We obtain the Morse critical groups at zero. The results show that the energy functional of the problem is trivial. As a consequence, the existence and bifurcation of the nontrivial solutions to the problem are established.eninfo:eu-repo/semantics/closedAccessP-LaplacianSign-Changing Weight FunctionMorse Critical GroupsArticle312247254WOS:0002746268000122-s2.0-7795065067210.1007/s10483-010-0212-6Q1Q3
