The inequalities of Petty and Zhang are affine isoperimetric-type providing sharp bounds for $\text{vol}^{n-1}_{n}(K)\text{vol}_n(\Pi^\circ K),$ where $\Pi K$ is a projection body convex $K$. In this paper, we present number generalizations Zhang's inequality to the setting arbitrary measures. addition, introduce extensions operator $\Pi$ measures functions, while associated operator; in partic...
