[sage-support] Type set of symbols missing

hello, I've seen a topic on this issue regarding integrals, with a ticket that apparently is closed in the meantime. I do see the problem still appearing in 4.1 for - in this case - the sqrt symbol. Tried Mac OSX and on-line Sage. Simple examples: When I type a simple sqrt(2) I do get it

[sage-support] Division by zero in calculation of Weil Pairing

2009-08-06 Thread VictorMiller
In calculating the Weil Pairing of two points I get a pari division by zero error. Needless to say this shouldn't happen. I think that the solution is that if either of the miller_functions that are calculated yield a 0 then the value of the Weil Pairing must be 1. Here's some code that

Slight change. The code I gave works, but the following fails. I really don't know what there is about a non-prime finite field that causes this. Victor p=100019 E = EllipticCurve(j=GF(p^2,'r')(1728)) M = (p+1)//3 # find an element of order 3 while True: P = M*E.random_element() if P !=

2009-08-06 Thread VictorMiller
Hmm, In looking at ell_point.py at line 1181 it looks like it does the right thing. Somehow the pari error of division by 0 (perhaps in non- prime finite fields?) doesn't get raised as a ZeroDivisionError. This is a problem with the interface with pari: p = 100019 K.a = GF(p) L.b = GF(p^2)
