Moreover, we prove that, given a paratopological group G, the paratopological groups Reg(G·) and (Reg(G))· are topologically isomorphic.Reconocimiento - No comercial - Compartir igual (by-nc-sa)Hartman-MycielskiSemiregularizationTi-reflectionSemitopological groupParatopological groupArtículo10.4995/agt.24809Abierto1989-4147
