Uniqueness and differential polynomials of meromorphic functions sharing a nonzero polynomial
Let $k$ be a nonnegative integer or infinity. For $a\in\mathbb{C}\cup\{\infty\}$ we denote by $E_k(a;f)$ the set of all $a$-points of $f$ where an $a$-point of multiplicity $m$ is counted $m$ times if $m\leq k$ and $k+1$ times if $m>k$. If $E_k(a;f)= E_k(a;g)$ then we say that $f$ and $g$ sha...
