Os sistemas completos de desigualdades propostos por Santaló

Abstract

In 1961, Santaló[21] suggested that, considering the family of the convex bodies in R2, it was found a complete system of inequalities for each pair and each triple of the functions area, perimeter, diameter, inradius, circunradius and minimal width. In this work, we applied the technique developed by Blaschke[2] to solve all problems suggested by Santaló, those are solved until now.
