“…Moreover, problem (1.1) is related to the stationary version of the Kirchhoff equation which is presented by Kirchhoff in 1883, see [16] for details. One of the important hypotheses in these papers is that the Kirchhoff function M is non-degenerate, i.e., M.t / m 0 > 0 for all t 2 R C 0 WD OE0; C1/: Motivated by the ideas introduced in [8,10,12,22,23], the goal of this paper is to study the multiplicity of solutions for problem (1.1) in the case when the Kirchhoff function M.t/ may be degenerate at zero.
