Albo Carlos Cavalheiro · Applicationes Mathematicae · 2014
We investigate the existence and uniqueness of solutions to the Dirichlet problem for a degenerate nonlinear elliptic equation $$ - \sum _{i,j=1}^nD_j(a_{ij}(x)D_iu(x)) + b(x)u(x) + \mathop {\rm div} olimits (\varPhi (u(x))) = g(x) - \sum _{j=1}^n f_j
