authblktitles
When using authblk and an author/affilliation list like this:
\author[1]{Auth1}
\author[1]{Auth2}
\author[1]{Auth3}
\author[1]{Auth4}
\author[2]{Auth5}
\author[1]{Auth6}
\author[2]{Auth7}
\affil[1]{Affil1}
\affil[2]{Affil2}
The affilliations each show up on their own line:
1 Affil1
2 Affil2
How can I get them on the same line?
1 Affil1 2 Affil2
I would rather patch the authblk package that you are using as follows:
\documentclass[11pt]{article}
\makeatletter
\usepackage{authblk}
\def\@author{}
\renewcommand\@author{\ifx\AB@affillist\AB@empty\AB@author\else
\ifnum\value{affil}>\value{Maxaffil}\def\rlap##1{##1}%
\AB@authlist \\*[0.3cm]On behalf of a great Team!\\[\affilsep]\AB@affillist
\else \AB@authors\fi\fi}
\makeatother
\title{Brief Article}
\author[1]{author1}
\author[1]{author2}
\affil[1]{Institute of Nowhere}
\author[2]{author3}
\affil[2]{Institute of Somewhere}
\begin{document}
\maketitle
\end{document}
Adjust spacing etc to suit!
In beamer, the institute \and is defined as
\def\beamer@andinst{\\[1em]}
so that it inserts a line break and leaves a 1em vertical gap between entries. Mere redefine this as
\makeatletter
\def\beamer@andinst{\quad}
\makeatother
to insert a 1em horizontal gap between entries:
\documentclass{beamer}
\title{Title goes here}
\author[shortname]{Author1 \inst{1} \and Author2 \inst{2} \and Author3 \inst{3}}
\institute[shortinst]{\inst{1} Affil1 \and \inst{2} Affil2 \and \inst{3} Affil3}
\makeatletter
\def\beamer@andinst{\quad}
\makeatother
\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}

In this way the affiliations will separated by an em-dash surrounded by spaces. Choose what suits you.
