How to add acknowledgments in the title (first slide) in a beamer presentation?

Question

I am making a beamer presentation, and want to include text for acknowledgments. I use the tags for the title author institute, but now I want to add more text. Is there a tage for the acknowledgements? Is there a nice way to do so? Below is my code which does not compile due to the acknowledgment text.

\documentclass{beamer}
\usetheme{Warsaw}
 \setbeamertemplate{footline}[page number]
\setbeamercovered{invisible}
\setbeamertemplate{navigation symbols}{} 
\usepackage{graphicx}
\logo{\includegraphics[height=1.2cm]{strathLOGO}}
\title[Short title of the talk]{Understanding Dynamic Interactions}
\author{Alexander V. Mantzaris and Desmond J. Higham}
\institute[]
{
University of Strathclyde, Glasgow. UK\\
\medskip
{\emph{alexander.mantzaris@strath.ac.uk}}
}
\date{\today}

Without the text for the acknowledgments, the presentation compiles. What options are available?

Answer 1

You can use some of the already existing commands to add the information; for example, you can say something like

\date{\today\\[2em]
{\footnotesize Acknowledgement: This work was performed within the
Mathematics of Large Technological Evolving Networks
(MOLTEN) project, which is supported by the Engineering
and Physical Sciences Research Council and the Research
Councils UK Digital Economy programme, with grant ref.

}

Answer 2

Maybe not the perfect solution, but you can add additional information after the preamble and the \titlepage command.

\begin{document} 

\begin{frame} 
\titlepage 

Acknowledgement: This work was performed … 

\end{frame}
