A “generalized quotient” of each object is defined without making the usual assumption that for each fixed g âˆˆ S, λ(., g) : X â†’ X is an injection.}, number={2}, journal={Applied General Topology}, author={Richardson, Gary and Boustique, H. and Mikusinski, Piotr}, year={2013}, month={Sep.}, pages={67–88} }
