A1: the carrier of SC c= the carrier of (MonMaps (S,T)) by YELLOW_0:def 13;
A2: the carrier of SC c= the carrier of Sm

proof

let a be object ; :: according to TARSKI:def 3 :: thesis: ( not a in the carrier of SC or a in the carrier of Sm )
assume A3: a in the carrier of SC ; :: thesis: a in the carrier of Sm
then reconsider f = a as Function of S,T by A1, WAYBEL10:9;
f is continuous Function of S,T by A3, WAYBEL17:def 2;
then a is Element of Sm by Th21;
hence a in the carrier of Sm ; :: thesis: verum

end;

the carrier of Sm c= the carrier of SC
