Investigates uniqueness in sharing functions between difference operators of entire functions, suggesting broader applications in mathematics.
In this paper, we consider the uniqueness problem of sharing a small function between n-th order difference operator Δcⁿf(z) and first-order difference operator Δcf(z) of a finite order transcendental entire function $$f(z)$$ . This mainly generalizes the corresponding result due to He et al. [15].
