amsart 和枚举环境

我正在使用 documentclass amsart。现在方程式编号向左对齐，我对此没意见，但让我困扰的是：如果我在环境中有方程式，enumerate它会将方程式相对于整个页面居中。对我来说，这看起来不太好。我如何将方程式相对于环境主体居中enumerate？

只要您不想对方程式进行编号，就可以使用以下命令：

\documentclass{amsart}

%--------------------------------------------------------------------
\newenvironment{shiftequation}
{%
  \par\noindent\begin{minipage}{\linewidth}
  \begin{equation*}
}
{%
  \end{equation*}
  \end{minipage}
}
%--------------------------------------------------------------------
\begin{document}

Here's some text. Here's some text. Here's some text. Here's some
text. Here's some text. Here's some text. Here's some text. Here's
some text. Here's some text.
\begin{equation*}
  \sin^{2} x + \cos^{2} x =
  \int_{0}^{1} \bigl(\sin x + \cos x\bigr)^{4}\, dx +
  \int_{-1}^{1} \bigl(\log(x^{3}) + \sin^{5} (x^{5})\bigr)^{4}\,dx
\end{equation*}

\begin{enumerate}
\item Here's some text. Here's some text. Here's some text. Here's
  some text. Here's some text. Here's some text. Here's some
  text. Here's some text. Here's some text.
  \begin{shiftequation}
  \sin^{2} x + \cos^{2} x =
  \int_{0}^{1} \bigl(\sin x + \cos x\bigr)^{4}\, dx +
  \int_{-1}^{1} \bigl(\log(x^{3}) + \sin^{5} (x^{5})\bigr)^{4}\,dx
  \end{shiftequation}
\item Here's some text. Here's some text. Here's some text. Here's
  some text. Here's some text. Here's some text. Here's some
  text. Here's some text. Here's some text.
\end{enumerate}

\end{document}

唉，如果您尝试使用编号显示执行相同的操作（即，更改equation*为equation），则方程式编号将与环境内文本的左边距对齐enumerate，而不是与整个文本区域的左边缘对齐。
