    "abstract": "A generalized skew information is defined and a generalized uncertainty\nrelation is established with the help of a trace inequality which was recently\nproven by J.I.Fujii. In addition, we prove the trace inequality conjectured by\nS.Luo and Z.Zhang. Finally we point out that Theorem 1 in {\\it S.Luo and\nQ.Zhang, IEEE Trans.IT, Vol.50, pp.1778-1782 (2004)} is incorrect in general,\nby giving a simple counter-example.",
