On the ESQ Property of Certain Representations of Metacyclic Groups [PDF]
Advances in Group Theory and Applications, 2017 A group representation is said to have the ESQ property if it is isomorphic to a quotient of its own exterior square. Let us denote the semidirect product of cyclic groups $Z_p\rtimes Z_q$ by $F_{p,q}$, where p is a prime and $q | p − 1$.

Further Results about a Special Fermat-Type Difference Equation
Journal of Function Spaces, 2020 In this paper, we prove the difference equation Fz3+ΔcFz+c3=1 does not have meromorphic solution of finite order over the complex plane C. We also discuss an application to the unique range set problem.
