Real point

Real point

A point "(a,b,c)" in the complex projective plane is called real if there exists a complex number z such that "za, zb" and "zc" are all real numbers.

This definition can be widened to complex projective space and complex projective hyperspaces as follows:

: (a_1,a_2,...,a_n)

is real if there exists a complex number z such that

: (za_1, za_2,..., za_n)

is real.

(Note (0,0,...,0) is not a point)
