Elliptic problems involving a diffusion operator of vectorial $p\&q$-Laplacian type

M. L. M. Carvalho, J. R. Santos, H. W. G. Silva

We study a broad class of anisotropic Dirichlet problems driven by the nonhomogeneous operator \[ \mathcal L_Au=-\sum_{i=1}^N\partial_i\!\left( a_i(|\partial_i u|^{p_i})|\partial_i…
