MaRDI QIDQ6534204


Description: Every extended metric space (e-metric space) is paracompact. Specifically, for any open cover of an e-metric space, there exists a locally finite open refinement. This theorem guarantees that extended metric spaces satisfy a fundamental property in topology, making them suitable for applications requiring locally finite refinements of open covers.
