喜欢这些解决方案之一吗?
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{mathtools, bigstrut}
\DeclarePairedDelimiter{\set}{\{}{\}}
\DeclareMathOperator{\GL}{GL}
\begin{document}
\[ \set*{\begin{tabular}{@{}l@{}}\bigstrut[t]Principal\\$ \GL_N(\mathbf{R}) $-bundles\end{tabular}} =\set*{\bigstrut[t]\begin{tabular}{@{}l@{}}Real Vector Bundles\\of rank $N$ \end{tabular}} \]%
\bigskip
\[ \begin{Bmatrix*}[l]
\bigstrut[t]\text{Principal}\\ \GL_N(\mathbf{R})\text{-bundles}
\end{Bmatrix*} = \begin{Bmatrix*}\bigstrut[t]\text{Real Vector Bundles}\\ \text{of rank }N \end{Bmatrix*}\]%
\end{document}
答案2
此处用 s 完成\stackanchor
。
\documentclass{article}
\usepackage[usestackEOL]{stackengine}
\usepackage{amssymb}
\begin{document}
\[
\renewcommand\stacktype{L}
\strutlongstacks{T}
\left\{
\stackanchor{Principal}{$GL_N(\mathbb{R})$-bundles}
\right\} \longleftrightarrow \left\{
\stackanchor{Real Vector Bundles}{of rank $N$}
\right\}
\]
\end{document}
