Maximal Flow Through a Network,The problem discussed in this paper was formulated by T. Harris as follows:.“Consider a rail network connecting two cities by way of a number of intermediate cities, where each link of the network has a number assigned to it representing its capacity. Assuming a steady state condition, find a maximal flow from one given city to the other.”

Their proof of the generalization appears to duplicate the usual proof of Tychonoff’s theorem.. The purpose of this note is to simplify the presentation by employing the statement rather than the proof of that result. At the same ti
