Abstract
This study establishes the interplay between standard convergence and semi-convergence in topological spaces. Convergence and semi-convergence differences are illustrated with a counterexample. Additionally, an examination of semi-convergence's behavior in irresolute mappings reveals how it affects continuity and function characteristics. Semi-limit points and semi-cluster points are defined in new ways and their features in different topological settings are described by essential theorems. The final section looks at how semi-convergence behaves in product spaces, showing how it interacts with product topologies and establishing important findings that enhance the field's understanding of its study.
