| Abstract: | The existence principle of single and multiple positive solutions for the first order discrete periodic boundary value problems was studied by employing a fixed point theorem in cones.Based on this principle,the existence of single and multiple positive solutions for the problems was given.Some new results about nonlinear difference equations on a finite discrete segment with periodic boundary conditions were demonstrated. |
