Abstract
The elusive nature of dark energy, driving the accelerated expansion of the universe, remains one of the most profound mysteries in modern cosmology. In this literature review, we undertake a comprehensive examination of the mathematical models proposed to elucidate the properties and behavior of dark energy. Beginning with an overview of the observational evidence for dark energy, we delve into the diverse array of theoretical frameworks developed to describe this enigmatic phenomenon. Through a critical analysis of peer-reviewed literature, observational data, and theoretical constructs, we explore the strengths, limitations, and implications of various mathematical descriptions of dark energy. Our review encompasses both phenomenological parametrizations and fundamental physics-based models, providing insights into the intricacies of dark energy dynamics. By synthesizing the current state of knowledge, we aim to contribute to the ongoing discourse surrounding dark energy and its implications for our understanding of the universe. This review serves as a valuable resource for researchers and enthusiasts alike, fostering further inquiry and advancement in the captivating field of cosmology
