[sage-devel] Possible bug, weird base field change when working with polynomial rings

2019-06-14 Thread Henry Talbott
The following code produces the weird result: sage: R.=QQ[] sage: S.=R[] sage: u=FractionField(S)(x^2+y^2) sage: v = u.numerator()/u.denominator() sage: print u.numerator().parent() sage: print v.numerator().parent() Output: Multivariate Polynomial Ring in x, y over Univariate Polynomial Ring

[sage-devel] Why _r_action_ and _l_action_ methods still in the reference manual?

Hi I noticed that the coercion section of the sage reference manual mentions _r_action_ and _l_action methods instead of _act_on_ and _acted_upon_ methods, while it seems that the former methods were replaced with the latter methods 10 years ago in #5597! Am I right? Then this is quite
