Induced topologies for quasigroups and loops

Kenneth Paul Baclawski and Kenneth Kapp

Vol. 45 (1973), No. 2, 393–402

The concept of a [semi] topological quasigroup is defined and the notions of induced groupoids and isotopes are extended to the topological case. Necessary and sufficient conditions are found in order for a continuously induced isotope of a semitopological quasigroup to be a semitopological quasigroup. Given an injection i of a topological space (A,𝒜) into a set S acted on by a group, G, a topology 𝒯A on S is introduced in a natural fashion under which i is continuous. When S = Q is itself a semitopological quasigroup and G is generated by the left or right translations of Q the continuity or openness of i can be checked by comparing the topology 𝒯A with that of Q. In particular this method is applied in §3 to the study of topologically invariant subloops.
