The Devanagari Konkani greeting in the frame title requires \textsc{Xe}\LaTeX\ to compile. Just \LaTeX\ wouldn't suffice.

\section{Bibliography}
\begin{frame}{Some Literature Survey} For the first citation, one needs a \texttt{\textbackslash citet*} to lay out a full author list, as \citet*{annie1} demonstrate, and this is not different for citing documents that have less than three authors as in \citet{shildesthesis}. One need not worry about citing several documents together, as in \citet{madhsardthesis,mcderm} or \citep{sinhala1,sinhala2} or \citealp{sampson1,sampson2}. One can also choose to cite Wirth\citeyearpar{wirth} with the year given differently.
