Note on the inequality of the arithmetic and geometric means

Hao Zhi Chuan

Vol. 143 (1990), No. 1, 43–46
Abstract

We show how to insert a continuum of additional terms (defined by an integral and depending on an arbitrary positive parameter) between the two sides of the generalized arithmetic-geometric mean inequality with weights. Applications give an inequality involving positive definite matrices and also a refinement of the inequality connecting the inscribed and circumscribed radii of a triangle.
