Abstract
In this paper, we show that for any finite order entire function
$f(z)$, the function of the form $f(z)^{n}[f(z+c)-f(z)]^{s}$ has no
nonzero finite Picard exceptional value for all nonnegative integers
$n, s$ satisfying $ngeq 3$, which can be viewed as a different
result on Hayman conjecture. We also obtain some
uniqueness theorems for difference polynomials of entire functions
sharing one common value.
