We prove the existence of solutions for an elliptic partial differential equation having more general flux term than either 𝑝 -Laplacian or flux term of the Leray-Lions type conditions: 𝑛 𝑗 = 1 ( 𝜕 / 𝜕 𝑥 𝑗 ) ( 𝛼 ( | 𝑢 𝑥 𝑗 | ) / 𝑢 𝑥 𝑗 ) = 𝑓 . Brouwer's fixed point theorem is one of the fundamental tools of the proof.
