Abstract:
We prove that every geometrically reduced projective variety of pure dimension over a field of positive characteristic admits a morphism to projective -space, étale away from the hyperplane at infinity, which maps a chosen divisor into and some chosen smooth points not on the divisor to points not in . This improves an earlier result of the author, which was restricted to infinite perfect fields. We also prove a related result that controls the behavior of divisors through the chosen point.
