    I have partly solved using
    \begin{equation}
    \tag{A.1}
    .
    .
    .
    but must be manually (the numbers)
    Exist any way to do automatic?

there is a question addressing this situation
in the ams author-faq.  go to this site
  http://www.ams.org/author-faq
and search for  "one appendix"  (including
the quotes).  the answer to this question
should help with resolving your problem.
