摘要
We prove a weak comparison principle in narrow unbounded domains for solutions to in the case and is a power-type nonlinearity, or in the case and is super-linear. We exploit it to prove the monotonicity of positive solutions to in half spaces (with zero Dirichlet assumption) and therefore to prove some Liouville-type theorems.
