On the problem of rationality for some cubic complexes
Let V be the complete intersection of smooth, generic quadric and cubic hypersurfaces in ℙ5(ℂ). V is a non rational Fano threefold. It is interesting to study the rationality of V when it contains n planes. This problem has been solved when the planes meet two by two in one point only. We consider and solve all remaining cases.
