On existence and uniqueness of positive solutions to a class of fractional boundary value problems

摘要

The purpose of this paper is to investigate the existence and uniqueness of positive solutions for the following fractional boundary value problem D 0 + α u ( t ) + f ( t , u ( t ) ) = 0 , 0 t 1 , u ( 0 ) = u ( 1 ) = u ′ ( 0 ) = 0 ,
