Via critical point theory we establish the existence and regularity of solutions for the quasilinear elliptic problem
⎧ $div𝓐(x,∇u) + a(x)|u|^{p-2}u = g(x)|u|^{p-2}u + h(x)|u|^{s-1}u$ in $ℝ^{N}$
⎨
⎩ u > 0, $lim_{|x|→ ∞} u(x) = 0$,
where 1 < p < N; a(x) is assumed to satisfy a coercivity condition; h(x) and g(x) are not necessarily bounded but satisfy some integrability restrictions.
