[sage-devel] Suggested contribution: algebraic dependendecy of numerical data
Hi sage devs,
I am proposing contribution to sage.
Attaching https://j.ludost.net/code/algdep_numeric.py.txt
>From the comments:
Given a list F of numeric lists F_{i,1},F_{i,2},...F_{i,k}
Finds a list of polynomials G_i, such that G_i(F_j)=0
Examples:
F=[ [ZZ(fibonacci(2*i)),fibonacci(2*i+1)] for i in range(2,50)]
ag=algdepanalytic(F,D=2,check=1);ag
[x0^2 + x0*x1 - x1^2 + 1]
The X coordinate of an Elliptic Curve over finite field:
F=[ X(n*P),X((n+1)*P)]
p=next_prime(10**3);K=GF(p)
E=EllipticCurve(GF(p),[0,2]);P=E.gens()[0]
def X_n(P,n): return (n*P).xy()[0]
F=[ [X_n(P,2*i),X_n(P,2*i+1)] for i in range(2,47)]
ag=algdepanalytic(F,D=4,check=1);ag
[126*x0^2*x1^2 - 97*x0^2*x1 - 97*x0*x1^2 + 353*x0^2 + 303*x0*x1 +
353*x1^2 + x0 + x1 - 388]

[sage-devel] Re: Sage GSoC2023 Ideas Page
Hi everyone, I know things are a bit hectic with the transition right now. However, the deadline for submitting our GSoC proposal is tomorrow (at least for me). I would appreciate it if you could add a project (you don't have to agree to be a mentor) or let me know if you are willing to mentor a project (you do not need to have a specific project in mind/written). The GSoC rules this year seem to indicate that the duration of the project is somewhat variable, and as such, can be more focused on implementing more targeted features. Let me know if you have any questions.
