now
let I be
set ;
let A,
B be
V5 ManySortedSet of
I;
let F be
ManySortedFunction of
A,
B;
let X be
Element of
A;
thus
F .. X is
Element of
B
proof
let i be
set ;
:: according to PBOOLE:def 17
assume A1:
i in I
;
A2:
dom F = I
by PBOOLE:def 3;
reconsider g =
F . i as
Function ;
A3:
g is
Function of
A . i,
B . i
by A1, PBOOLE:def 18;
A4:
A . i <> {}
by A1, PBOOLE:def 16;
A5:
B . i <> {}
by A1, PBOOLE:def 16;
X . i is
Element of
A . i
by A1, PBOOLE:def 17;
then
g . (X . i) in B . i
by A3, A4, A5, FUNCT_2:7;
hence
(F .. X) . i is
Element of
B . i
by A1, A2, PRALG_1:def 17;
