| Abstract: | In this paper,the existence of zeros and fixed points of difference of transcendental entire functions is in-vestigated. Under some conditions,Δ2 f( z)has infinitely many zeros and infinitely many fixed points,and Δ2 f( z)/f( z)has infinitely many zeros. |

| Keywords: | difference zero fixed point |
