| Abstract: | In this paper, the three concepts of Lp-mixed centroid bodies Γp,iK and dual Lp-mixed centroid bodies Γ-p,iK and Lp-mixed harmonic Blaschke add  of star bodies  are introduced. The Shephard's question of Lp-mixed centroid bodies and dual Lp-mixed centroid bodies are solved succeed. In addition, the Brunn--Minkowski inequalities of the quermassintegrals and dual quermassintegrals of Lp-mixed centroid bodies associated with Lp-mixed harmonic Blaschke add are established, respectively. They extend some results of before document.
