MinionPro 与 amssymb 冲突

Question

我正在使用包。但我需要一些包中提供的MinionPro符号，例如\gnapprox和。\mhoamssymb

好吧，这是我的代码（尽可能简洁）：

\documentclass{report}
\usepackage{MinionPro}
\usepackage{amssymb}

\begin{document}
\[\gnapprox \]

\[\mho \]
\end{document}

但我收到了错误：

Command `\mathfrak' already defined. \DeclareMathAlphabet{\mathfrak}{U}{euf}{m}{n}
Command `\mathfrak' not defined as a math alphabet. ...athAlphabet{\mathfrak}{bold}{U}{euf}{b}{n}
Command `\centerdot' already defined. ...ymbol{\centerdot} {\mathbin}{AMSa}{"05}
Command `\veebar' already defined. ...mbol{\veebar} {\mathbin}{AMSa}{"59}
Command `\barwedge' already defined. ...mbol{\barwedge} {\mathbin}{AMSa}{"5A}
Command `\doublebarwedge' already defined. ...ol{\doublebarwedge} {\mathbin}{AMSa}{"5B}
Command `\circledS' already defined. ...mbol{\circledS} {\mathord}{AMSa}{"73}
Command `\dotplus' already defined. ...mbol{\dotplus} {\mathbin}{AMSa}{"75}
Command `\complement' already defined. ...mbol{\complement} {\mathord}{AMSa}{"7B}
Command `\divideontimes' already defined. ...ol{\divideontimes} {\mathbin}{AMSb}{"3E}
Command `\thicksim' already defined. ...ol{\thicksim} {\mathrel}{AMSb}{"73}
Command `\thickapprox' already defined. ...ol{\thickapprox} {\mathrel}{AMSb}{"74}
Command `\hslash' already defined. ...ol{\hslash} {\mathord}{AMSb}{"7D}

如何正确使用这两个包？

Answer 1

gnapprox也可用于MnSymbol，但与 amssymb 版本略有不同。以下是符号mho位于基线上的变体：

\documentclass[12pt]{article}

\usepackage{graphicx}
\usepackage{MinionPro}
\def\mho{\raisebox{0.96\depth}{\scalebox{1}[-1]{$ \Omega $}} }


\begin{document}

\[ \gnapprox\rlap{\rule[-0.1pt]{1cm}{0.1pt}}{\mho\enspace \Omega

} ]

\end{document}
