# Abstract

In this article, we study the following fractional boundary value problem $D 0 + α c u ( t ) + 2 r D 0 + α − 1 c u ( t ) + r 2 D 0 + α − 2 c u ( t ) = f ( t , u ( t ) ) , r > 0 , 0 < t < 1 ,$ $u ( 0 ) = u ( 1 ) , u ′ ( 0 ) = u ′ ( 1 ) , u ′ ( ξ ) + r u ( ξ ) = η , ξ ∈ ( 0 , 1 )$ Where $2 ≤ α < 3 , D 0 + α − i c ( i = 0 , 1 , 2 )$ are the standard Caputo derivative and $η$ is a positive real number. Some new existence results are obtained by means of the contraction mapping principle and Schauder fixed point theorem. Some illustrative examples are also presented. View Full-Text
