Value distribution and uniqueness on $q$-differences of meromorphic functions
Zhi-Bo Huang
University of Eastern Finland
In this paper, by using the $q$-difference analogue of lemma on the logarithmic derivative lemma to re-establish some estimates of Nevanlinna characteristics of $f(q z)$, we deal with the value distribution and uniqueness of certain types of $q$-difference polynomials.
Keywords: uniqueness, $q$-difference polynomial, characteristic function, sharing value
