On Modular $b-$Suprametric Spaces and Fixed Point Results
Abstract
In this paper, we introduce modular $b$-suprametric spaces, which extend the classical modular framework by combining a scaling parameter with a nonlinear interaction term. This structure unifies and generalizes modular metric, modular $b$-metric, and modular suprametric spaces. Within this setting, we establish a Banach-type fixed point theorem under natural conditions, including the $\Delta_2$ property and the non-increasing behavior with respect to the modular parameter. As an application, we consider a nonlinear Volterra integral model arising in drug absorption with memory effects and prove the existence and uniqueness of a stable solution. These results show that the proposed framework is suitable for analysing nonlinear problems involving memory and interaction phenomena.
