This paper is concerned with the existence of three solutions to a nonlinear fractional boundary value problem as follows: (𝑑/𝑑𝑑)((1/2)0π·π‘‘π›Όβˆ’1(𝐢0𝐷𝛼𝑑𝑒(𝑑))βˆ’(1/2)π‘‘π·π‘‡π›Όβˆ’1(𝐢𝑑𝐷𝛼𝑇𝑒(𝑑)))+πœ†π‘Ž(𝑑)𝑓(𝑒(𝑑))=0,a.e.π‘‘βˆˆ[0,𝑇],𝑒(0)=𝑒(𝑇)=0, where π›Όβˆˆ(1/2,1], and πœ† is a positive real parameter. The approach is based on a critical-points theorem established by G. Bonanno.
