Nov 22 comment How to numerically solve such differential system (ODE, Nonstationary, Nonhomogeneous) (what steps to take)? 1) What is $d$? 2) There is no bc on $v_2(0)= 0$ so how can we get a solution for $v_2(s)=eq$ and not $eq + const$ so there are more unknowns thn equations amnd we will not be capable to solve the system? 3) why we take only last 3 equations?

Does the fact of $v_4$ and $v_6$ make it not an ODE? Isnt it possible to get $v_4$ and $v_6$ out from given vs? make them depand on other vs? Nov 21 comment How to numerically solve such differential system (ODE, Nonstationary, Nonhomogeneous) (what steps to take)? boundary conditions are correct.

So... for me $S(1)$ not $= S(\alpha)$ not $= S(\alpha^2)$ not $=0$ 1) are you sure that $\dfrac{S(\alpha)}{S(1)}$ shall be $=$ to $\dfrac{S(\alpha^2)}{S(\alpha)}$ and $=$ to $\alpha^{i_0}$? I get $\alpha^5$ in $\dfrac{S(\alpha)}{S(1)}$ and $\alpha^5+\alpha^4+\alpha$ on $\dfrac{S(\alpha^2)}{S(\alpha)}$... 2) I cant get anething out from BruteForce *(all combinations of $S(\alpha^2) + [(1+\alpha)S(\alpha)]x + [\alpha S(1)]x^2$ are not NULL =( So what shall I do?
