Hi, I have two questions regarding the implementation of multivariate power series is Sage.
I was wondering if Weierstrass Preparation Theorem and Hensel Lemma ( which use multivariate power series) have been implemented in Sage. About the implementation of multivariate power series (which use the lazy algorithm): suppose that we want to compute the inverse of a power series, from the documentation I know that Sage has a default precision for computation and in order to get more term we need to set the default_prec option of the power series ring to our desired value. I am wondering when we increase the accuracy does Sage remember the terms which have been computed so far?
