Relative Perturbation Bound for Invariant Subspaces of Indefinite Hermitian Matrix
We give bound for the perturbations of invariant subspaces of nonsingular indefinite Hermitian matrix H under relative additive perturbations of H. Such perturbations include the case when the elements of H are known up to some relative tolerance.

Polynomial Numerical Hulls of Matrices
. For any n-by-n complex matrix A, we use the joint numerical range W(A,A 2,..., A k) to study the polynomial numerical hull of order k of A, denoted by V k (A). We give an analytic description of V 2 (A) when A is normal.

A Note On The Field Of Values Of Non-Normal Matrices
. It is shown that the distance from zero of the field of values of a matrix A depends on how large the departure from normality is compared to the distance from the zero of the field of values of the normal part of A.
