Infinitely many positive solutions for Kirchhoff-type problems

Abstract This paper is concerned with the existence of infinitely many positive solutions to a class of Kirchhoff-type problem − ( a + b ∫ Ω | ∇ u | 2 d x ) Δ u = λ f ( x , u ) in Ω and u = 0 on ∂ Ω , where Ω is a smooth bounded domain of R N , a , b > 0 , λ > 0 and f : Ω × R → R is a Caratheodory function satisfying some further conditions. We obtain a sequence of a.e. positive weak solutions to the above problem tending to zero in L ∞ ( Ω ) with f being more general than that of [K. Perera, Z.
