Abstract
In the paper, our main aim is to introduce a new concept and call it the \(L_p\)- mixed geominimal surface area \(G_{p}(K_{1},\,\dots\,,K_{n})\) of \(n\) convex bodies \(K_{1},\,\dots\,,K_{n}\), which obeys the classical basic properties. The new affine geometric quantity in a special case yields Petty’s geominimal surface area \(G(K)\) of a convex body \(K\), Lutwak’s \(p\)-geominimal surface area \(G_{p}(K)\) of \(K\), and the newly established mixed geominimal surface area \(G(K_{1},\,\dots\,,K_{n})\) of \(n\) convex bodies \(K_{1},\,\dots\,,K_{n}\). We establish some \(L_{p}\)-mixed geominimal surface area inequalities for the \(L_p\)-mixed geominimal surface area, whose some special cases are Petty’s geominimal surface area inequality, Lutwak’s \(p\)-geominimal surface area inequality, and some new mixed geominimal surface area inequalities.
