Consider the set of all vectors \(\xi=(\xi_1,\xi_2,\xi_3)\) in \(\C^(3)\) for
which
- \(\xi_1\) is real
- \(\xi=0\)
- \(|\xi_1|> 0\)
- either \(\xi_1\) or \(\xi_2\) equal to zero
- \(\xi_1+\xi_2=0\)
- \(\xi_1+\xi_2=1\)
In which of the above cases do the set of all vectors form \(\xi\) form a vector
space?
