The link to the paper by Rajendra Bhatia and Ludwig at springerlink.com is broken. Possibly it is meant to point to the following article: Bhatia, Rajendra; Elsner, Ludwig, The Hoffman–Wielandt inequality in infinite dimensions, Proc. Indian Acad. Sci., Math. Sci. 104, No. 3, 483–494 (1994). Zbl 0805.47017.
