2021-02-15 22:18:34 +0200 | commented question | Height of rational points My code for enumeration of points using elimination is here if anyone is interested. There is a hacked-up global height function for homogeneous coordinates. |
2021-02-15 12:58:12 +0200 | commented answer | Height of rational points That would be great, thanks a lot! BTW the algorithm for the enumeration of points on projective varieties is not very efficient. I wrote a package in Macaulay2 using elimination, maybe I'll try to port it to Sage too. |

2021-02-14 01:04:07 +0200 | asked a question | Height of rational points Hi, I'm looking at this example of enumeration of rational points from the documentation Enumeration of rational points on projective schemes. Here I'm considering the entire projective plane. The returned result includes several points like Edit. I reviewed the code, it seems that the problem is in the file |
