I have set my beamer file with these settings :

\documentclass[compress]{beamer}
\mode<presentation>
{
\usetheme{PaloAlto}
\useoutertheme[footline=authortitle]{miniframes}
}
\usepackage{array}
\usepackage{hyperref}
\usepackage{beamerthemesplit,amsthm,amsmath}
\usepackage{amsmath,amssymb,graphicx,tikz,amsthm,dirtytalk,mathtools}
\usepackage{MnSymbol,blindtext,hyperref,geometry}

\geometry{papersize={12.8cm,10cm}}
\PassOptionsToPackage{height=1cm}{beamerouterthemesidebar}

\DeclareMathOperator{\Aut}{Aut}
\DeclareMathOperator{\Irr}{Irr}
\DeclareMathOperator{\spec}{Spec}
\DeclareMathOperator{\L-spec}{L-Spec}
\DeclareMathOperator{\Q-spec}{Q-Spec}
\DeclareMathOperator{\cent}{Cent}



But, still the results comes out to be this:
[![enter image description here][1]][1]

**I want that top bar that shows the Title and the Section to go away and only the Frame Title to appear**. How can I do that ?

I thought that \setbeamertemplate{headline}{} would do the trick but it doesn't.

Thanks!

The layout you want to achieve sounds pretty much like off the rack PaloAlto theme, so you just need to remove all other themes you load after PaloAlto:


\documentclass[compress]{beamer}
\mode<presentation>
{
\usetheme{PaloAlto}
%  \useoutertheme[footline=authortitle]{miniframes}
}
\usepackage{array}
%\usepackage{hyperref}
%\usepackage{beamerthemesplit,amsthm,amsmath}
\usepackage{
%amsmath,amssymb,graphicx,
tikz,
%amsthm,
dirtytalk,mathtools}
\usepackage{MnSymbol,blindtext,
%hyperref,geometry
}

%\geometry{papersize={12.8cm,10cm}}
%\PassOptionsToPackage{height=1cm}{beamerouterthemesidebar}

\begin{document}
\section{test}
\begin{frame}
\frametitle{title}
content...
\end{frame}
\end{document}

*(I also commented out a couple of unnecessary packages which beamer already loads for you)*
