In this paper, two problems related to the following class ofelliptic Kirchhoff-Boussinesq-type models are analyzed in the subcritical(beta= 0) and critical (beta= 1) cases: Delta(2)u-Delta(p)u=tau|u|(q-2)uln|u|+beta|u|(2)& lowast;& lowast;(-2)u in Omega and Delta u=u=0 on partial derivative Omega, where tau > 0, 2 < p < 2 & lowast; = 2N/N-2 for N >= 3 and 2(& lowast;& lowast; )= infinity for N = 3, N = 4, 2(& lowast;& lowast; )= 2N/N-4 for N >= 5. The first one is concerned with the existence of a nontrivial ground-state solution via variational methods. As for the second problem, we prove the multiplicity of such a solution using the Mountain Pass Theorem.
