Gürowy, Mustafa Habil2026-04-042026-04-0420252586-9000https://hdl.handle.net/11616/108261In this work, we generalized to topological groupoids that we known the strong morphism for groups. Also we obtained some characterizations of these homomorphisms. Namely, when there is a homomorphism between algebraic structures, there is an important result that arises from this homomorphism between the substructures of these algebraic structures: the correspondence theorem between substructures. From the perspective of groupoid theory, this theorem establishes a bijective correspondence between the subgroupoids of two related groupoids under a surjective homomorphism. © 2025, Thammasat University.
