在 itemize 环境中设置中断

Question

我有多个大型 itemize 环境，其中一般环境如下

\subsection*{Page }
\begin{itemize}
     \item
     \hfill
     \begin{tcolorbox}
          \blindtext
     \end{tcolorbox}
     \blindtext
\end{itemize}

我遇到的问题是存在如下中断：

对应的代码是

\item 
    \hfill
    \begin{tcolorbox}
        \ldots for $dK \pm Kd$ maps closed forms to exact forms \ldots
    \end{tcolorbox}
    We check that $dK \pm Kd$ takes closed forms to exact forms. If $\o$ is a closed form then $d\o = 0$, and
    $$(dK \pm Kd)(\o) = dK\o \pm Kd\o = dK\o.$$
    The form $dK\o$ is exact because it's the image of $K\o$ under $d$.

和

    \subsubsection*{Page 16}
\begin{itemize}
    \item
    \hfill
    \begin{tcolorbox}
    \begin{center}
        $\displaystyle H^{q} = \begin{cases} \R & q = 0 \\ 0 & q > 0 \end{cases}$
    \end{center}
    \end{tcolorbox}
    $H^{q}$ means $H^{q}(\R^{0})$ where $\R^{0}$ is the one point space. Notice that we have no local coordinates in this case.

我想在序言中设置一个设置，以停止这样的中断并将整个注释移至下一页。这可能吗？

Answer 1

问题在于 之前的换行符tcolorbox。如果您减小宽度并使用\centering而不是center环境，则框将与项目符号保持在同一行。我不确定您想要什么垂直定位；下面给出了一个建议。

\documentclass{article}

\usepackage{tcolorbox,amsmath,amssymb}

\newcommand{\R}{\mathbb{R}}

\begin{document}

\subsubsection*{Page 16}
\begin{itemize}
\item
  \begin{tcolorbox}[width=\linewidth,baseline=\tcbtextheight+\baselineskip]
    \centering
    $\displaystyle H^{q} =
    \begin{cases}
      \R, & q = 0, \\
      0, & q > 0.
    \end{cases}$
  \end{tcolorbox}
  $H^{q}$ means $H^{q}(\R^{0})$ where $\R^{0}$ is the one point
  space. Notice that we have no local coordinates in this case.
\end{itemize}

\end{document}

您可能需要看看tcbitemize环境，它可能更适合您的目的。
