1) Show that one point compactification of N(set of natural numbers) is homeomorphic wit {1/n : n in N} union {0}. 2)Show that one point compactification of R(set of real numbers) is homeomoerphic with S1(unit circle).. any help is appreciated..

Denote the one-point compactification of by and and do what's natural. Define by . That would be my initial guess, but until you tell us what topology is put on these two sets there can be no discussion of continuity. The second one is done similarly.
