let X be non empty TopSpace; for Y being non trivial monotone-convergence T_0-TopSpace st oContMaps X,Y is complete & oContMaps X,Y is continuous holds
InclPoset the topology of X is continuous
let Y be non trivial monotone-convergence T_0-TopSpace; ( oContMaps X,Y is complete & oContMaps X,Y is continuous implies InclPoset the topology of X is continuous )
assume A1:
( oContMaps X,Y is complete & oContMaps X,Y is continuous )
; InclPoset the topology of X is continuous
then
Sierpinski_Space is_Retract_of Y
by Th25, Th26;
then A2:
( oContMaps X,Sierpinski_Space is complete & oContMaps X,Sierpinski_Space is continuous )
by A1, Th24;
InclPoset the topology of X, oContMaps X,Sierpinski_Space are_isomorphic
by Th6;
hence
InclPoset the topology of X is continuous
