Dear Zbigniew,
My suggestions are:

(1) Try with the style:
\usepackage{enumerate}
and then for a list:

\begin{enumerate}[1.]
\item ...
\end{enumerate}

(2) In addition, your attempt for
\begin{enumerate}[label=\arabic*.]
 should work with:
\usepackage{enumitem}

(3) You can get the enumeration mode "1." with {enumitem} by adding the
option:

\usepackage[shortlabels]{enumitem}

and then in the list:
\begin{enumerate}[1.]

But I do not know whether \documentclass{amsart} is OK together with the
styles:
enumerate.sty and  enumitem.sty

I've been using the three ways (1)-(3) quite a lot with several
\documentclass, but not with {amsart}.
Let us know, whether the above works with {amsart}. There may be even
better ways, which other people can suggest.

Best Regards,
Roussanka
