Query: On rational fixed points of finite group actions on the affine space   Consider a finite l-group acting on the affine space of dimension n over a
field k, whose characteristic differs from l. We prove the existence of a fixed
point, rational over k, in the following cases:
  --- The field k is p-special for some prime p different from its
characteristic.
  --- The field k is perfect and fertile, and n = 3.
