In this work we study the behavior of the solutions to the following Dirichlet problem related to the anisotropic (p, q)-Laplacian operator [ left{egin{array}{ll} -mbox{div}_x(|
abla_x u|^{p-2}
abla_x u) -mbox{div}_y(|
abla_y u|^{q-2}
abla_y u)= 0 & mbox{in}, Omega,\[4pt] u=g & mbox{on}, partial Omega,\ end{array}
ight. ] as p, q → ∞. Here Ω ⊂ ℝN × ℝK and $
abla_xu = (frac{partial u}{partial x_1}, frac{partial u}{partial x_2}, dots, frac{partial u}{partial x_N})$ and $
abla_yu= (frac{partial u}{partial y_1}, frac{partial u}{partial y_2}, dots, frac{partial u}{partial y_K})$ denote the gradient of u with respect to the first N variables (x variables) and with respect to the last K variables (y variables). We consider a sequence of exponents (pn, qn) that goes to infinity with pn/qn → R. We prove that un, the solution with p = pn, q = qn, verifies un → u∞ uniformly in $overline{Omega}$, where u∞ is the unique viscosity solution to [ left{egin{array}{ll} - ...
