In this paper, we investigated two kinds of structured groups: first, those in which the binary internal relation is an equivalence relation, where we showed that the quotient set acquires a group structure, leading to a characterization of its normal subgroups. As a consequence, we obtained that group quotients by congruencies are equivalent to group quotients by normality. Additionally, we proved that the quotient set of a topological group with a compatible equivalence relation is also a topological group whose canonical projection is an open map. The second type of structured groups, we considered, are those with a partial order relation. In this case, we identified nonrestrictive sufficient conditions for the order topology to define a monoid topology, hence, a group topology.}, publisher = {American Mathematical Society}, keywords = {topological group}, keywords = {ordered group}, keywords = {order topology}, title = {Generalized topological ordered groups}, doi = {10.3934/ERA.2026147}, author = {García Pacheco, Francisco Javier and Moreno Frías, María Ángeles and Rahbariyan, Sakineh}, }
