Shi, Yongxiu; Wan, Haitao Pointwise boundary behavior of large solutions to \(\infty\)-Laplacian equations. (English) Zbl 1492.35050 Rocky Mt. J. Math. 52, No. 3, 1047-1061 (2022). Summary: We study the pointwise boundary behavior of the \(\infty\)-Laplacian problem \[\Delta_\infty u = b(x) f(u), \quad u \geq 0, x \in \Omega, u|_{\partial\Omega} = \infty,\] where \(b \in C(\bar{\Omega})\) is positive in \(\Omega\), \(f \in C[0, \infty) \cap C^1 (0, \infty)\) is positive and nondecreasing on \((0,\infty)\) and satisfies an Keller-Osserman type condition.
