let x be set ; for P being non empty strict chain-complete Poset st x is Element of (ConPoset P,P) holds
x is continuous Function of P,P
let P be non empty strict chain-complete Poset; ( x is Element of (ConPoset P,P) implies x is continuous Function of P,P )
assume
x is Element of (ConPoset P,P)
; x is continuous Function of P,P
then
x in ConFuncs P,P
;
then consider y being Element of Funcs the carrier of P,the carrier of P such that
A1:
( x = y & ex g being continuous Function of P,P st g = y )
;
thus
x is continuous Function of P,P
by A1; verum
