Abstract :

This paper advances the theory of bipolar fuzzy sets by integrating them into the structure of IUPalgebras. It introduces and formalizes the concepts of bipolar fuzzy IUP-subalgebras, filters, ideals, and strong ideals, establishing their foundational properties through rigorous theorems and counterexamples. The interplay between these algebraic structures and their level cuts is examined to provide a nuanced understanding of dual-valued uncertainty in abstract logic. In addition to its theoretical contributions, this research holds significant educational value, particularly for science-oriented learning environments where mathematical abstraction and logical reasoning are cultivated. By translating complex fuzzy-algebraic concepts into structured and illustrative forms, the study offers a meaningful framework that can inspire student-led investigations and enrich curricula in research-focused schools. Furthermore, it encourages collaboration between educators and researchers in developing accessible tools and learning modules that bridge advanced mathematical logic with real-world inquiry, promoting a more inclusive and research-driven academic atmosphere.
