Talk:Projective Hilbert space

From Wikipedia, the free encyclopedia

Well, isn't CP^1 a one-dimensional projective space...?

[edit] lambda

Because λ is complex, it is misleading to say that λ has to have absolute value of 1. Rather, the modulus has to be one, which implies λ = e^iθ,θ real. Thus we can alter the phase of the element of the Hilbert space. —Preceding unsigned comment added by Nardis miles (talk • contribs) 07:42, 29 October 2007 (UTC)
