Abstract
In this paper we investigate the optimal problem for the mixed chord integral. The existence of the chord integral–Petty bodies is established, and the geominimal chord integral is proposed and its properties, such as invariance under orthogonal matrices, homogeneity, isoperimetric-type inequalities and cyclic-type inequalities, which are provided as well.
