Asymptotic behavior of large solutions to \(p\)-Laplacian of Bieberbach-Rademacher type. (English) Zbl 1176.35080

Summary: By the Karamata regular variation theory and the method of lower and upper solutions, we establish the asymptotic behavior of boundary blow-up solutions of the quasilinear elliptic equation \(\text{div}(|\nabla_u|^{p-2}\nabla u)=b(x)f(u)\) in a bounded \(\Omega \subset\mathbb R^N\) subject to the singular boundary condition \(u(x)=\infty \), where the weight \(b(x)\) is non-negative and non-trivial in \(\Omega \), which may be vanishing on the boundary or unbounded, the nonlinear term \(f\) is a \(\Gamma \)-varying function at infinity, whose variation at infinity is not regular.
