Abstract: We consider the following (p,q)-Laplacian Kirchhoff type problem
−(a+b∫R3|∇u|pdx)Δpu−(c+d∫R3|∇u|qdx)Δqu+V(x)(|u|p−2u+|u|q−2u)=K(x)f(u)in R3,
where a,b,c,d>0 are constants, 32<p<q<3, V:R3→R and K:R3→R are positive continuous functions allowed for vanishing behavior at infinity, and f is a continuous function with quasicritical growth. Using a minimization argument and a quantitative deformation lemma we establish the existence of nodal solutions.
