals with the "finite complement topology:" U open in X if U - X is finite or is all of X. Why connected?
c) Reals with the "countable complement topology:" U open in X if X - U is countable or is all of X. Why connected?
d) Reals with the "lower limit topology:" basis half-closed intervals [a,b). Why not connected?
e) Reals with the "upper limit topology:" basis half-closed intervals (a,b]. Why not connected?
f) Reals with the "K-topology:" basis consists of open intervals (a,b)and sets of form (a,b) - K where K = {1, 1/2, 1/3, ... } Why connected?
