It is proved that if K is an origin-symmetric convex body in R2 and Π*K is the polar projection body of K, then the volumes of K and Π*K satisfy the inequality V(K)V(Π*K) ⩾ 2 with equality if K is a parallelogram.
Key words:convex body; polar body; projection body; the reverse Petty projection inequality
CLC number:O 178; O 18
