초록

In this paper we prove the existence of nontrivial weak solutions to the boundary value problem -G1u = u3 + f(x, y, u) in Ω, u ≥ 0 in Ω, u = 0 on ∂Ω, where Ω is a bounded domain with smooth boundary in ℝ3, G1 is a Grushin type operator, and f(x, y, u) is a lower order perturbation of u3 with f(x, y, 0) = 0. The nonlinearity involved is of critical exponent, which differs from the existing results in [11, 12].
