System of equations ::
1. v1^2*u1 + 2*v1*v0 + f3*u0 - f3*u1^2 + f2*u1 - f1 - u0^2 +
3*u0*u1^2 - u1^4 = 0
2. - v1^2*u0 + v0^2 - f3*u0*u1 + f2*u0 - f0 + 2*u0^2*u1 -
u0*u1^3 = 0
3. 2*u1*k1^2 = -1 + 2*k0*k1 + u1*k1^2
4. (2*u0 + u1^2)*k1^2 = k0^2 + u0*k1^2 + u1 + 2*k0*u1*k1 + 2*v1*k1
5. 2*u0*u1*k1^2 = -f3 + u0 + 2*k0*u0*k1 + k0^2*u1 - u1^2 + 2*v0*k1 + 2*k0*v1
6. u0^2*k1^2 = -f2 + k0^2*u0 + f3*u1 - 2*u0*u1 + u1^3 + 2*k0*v0 + v1^2
where variables are v1,v0,u0,u1,k0,k1 and f3,f2,f1,f0 are constants...
