LIMITED APPROXIMATION OF NUMERICAL RANGE OF NORMAL MATRIX
(2010)Let A be an n x n normal matrix, whose numerical range NR[A] is a k-polygon. If a unit vector v is an element of W subset of C(n), with dimW = k and the point v*Av is an element of IntNR[A], then NR[A] is circumscribed to ... -
On numerical ranges of the compressions of normal matrices
(2011)For an n x n normal matrix A, whose numerical range NR[A] is a k-polygon (k <= n), an n x (k - 1) isometry matrix P is constructed by a unit vector upsilon is an element of C(n), and NR[P*AP] is inscribed to NR[A]. In this ...
