从幻灯片中删除标题

Question

我正在尝试制作演示文稿。我想删除出现在每张幻灯片页脚中的超长标题。我该怎么做？我使用了以下代码。

\documentclass[english,svgnames,notes=hide,12pt]{beamer}
\usepackage{amssymb,latexsym,amsmath}
\usetheme{Copenhagen}
\usecolortheme{beaver}
\setbeamertemplate{headline}

\def\presentationtitle{Asymptotic symmetries at timelike infinity}

\title{\large\presentationtitle}
\author{Aniket Khairnar}

\date{}

\begin{document}

\thispagestyle{empty}

\begin{frame}
 \titlepage 
\end{frame}

\begin{frame}
   \frametitle{Why?}
\begin{itemize}
\item Reason for studying asymptotic symmetries.
\item Study of BMS group at null and spacelike infinity.
\item Statements on massive particle soft theorems
\item Holographic principle

\end{itemize}
\end{frame}
\end{document}

Answer 1

一种方法是给短标题选项添加一个空值：\title[]{\large\presentationtitle}
