Abstract
In the paper, we recall the Wallman compactification of a Tychonoff space (denoted by ) and the contribution made by Gillman and Jerison. Motivated by the Gelfand-Naimark theorem, we investigate the homeomorphism between and . Along the way, we attempt to justify the advantages of Wallman compactification over other manifestations of Stone-\v{C}ech compactification. The main result of the paper is a new form of Arzel\`a-Ascoli theorem, which introduces the concept of equicontinuity along -ultrafilters.
