Abstract
An attainable upper matrix bound is derived for [GRAPHICS] improving u pon earlier bounds by Anderson and Taylor [Linear Algebra Appl. 30:93- 99 (1980)] and Olkin [Linear Algebra Appl. 52/53:529-532 (1983)]. Ineq ualities for the sum of harmonic means or parallel sums are derived as special cases. The more general problem of obtaining an upper bound f or [GRAPHICS] is also considered.
