Perturbed nonlinear degenerate problems in
Via critical point theory we establish the existence and regularity of solutions for the quasilinear elliptic problem ⎧ in ⎨ ⎩ u > 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.
