Projective extensions of fields
Every field K admits proper projective extensions, that is, Galois extensions where the Galois group is a non-trivial projective group, unless K is separably closed or K is a Pythagorean formally real field without cyclic extensions of odd degree. As a consequence, it turns out that almost all absol...
