f of the integer points. I found the problem at http://www.mathlinks.ro/viewtopic.php?t=150659 where one solution was given but I was wondering if there is some other way to find the integer points. However, I haven't found any proof which uses advanced methods. Jaakko -- To post to this

Hello again! Is that method general? I tried now to find the integer points of x^3 - 3*x*y^2-y^3-1 without success. Jaakko sage: R. = QQ[] sage: P = x^3 - 81/4 + y^2 sage: E=EllipticCurve(P) --- NotImplementedError

I read from http://mathoverflow.net/questions/7907/elliptic-curves-integer-points than Sage can determine the integer points of an elliptic curve. What commands will do the trick? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to

[sage-support] Root simplifying

Is there any function on Sage which can simplify the expression with sum of nth roots on denominator to the form that there are no roots on the denominator? Or even general, if the denominator contains various roots like 4th and 7th root on the same denominator. --~--~-~--~~---
