这看起来不仅仅是tcolorbox
一个beamer
块:
\documentclass{beamer}
\usepackage[most]{tcolorbox}
\usepackage{amsmath}
\definecolor{cream}{RGB}{255,255,221}
\begin{document}
\begin{frame}
\begin{tcolorbox}[colback=cream, title=Definition, colbacktitle=black!15, coltitle=black]
\begin{align*}
\beta^+(u) & =\limsup_{y\rightarrow\infty} \max_{(a_p)}\left(\left|[0,y]\in S_{y^{1/u}}\right|\frac{\log(y^{1/u})}{e^{-\gamma}y}\right),\\
\beta^-(u) & =\liminf_{y\rightarrow\infty} \max_{(a_p)}\left(\left|[0,y]\in S_{y^{1/u}}\right|\frac{\log(y^{1/u})}{e^{-\gamma}y}\right).\\
\end{align*}
\end{tcolorbox}
\end{frame}
\end{document}
