它在这里(该\otherbeta
命令特定于fourier
字体,在数学中有一个直立的小写希腊字母):
\documentclass{article}
\usepackage{fourier}
\usepackage{showframe}
\renewcommand{\ShowFrameLinethickness}{0.3pt}
\usepackage{amsmath}
\newcommand*{\dd}{\mathop{}\!\mathrm{d}} %% differential symbol for integrals
\begin{document}
\[ U(1,\otherbeta) = \int_{1-p}^p \max\nolimits_B\bigl\{pu\bigl(w + 1-P)B\bigr) + (1-p)u(w-PB)\bigr\}\dd M_{\otherbeta}(P) \]%
\end{document}
