Title:	Still more about subfitness
Publication Date:	2014-12-12
Authors:	- Jorge Picado - Ales Pultr
Abstract:	Several features of subfitness are analyzed. Isbell's Spatiality Theorem leads to the concept of T₁-spatiality which is compared with the T_D-spatiality. Subfitness is put into relation with other weak separation axioms (and with the existence of nearness), both in spaces and locales, and seeming discrepancies are explained. A new characteristic of subfitness by means of codensity is presented.
