Query: Three solutions for a new Kirchhoff-type problem   This article concerns on the existence of multiple solutions for a new
Kirchhoff-type problem with negative modulus. We prove that there exist three
nontrivial solutions when the parameter is enough small via the variational
methods and algebraic analysis. Moreover, our fundamental technique is one of
the Mountain Pass Lemma, Ekeland variational principle, and Minimax principle.
