1.7.3.2 How to solve a system with infinitely many equations?

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=245194

I need to solve the following system of (infinitely many) equations. I am looking for \(V(0,0)\)

\(t \in \{0,1,2.....\}\) with one caveat that \(s \leq 1+t\) should hold.

\( s \in \{1,2,3,L-1\}\)

fixed ...
