as a matter of fact, we might currently be lacking developers with knowledge of these MacOS-specific things. (I suggest that SageMath-*.app should not be used, instead use terminal-based ways to start Sage) On Fri, Mar 20, 2020 at 2:35 AM rana-aere wrote: > > I think SageMath-9.0.app has less

mpfr needs makeinfo program to be installed. This is a pretty standard thing, which on Centos is in texinfo package https://centos.pkgs.org/7/centos-x86_64/texinfo-5.1-5.el7.x86_64.rpm.html By the way, why are you building Sage 8.9, and not 9.0? On Thu, Mar 19, 2020 at 7:00 AM Kashif Bari

[sage-support] defining (partial) inverse image of a ring homomorphism

Suppose I have R.=QQ[] K.=QQ[] f=R.hom([u*v,u^2,v^2-u^2]) then for any even degree p in K one can compute a preimage under f (e.g. u^4-u*v goes to y^2+x, etc) Does Sage support this kind of maps? Yes, I can write the code that will for an even degree monomial in K compute the corresponding

In fact, substituting x and y directly into the equation of the curve to plot, and clearing denominators, produces something pretty good,IMHO: implicit_plot(v^2*3*sqrt(1-u^2-v^2)-u^3*9+u*(1-u^2-v^2),(u,-1,1),(v,-1,1)) On Thu, Mar 5, 2020 at 4:51 PM Dima Pasechnik wrote: > > On Thu, Mar 5
