Abstract:
This paper improves the previous results, the following theorem is established: Let
f(z) and
g(z) be two non-constant entire functions, and satisfy

, where
p1(z) and
p2(z) are two discriminant polynomials, if
p1(z) and
p2(z) are IM sharing functions of
f(z) and
g(z), and
f(z)-g(z) has infinitely zero of multiplicity, then
