[sage-support] non parametric curve plot

2015-05-18 Thread Evrim Ulu
Hello, Is there a way to plot non-parametric curve of 2-variables f(x,y)=0? I've seen the documentation always employs rational parametrization or uses plot3d. best, evrim. -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe from

[sage-support] Casting a univariate poly to multivariate

2015-05-15 Thread Evrim Ulu
Hello, I am looking for a nicer way to cast a univariate poly to a multivariate ring with the different base fields. Basically base fields are both GF(2^3) but with different generators. I want generator of the first to be mapped to the generator of the second. sage: f x^6 + a*x^5 + (a + 1)*x^4

One more question If I may ask. Is there a way to get the minimal poly of some conjugates over GF(2^4)? I always end up degree 28 in this case, i want to see some of degree 7. I've tried to embed it into GF(2^4)[x] and factor yet no luck. Best, evrim. 2015-05-04 20:04 GMT+03:00 Evri

generating an Ideal. This is obviously untrue since k[x]() is a function who casts it into the ring. This is really confusing, Thanks for your help. best, evrim. 2015-05-04 18:27 GMT+03:00 Nils Bruin : > On Monday, May 4, 2015 at 7:58:19 AM UTC-7, Evrim Ulu wrote: >> >> I see t

Hello, I'm having trouble extending a finite field. Any help would be appreciated. F16 = GF(16, 'g') F16_x. = PolynomialRing(F16, 'x') HH = GF(F16^7, modulus=x^7 + x + 1, name='h') I basically try to extend 2^4 to 2^4*7 with a degree 7 irreducible. I get the following. best, evrim. sage: HH =
