Applications of elementary submodels in general topology
One may say that this paper is another introduction to applications of elementary submodels to topology. It is clearly intended to, and succeeds at, providing the basics for a reader interested in understanding proofs using elementary submodels. A nice proof is included that network-weight is equal to weight for compact spaces. A more advanced topic, briefly discussed, is that of internally approachable models and \(V_\kappa\)-like models. The final section reminds the reader of Bandlow's approach of using elementary submodels to define an equivalence relation, thereby a quotient space, of a compact space.
