abstract:
When the nonlinearities satisfy the growth conditions on a finite interval, some 
existence results of solutions to the boundary value problems of fractional 
differential equations are established via comparison theorem, upper and lower 
solutions method and fixed point theorems. An example is presented to illustrate 
the applications of the obtained results.
