Few results in connection with sum and product theorems of relative $(p,q)$-$\phi$ order, relative $(p,q)$-$\phi$ type and relative $(p,q)$-$\phi$ weak type of meromorphic functions with respect to entire functions

Orders and types of entire and meromorphic functions have been actively investigated by many authors. In the present paper, we aim at investigating some basic properties in connection with sum and product of relative $(p,q)$-$\phi$ order, relative $(p,q)$-$\phi$ type, and relative $(p,q)$-$\phi$ weak type of meromorphic functions with respect to entire functions.
