  "abstract": "It is well known that non-negative solutions to the Dirichlet problem $\\Delta u =f$ in a bounded domain $\\Omega$, where $f\\in L^q(\\Omega)$, $q>\\frac{n}2$, satisfy $\\|u\\|_{L^\\infty(\\Omega)} \\leq C\\|f\\|_{L^q(\\Omega)}$. We generalize this result by replacing the Laplacian with a degenerate elliptic operator, and we show that we can take the data $f$ in an Orlicz space $L^A(\\Omega)$ that, in the classical case, lies strictly between $L^{\\frac{n}{2}}(\\Omega)$ and $L^q(\\Omega)$, $q>\\frac{n}2$.",
