On the Perelman-Pukhov quotient of successive radii: better and asymptotically optimal bounds
Bernardo González Merino, Beatriz MarÃn Gimeno, Mia Runge
Perel'man in 1987 and independently Pukhov in 1979 proved that the quotient between the -th successive outer radius and the -th successive inner radius of a convex body…

Minimization of the inradius of convex bodies for prescribed diameter and circumradius in Minkowski spaces
René Brandenberg, Bernardo González Merino, Mia Runge
We study Blaschke-Santaló diagrams for the inradius, circumradius, and diameter in arbitrary-dimensional Minkowski spaces. Their boundary parts are regularly described by four lin…

A complete system of inequalities for the diameter, in-, and circumradius in the 3-dimensional Euclidean space
René Brandenberg, Bernardo González Merino, Mia Runge
We present a complete system of inequalities for the inradius, circumradius, and diameter in the -dimensional Euclidean space. To do so, we prove quasiconcavity of the inradius…
