Weighted value sharing and uniqueness of meromorphic functions

Uniqueness of meromorphic functions sharing two values

“…For more results in such directions, we refer the readers to [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. We recall the following result by Xu et al [25] or Zhang and Li [26], respectively.…”

“…Thus a and b are both polynomials and a(z) + b(z) ≡ C for a constant C. Hence, from (3.11) we get 14) whereP 2k−1 is a differential polynomial in a' of degree at most 2k -1. From (3.14)…”

On unicity of meromorphic function and its kth order derivative

“…In 2006, Lin and Lin [10] introduced the following notion of weakly weighted sharing which is the generalization of the idea of weighted sharing introduced in [8]. …”

Weighted sharing and uniqueness of memorphic functions with regard to multiplicity

“…Lahiri [7] which measure how close a shared value is to being shared CM or to being shared IM. We write f , g share (a, k) to mean that f , g share the value a with weight k. Clearly if f ,…”
