摘要：

By means of a new Cauchy-Schwarz inequality in the framework of a semi-inner product C* -module over a unital C* -algebra, we discuss some operator inequalities on a Hilbert C* -module, for example, Kantorovich inequaity, Polya-Szego inequality, the covariance-variance inequality, Ozeki-Izumino-Mori-Seo inequality, Wielandt inequality, Hienz-Kato-Furuta inequality and Malamud inequality.
