| ### Function GaloisImage ( elt-res^pad x, elt-ord^rat i ) -> elt-res^pad ### Description The image of x under the Frobenius automorphism composed with itself i times, that is, a -> a^(p^i) where a is the inertial element of the parent of x. ### Examples x_z5 := pAdicRing(5,30);x_r := UnramifiedExtension(x_z5,3); x_r5 := Quotient(x_r, 5^10); GaloisImage(x_r5.1,4);
