Web5 mei 2013 · Summary. In this chapter, we present two modular algorithms for factoring in Q [ x] and F [ x, y] for a field F. The first one uses factorization modulo a “big” prime and is conceptually easier, and the second one uses factorization modulo a “small” prime and then “lifts” it to a factorization modulo a power of that prime.

"WebHensel Lifting. Using the lemma, one can "lift" a root r of the polynomial f mod pk to a new root s mod pk +1 (by taking m =1; taking larger m also works). The new root s is congruent to r mod p, so the new root also satisfies . So the lifting can be repeated, and starting from a solution rk of we can derive a sequence of solutions rk+1, rk+2 ...
