A. McD. Mercer and Peter R. Mercer

International Journal of Mathematics and Mathematical Sciences, 2000, vol. 23, 1-4

Abstract:

We present a short and simple proof of the well-known Cauchy interlace theorem. We use the theorem to improve some lower bound estimates for the spectral radius of a real symmetric matrix.
