Function

HenselLift ( elt-alg^pol F, elt-res^pad x ) -> elt-res^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);;x_Z5Q:= Quotient(x_Z5,5^3); x_Z5P:= PolynomialAlgebra(x_Z5Q);;x_f:= x_Z5P.1^2 +1;; x_x:= Element(x_Z5Q,2);; HenselLift(x_f,x_x);
