theorem Th58:
Integral(M,(abs(X-->0)) to_power k) = 0
proof
A1:for x be object st x in dom (X-->0) holds 0 <= (X-->0).x;
   then Integral(M,(abs(X-->0)) to_power k)
     = Integral(M,(X-->0) to_power k) by Th14,MESFUNC6:52
    .= Integral(M,(X-->0)) by Th12
    .= Integral(M,abs(X-->0)) by A1,Th14,MESFUNC6:52;
   hence thesis by LPSPACE1:54;
end;
