Common Fixed Points of Dass-Gupta Rational Contraction and E-Contraction

In this paper, we establish some common fixed-point theorems in supermetric space for Dass-Gupta Rational Contraction, E-contraction, generalized E-contraction and rational Dass-Gupta E-contraction. Additionally, these theorems expand and generalize several intriguing findings from metric fixed-point theory to the supermetric setting. Furthermore, an example is provided to support our results.
