| چکیده | ||
| In this article, we systematically develop and extend the concepts and criteria associated with the uniqueness polynomial of meromorphic functions (UPM). Starting from the foundational UPM, we extend the concept to encompass the (reduced) strong uniqueness polynomial for meromorphic functions in a wider sense ((R)SUPMWS), completing this progression. This extension marks a significant advancement in this area of research. The article consolidates and organizes all related definitions of these polynomials in a concise and systematic manner. Furthermore, we classify and analyze various categories of polynomials for degree $n$, where $4 \leq n \leq 6$. | ||
