A general framework of polar Brunn-Minkowski theory that unifies the Orlicz Brunn-Minkowski inequality,the Lp Brunn-Minkowski inequality for p ∈ (0,1) and the log-Brunn-Minkowski inequality all for polar bodies is provided.It is shown that this general polar φ Brunn-Minkowski inequality is equivalent to a general polar φ Minkowski mixed volume inequality.
