摘要
In this paper, we investigate shared value problems related to an entire function f(z) of hyper-order less than one and its linear difference polynomial L(f) = Sigma(k)(i=1) a(i) f(z + c(i)), where a(i), c(i) is an element of C. We give sufficient conditions in terms of weighted value sharing and truncated deficiencies, which imply that L(f) equivalent to f.
