Uniqueness of meromorphic functions with weakly weighted sharing (Q2847593)

The author introduces a notion of weakly weighted sharing of zeros for meromorphic functions ignoring multiplicities, which extends the same notion counting multiplicity. The author also skilfully elaborates the idea of the notion of multiplicity as used by \textit{R. S. Dyavanal} [J. Math. Anal. Appl. 374, No. 1, 335--345 (2011; Zbl 1202.30054)]. With these notions the authors extends a number of results. Particularly he rectifies several defects in the paper by \textit{C. Wu} et al. [Bull. Aust. Math. Soc. 85, No. 2, 280--294 (2012; Zbl 1246.30064)]. He also obtains more general results than those obtained by Wu et al. in its correct form.
