Re: [sage-support] Re: Calling Sage on Windows from external scripts

Thanks David. It sounds like that will require some changes in PreTeXt itself. I was experimenting because I got a new Windows computer at work, to know how well PreTeXt is currently supported on Windows. I think the answer might be that everything works locally, as long as your book doesn't

If you have Python script running locally on Windows, you could call the sage script by doing something like: import os os.system('wsl sage your-sage-script.sage') See this page: https://learn.microsoft.com/en-us/windows/wsl/filesystems for more about Windows-Linux interoperability.

Answering part of my question: it seems that sympy and maxima have different attitudes towards fractional powers of negative numbers, which may be the source of the problem. Yes. Maxima's attitude is that the square root of negative one is an expression which might have multiple values,

Answering part of my question: it seems that sympy and maxima have different attitudes towards fractional powers of negative numbers, which may be the source of the problem. If I change to g(x,y)=x^2+6*y then "solve" has no problem finding x=2*sqrt(6), y=16. Fernando On 11/28/2023 10:36

Thanks for this report, which certainly indicates a bug. I will look into it as the code here was written by me. I note that the two curves have CM (by the order of index 5 and the maximal order in Q(sqrt(-3)) respectively), and the code to deal with isogenies is different in this case. The

Re: [sage-support] Re: Canonical divisor help

The most pressing problem in sage at the moment seems to be that presently there only seem to be morphisms between schemes. You need rational maps for this (especially from a singular model, the map to a canonical model might only be a rational map). "SchemeMorphism" in Sage is a map
