Namely, triangle inequality in defined will have form, d ≤ z + for all ∈ X . Examples spaces that are not extended sense Kamran et al. given to show our is different. A Banach contraction principle on and an example illustrate usefulness structure extension.

The present paper aims to define three new notions: Θ e -contraction, a Hardy–Rogers-type and an interpolative -contraction in the framework of extended b-metric space. Further, some fixed point results via these notions study endeavors toward feasible solution would be suggested for nonlinear Volterra–Fredholm integral equations certain types, as well fractional differential equation Caputo type by using obtained results. It also considers numerical example indicate effectiveness this technique.
