Value-sharing problem for p-adic meromorphic functions and their difference operators and difference polynomials
We discuss the value-sharing problem, versions of the Hayman conjecture, and the uniqueness problem for p-adic meromorphic functions, as well as their difference operators and difference polynomials.Дослiджено питання про спiльнi значення i єдинiсть та аналоги гiпотези Хеймена для p-адичних мероморфних функцiй та їх рiзницевих операторiв i рiзницевих полiномiв
On the stability of unique range sets for meromorphic functions
For a set S we construct a complex space Z sub S such that S is a unique range set for meromorphic functions (URS) if and only if Z sub S is hyperbolic. A consequence of this result is that the set of URS with n elements (considered as a subset of C sup n) is open, and then the small deformations of Yi's and Frank-Reinders' sets are URS
