CPⁿ, or, entanglement illustrated

الأصل · EN

We show that many topological and geometrical properties of complex projective space can be understood just by looking at a suitably constructed picture. The idea is to view CPⁿ as a set of flat tori parametrized by the positive octant of a round sphere. We pay particular attention to submanifolds of constant entanglement in CP³ and give a few new results concerning them.
