“…Some worthwhile studies of Kirchhoff equations include those by Graef et al [
15], Hssini [16], Matallah et al [
17], and references therein. It should be mentioned that the existence of solutions to the Kirchhoff‐type fractional differential equations addressed by variational methods has also received much attention from scholars [
18‐23], as models based on fractional order are better suited to describing the memory and hereditary properties of many processes and materials. Here, by using the mountain pass theorem and genus properties in the critical point theory, Chen et al [
20] were concerned with the following Kirchhoff‐type fractional Dirichlet problem with
‐Laplacian:
