Title: Location of Ritz values in the numerical range of normal matrices
Abstract: Let μ1 be a complex number in the numerical range W(A) of a normal matrix A. In the case when no eigenvalues of A lie in the interior of W(A), we identify the smallest convex region containing all possible complex numbers μ2 for which μ1∗0μ2 is a 2-by-2 compression of A.
