proof

assume A2: d is Autonomy of p ; :: thesis: p,d computes {} .--> (Result (p,d))
let x be set ; :: according to EXTPRO_1:def 14 :: thesis: ( x in dom ({} .--> (Result (p,d))) implies ex s being FinPartState of S st
( x = s & d +* s is Autonomy of p & ({} .--> (Result (p,d))) . s c= Result (p,(d +* s)) ) )
assume A3: x in dom ({} .--> (Result (p,d))) ; :: thesis: ex s being FinPartState of S st
( x = s & d +* s is Autonomy of p & ({} .--> (Result (p,d))) . s c= Result (p,(d +* s)) )
then A4: x = {} by TARSKI:def 1;
then reconsider s = x as FinPartState of S by FUNCT_1:104, RELAT_1:171;
take s ; :: thesis: ( x = s & d +* s is Autonomy of p & ({} .--> (Result (p,d))) . s c= Result (p,(d +* s)) )
thus x = s ; :: thesis: ( d +* s is Autonomy of p & ({} .--> (Result (p,d))) . s c= Result (p,(d +* s)) )
d +* {} = d ;
hence d +* s is Autonomy of p by A2, A3, TARSKI:def 1; :: thesis: ({} .--> (Result (p,d))) . s c= Result (p,(d +* s))
thus ({} .--> (Result (p,d))) . s c= Result (p,(d +* s)) by A4, FUNCOP_1:72; :: thesis: verum

A5: {} in dom ({} .--> (Result (p,d))) by TARSKI:def 1;
