摘要

We establish Liouville type results for weighted anisotropic elliptic equations in divergence form in the strip \({\mathbb {R}}^{N-1}\times (-1,1)\) R N - 1 × ( - 1 , 1 ) , \(N\ge 2\) N 2 . The weights depend on one variable and they include the case where they are powers of the distance functions to the boundary of the strip.
