A Note on the Proof of the Perron-Frobenius Theorem

This paper provides a simple proof for the Perron-Frobenius theorem concerned with positive matrices using a homotopy technique. By analyzing the behaviour of the eigenvalues of a family of positive matrices, we observe that the conclusions of Perron-Frobenius theorem will hold if it holds for the starting matrix of this family. Based on our observations, we develop a simple numerical technique...

A different short proof of Brook's theorem

Lovász gave a short proof of Brooks’ theorem by coloring greedily in a good order. We give a different short proof by reducing to the cubic case.

A Short Proof of Zheludev's Theorem

We give a short proof of Zheludev's theorem that states the existence of precisely one eigenvalue in sufficiently distant spectral gaps of a Hill operator subject to certain short-range perturbations. As a by-product we simultaneously recover Rofe-Beketov's result about the finiteness of the number of eigenvalues in essential spectral gaps of the perturbed Hill operator. Our methods are operato...

A Short Proof of McDougall's Circle Theorem

This note offers a short, elementary proof of a result similar to Ptolemy’s theorem. Specifically, let di,j denote the distance between Pi and Pj . Let n be a positive integer and Pi, for 1 ≤ i ≤ 2n, be cyclically ordered points on a circle. If Ri := ∏ 1 ≤ j ≤ 2n j 6= i di,j , then n ∑
