Abstract
Let be a field.We describe necessary and sufficient conditions for a -linear abelian category to be a noncommutative projective line, i.e. a noncommutative -bundle over a pair of division rings over . As an application, we prove that , Piontkovski’s th noncommutative projective line, is the noncommutative projectivization of an -dimensional vector space.
