In this paper, we study a class of Kirchhoff equation with steep potential well and concave–convex nonlinearities as follows: where , , , and is a steep potential well. Such problem has been rarely studied for the case since the appearance of the term . By combining the Ekeland variational principle and the filtration of Nehari manifold, we prove the multiplicity of positive solutions for the above problem when is sufficiently small and is large enough. Recent results from the literature are extensively improved and extended.

在本文中,我们研究了一类具有陡峭势阱和凹凸非线性的Kirchhoff方程,如下所示: 在哪里 , , , 和 潜力巨大。这种情况很少针对这种情况进行研究 自该词出现以来 。通过结合Ekeland变分原理和Nehari流形的过滤,我们证明了上述问题时正解的多重性。 足够小 足够大。文献的最新结果得到了广泛的改进和扩展。
