Weighted shift matrices and refinements of generalized triangle inequalities.
博士 === 國立中央大學 === 數學研究所 === 100 === Assume that all aj''s are nonzero and B is a n-by-n weighted shift matrix with weights bj ''s. We show that B is unitarily equivalent to A if and only if a1 ￠ ￠ ￠ an = b1 ￠ ￠ ￠ bn and, for some ¯xed k, 1 · k · n, jbj j = jak+j j...
