Abstract
The topology of the n-dimensional cube is used to reduce the problem of determining the minimal forms of a Boolean function of n variables to that of finding the minimal coverings of the essential vertices of the basic cell system associated with the given function. The proof of this statement is contained in the central Theorem 4. A numerical easily programmed procedure is given with which it is possible to treat problems with a greater number of variables than has heretofore been practical. The procedure by-passes the determination of the basic cells (the prime implicants of W. V. Quine) and locates the essential vertices, from which in turn the irredundant and minimal forms are obtained.

Application of Boolean algebra to switching circuit design and to error detection

TL;DR: It is shown that certain parts of the multiple output problem for switching circuits that have more than one output may be reduced to a single output problem whose inputs are equal in number to the sum of the numbers of inputs and outputs in the original problem.

Switching functions on an n-dimensional cube

TL;DR: This paper considers 2-terminal combinational networks from a somewhat different viewpoint, mainly a switching function will be considered as a set of Vertexes on an n-dimensional cube (n-cube).
