xypic:\varprojlim 和 \varinjlim 不起作用

LyX 拒绝编译任何包含 \varprojlim $\varprojlim$ 和 \varinjlim $\varinjlim$ 的 xymatrix。（如何）可以修复此问题吗？

编辑：这是一个无效代码的示例。

我必须[hebrew]从您的示例中删除标题中的希伯来语文本，才能使其在我的 TeXlive 2013 安装中正常工作。我意识到您可能只需要在里面使用\protect\varinjlim和。以下方法对我有用：\protect\varprojlim\xymatrix

没问题。正如 egreg 所说，总是举个简单的例子。全知水晶球在现实生活中并不存在。

这对我来说很好

\documentclass[a4paper]{memoir}
\usepackage[all]{xy}
\usepackage{amsmath,amssymb}
\begin{document}
\begin{equation*}
  \xymatrix{ 
    \varprojlim x  \ar[r] \ar[d] & \varinjlim  y  \ar[d] \\
    \varprojlim x  \ar[r] & \varinjlim  y \\
  }
\end{equation*}
\end{document}
