let IAlph, OAlph be non empty set ; for M1, M2 being non empty finite reduced connected Mealy-FSM over IAlph,OAlph holds
( M1,M2 -are_isomorphic iff M1,M2 -are_equivalent )
let M1, M2 be non empty finite reduced connected Mealy-FSM over IAlph,OAlph; ( M1,M2 -are_isomorphic iff M1,M2 -are_equivalent )
thus
( M1,M2 -are_isomorphic implies M1,M2 -are_equivalent )
by Th63; ( M1,M2 -are_equivalent implies M1,M2 -are_isomorphic )
A1:
M2, the_reduction_of M2 -are_isomorphic
by Th46;
assume
M1,M2 -are_equivalent
; M1,M2 -are_isomorphic
then A2:
the_reduction_of M1, the_reduction_of M2 -are_isomorphic
by Th65;
M1, the_reduction_of M1 -are_isomorphic
by Th46;
then
M1, the_reduction_of M2 -are_isomorphic
by A2, Th42;
hence
M1,M2 -are_isomorphic
by A1, Th42; verum
