For polytopes P,Q ⊂ Rd we consider the intersection P ∪ Q; the convex hull of the union CH(P ∪ Q); and the Minkowski sum P+Q. We prove that given rational H-polytopes P1,P2,Q it is impossible to verify in polynomial time whether Q=P1+P2, unless P=NP. In particular, this shows that there is no output sensitive polynomial algorithm to compute the facets of the Minkowski sum of two arbitrary H-polytopes even if we consider only rational polytopes. Since the convex hull of the union and the intersection of two polytopes relate naturally to the Minkowski sum via the Cayley trick and polarity, similar hardness results follow for these operations as well.
