Some results relating to sum and product theorems of relative $\left(p,q,t\right) L$-th order and relative $\left( p,q,t\right) L$-th type of entire functions

Abstract

Orders and types of entire functions have been actively investigated by many authors. In this paper, we investigate some basic properties in connection with sum and product of relative $\left( p,q,t\right) L${-th order, relative }$\left( p,q,t\right) L${-th type, and relative }$ \left( p,q,t\right) L${-th weak type of entire functions with respect to another entire function where }$p,q\in \mathbb{N} ${ and }$t\in \mathbb{N} \cup \left\{ -1,0\right\} $.
