[sage-support] bug in hyperelliptic curve point counting

2016-10-09 Thread John Cremona
I have not before now used Sage to count points on hyperelliptic curves over finite fields, only elliptic curves. Am I doing something wrong or is this a bug? It certainly looks like a bug. sage: F=GF(23) sage: x=polygen(F) sage: C=HyperellipticCurve(x^8+1) sage: C.cardinality() ... ValueError:

There is no advanced algorithm to do that in giac, but for simple examples like that it works: assume(a>1); assume(b>a); 2b>a; Le dimanche 9 octobre 2016 08:35:19 UTC+2, Ralf Stephan a écrit : > > > Maxima 5.37.2: > > (%i1) assume(a>1); > (%o1) [a > 1] > (%i2) assume
