正如 David Carlisle 在评论中提到的,您喜欢的文章是使用amsart
document 类生成的。以下代码完全重现了您发布的屏幕截图的前几行:
\documentclass{amsart}
\title{Verdier Duality}
\author{Akhil Mathew}
\usepackage{geometry}
\begin{document}
\maketitle
\section{Introduction}
Let $M$ be a smooth, compact oriented manifold of dimension $n$, and let $k$ be a field.
Recall that there is a natural pairing in singular cohomology
\end{document}
