Hausdorff quasi-distances, periodic and fixed points for Nadler type set-valued contractions in quasi-gauge spaces
(Springer, 2014-12-05)
In a quasi-gauge space (X,P) with quasi-gauge , using the left (right) -families of generalized quasi-pseudodistances on X (-families on X generalize quasi-gauge ), the left (right) quasi-distances DL−Jη ( DR−Jη) of Hausdorff ...
