Let A = [GRAPHICS] be the 2 X 2 diagonal operator matrix determined by a positive bounded linear operator A on a Hilbert space. For semi-Hilbertian op......

Let M be a semifinite von Neumann algebra. We proved that if [GRAPHICS] and [GRAPHICS] are positive matrices with entries in M, then z is logarithmica......
