Title: Horrors in topology, when N is not Lindelof!

Abstract: We will discuss a bit of the horrors of topology when the axiom of choice is on vacation.

We will see that it is enough to require that either N or R with their standard topologies are Lindelof in order to prove that every second countable space is separable and Lindelof.

Best,

Arkady Leiderman
