Abstract
A number of results for Ritz values are presented. These are used to study the local effects in the convergence behavior of Ritz values corresponding to a pair of close eigenvalues in the spectrum. The local effects that are typical for such a situation are illustrated by numerical examples.

Theoretical error bounds are established, improving those given by S. Kaniel, and similar inequalities are found for the eigenvectors by using bounds on the acute angle between the exact eigenvesctors.

A simple algorithm which computes the largest eigenvalue is developed which is especially economical if the order of the matrix is large and the accuracy requirements are low.
