Concerning Connected and Regular Point Sets

In this paper an extension will be given of a theorem of the author'sf which states that if A and B are any two points of a continuous curve M, and K denotes the set of all those points of M which separate} A and B in M, then K+A+B is a closed set of points. I t will be shown that if A and B are any two points of any connected and regular (connected im kleinen) point set M, and K denotes the se...

A Note concerning Completely Regular Gyspaces1

Two results concerning distance-regular directed graphs

The study of distance-regular directed graphs can be reduced to that of short distance-regular directed graphs. We consider the eigenspaces of the intersection matrix of a short distance-regular directed graph and show that nearly all the eigenvalues are nonreal. Next we show that a nontrivial short distance-regular directed graph is primitive.

Separation Theorems with Applications to Questions concerning Accessibility and Plane Continua*

In this paper we shall confine ourselves to a two-dimensional euclidean space which we shall denote by the symbol S. R. L. Mooref has given the following extension of a theorem by Zoretti:} If K is a bounded maximal connected subset of a closed point set M and does not separate space, and e is a positive number, then there exists a simple closed curve containing no point of M, such that the int...
