$\boldsymbol{\mathcal I^{*}\text{-}\alpha}$ CONVERGENCE AND $\boldsymbol{\mathcal I^*}$-EXHAUSTIVENESS OF SEQUENCES OF METRIC FUNCTIONS

Abstract

By a metric function, we mean a function from a metric space $(X,d)$ into a metric space $(Y,\rho)$. We introduce and study the notions of $\mathcal I^{*}\text{-}\alpha$ convergence and $\mathcal I^*$-exhaustiveness of sequences of metric functions, and we establish an inter-relationship between these two concepts. Moreover, we establish some relationship between our concepts with some well-established concepts such as $\mathcal I\text{-}\alpha$ convergence and $\mathcal I$-exhaustiveness of sequences of metric functions.
