Abstract:

This paper first surveys geometric inequalities achieved mainly by the Chinese mathematicians. By estimating the containment measure of
a random convex body to be contained in, or to contain, another convex body via the fundamental kinematic formula of Blaschke and the formula of Poincarè in plane integral geometry, we obtain the classical isoperimetric inequality and some Bonnesen-style inequalities. Then some new geometric inequalities, such as the symmetric mixed isoperimetric inequality, Minkowski  and Bonnesen style symmetric mixed isohomothetic inequalities, are obtained. We also investigate the Gage type isoperimetric inequalities and the Ros type isoperimetric inequalities.

Key words: Convex set, The isoperimetric inequality, The Bonnesen-style inequality, The isohomothetic inequality, The Gage isoperimetric inequality, The Ros isoperimetric inequality
