“…Recently, the anisotropic elliptic or parabolic equations attract much attention, in other words, people turn to study of the anisotropic p ‐Laplacian equations, where the anisotropic operator is where is a constant vector, , we refer to [2, 6, 9–13, 15, 16, 23, 25, 26, 29, 35] and their references. In especially, we would like to mention the result of Agnese DI Castro, Eugenio Montefusco [12] who considered the following anisotropic quasilinear degenerate elliptic equations where Ω is a bounded subset of , and assume are ordered.…”
