Systems with discrete singular $\varphi$-Laplacian and maximal monotone boundary conditions

Andreea Gruie, Petru Jebelean, Calin Serban

We are concerned with solvability of nonlinear systems involving a discrete singular $\varphi$-Laplacian operator of type \begin{equation*} u \mapsto Δ\left[ϕ(Δu(n-1))\right] \qquad (n\i…
