Abstract:
      In our work, our objective is to prove the existence and uniqueness of a weak solution to a class of nonlinear degenerate elliptic $(p,q)$-Laplacian problem with Dirichlet-type boundary condition by giving $L^{\infty}$ data. The principal technique utilized here is the variational method alongside the theory of Orlicz spaces and Minty-Browder theorem.
