Meromorphic functions of finite -order and linear Askey-Wilson divided difference equations
Hui Yu, Janne Heittokangas, Jun Wang +1
The growth of meromorphic solutions of linear difference equations containing Askey-Wilson divided difference operators is estimated. The -order is used as a general growth indi…

Difference radical in terms of shifting zero and applications to the Stothers-Mason theorem
Katsuya Ishizaki, Zhi-Tao Wen
In this paper, we study the shifting zeros with its heights and an analogue to difference radical. We focus on the Stothers-Mason theorem by using falling factorials. As applicatio…
