One of the application areas of abstract convexity is inequality theory. In this work, the authors seek to derive new inequalities by sharpening well-known inequalities by the use of abstract convexity. Cauchy-Schwarz inequality, Minkowski inequality and well-known mean inequalities are studied in this sense, concrete results are obtained for some of them. Mathematics subject classification (20...

We present a Diaz–Metcalf type operator inequality as a reverse Cauchy–Schwarz inequality and then apply it to get some operator versions of Pólya–Szegö’s, Greub–Rheinboldt’s, Kantorovich’s, Shisha–Mond’s, Schweitzer’s, Cassels’ and Klamkin–McLenaghan’s inequalities via a unified approach. We also give some operator Grüss type inequalities and an operator Ozeki– Izumino–Mori–Seo type inequality...

Some new results that provide refinements and reverses of the Cauchy-Bunyakovsky-Schwarz (CBS)−inequality in the general setting of Measure Theory and under some boundedness conditions for the functions involved are given.

In this paper, some reverses of the Cauchy-Bunyakovsky-Schwarz inequality in 2-inner product spaces are given. Using this framework, some applications for determinantal integral inequalities are also provided.

The squeezing and violation of the Cauchy-Schwarz inequality in the fluorescent field of collective double resonant process are discussed. J. Physique 48 (1987) 1925-1931 NOVEMBRE 1987, Classification Physics Abstracts 42.50
