Systems with discrete singular -Laplacian and maximal monotone boundary conditions
Andreea Gruie, Petru Jebelean, Calin Serban
We are concerned with solvability of nonlinear systems involving a discrete singular -Laplacian operator of type \begin{equation*} u \mapsto Δ\left[ϕ(Δu(n-1))\right] \qquad (n\i…

Non-potential systems with relativistic operators and maximal monotone boundary conditions
Petru Jebelean, Calin Serban
We are concerned with solvability of a non-potential system involving two relativistic operators, subject to boundary conditions expressed in terms of maximal monotone operators. T…
