Value distribution of q-difference differential polynomials of entire functions

For a complex value q � 0, 1, and a transcendental entire function f (z )w ith order, 0< σ (f )< ∞, we study the value distribution of q-difference differential polynomials [f n (z)(f (qz )– f (z))] (k) and [f (z)f (qz)] (k) . MSC: 30D35; 39A05
