I try to define a map between variables over a polynomial ring like x^2=y^3+y to a polynomial like x^2*y

I have try this F=PolynomialRing(GF(2^6),'x,y') x,y=F.gens() Func=x^2*y Func(x=(y^3+y)^(1/3))

But it doesn't work

Hope to get your help, thank you!

I try to define am working on a map between variables over a polynomial ring elliptic curve like x^2=y^3+y to a polynomial like x^2*yy^2+y=x^3

I have try this and i want to define a polynomial F=PolynomialRing(GF(2^6),'x,y')A(x,y) that x,y=F.gens()x,y satisfying Func=x^2*y Func(x=(y^3+y)^(1/3)) y^2+y=x^3

But it doesn't work
