Function

HenselLift ( elt-alg^pol F, elt-ord^pad x ) -> elt-ord^pad

Description

Hensel lift x, an approximate root of F which satisfies the Hensel condition, to a root of F known to the full precision of the parent of x..

Examples

x_z5 := pAdicRing(5,20);;x_z5P:= PolynomialAlgebra(x_z5);; x_f:= x_z5P.1^2 +1;; x_x:= Element(x_z5,2);;HenselLift(x_f,x_x);
