I have a beamer document with
\beamerdefaultoverlayspecification{<+->}
in the preamble to make \items appear separately. However, this seems to also make \bibitems
appear separately. How can I switch back to 'normal' within the document, such that all bibitems appear on one slide?
You can change the default overlay specification before the bibliography:
\documentclass{beamer}
\usepackage{biblatex}
\addbibresource{biblatex-examples.bib}
\beamerdefaultoverlayspecification{<+->}
\begin{document}
\begin{frame}
\begin{itemize}
\item content...
\item content...
\end{itemize}
\end{frame}
\beamerdefaultoverlayspecification{}
\begin{frame}
\nocite{knuth:ct,angenendt}
\printbibliography
\end{frame}

I would like to change the font of the alerted text in my beamer, I want it to be in bold, in both text and math mode. I tried using boldmath but it doesn't work :
\begin{frame}{Test}
\setbeamercovered{invisible}
\setbeamercolor{alerted text}{fg=vertf}
\setbeamerfont{alerted text}{family=\sffamily, series=\bfseries\boldmath}
$$\alert<2>{x} + \alert<3>{y} + \alert<4>{z}$$
\begin{itemize}
\item <2-| alert#2>x
\item <3-| alert#3>y
\item <4-| alert#4>z
\end{itemize}
\end{frame}
You could work around the problem with something like this:
\documentclass{beamer}
\setbeamercovered{invisible}
\setbeamercolor{alerted text}{fg=green}
\setbeamerfont{alerted text}{series=\bfseries\boldmath}
\renewcommand<>{\alert}[1]{%
\ifmmode\text{%
\begin{alertenv}#2\relax$#1$\end{alertenv}%
}%
\else%
\begin{alertenv}#2\relax#1\end{alertenv}%
\fi%
}
\begin{document}
\begin{frame}
\frametitle{Test}
\[
\alert<2>{x} + \alert<3>{y} + \alert<4>{z}
\]
\begin{itemize}
\item <2-| alert#2>x
\item <3-| alert#3>y
\item <4-| alert#4>z
\end{itemize}
\end{frame}
\end{document}
I'm trying to customize my itemize list in a Beamer slide using the noitemsep and topsep settings available in the enumitem package. However, using enumitem with Beamer causes the bullet points to disappear (images attached below). I also came to know that enumitem isn't really compatible with Beamer, and should not be used alongside the enumerate package, but I can't figure out what alternatives are available for my use case.
When I don't use enumitem
\begin{frame}
\begin{itemize}
\item Apples
\item Oranges
\item Bananas
\end{itemize}
\end{frame}
Output (contains bullet points):
When I use enumitem:
\usepackage{enumitem}
\begin{frame}
\begin{itemize}[noitemsep]
\item Apples
\item Oranges
\item Bananas
\end{itemize}
\end{frame}
Output (the bullets have disappeared):
Any hints regarding what settings I should use with enumitem when using Beamer, or what other alternative packages I can use (which is more compatible with Beamer) which can fulfill my objective, would be greatly appreciated.
Don't use enumitem with beamer, it is not compatible.
You can adjust the spacing in various ways, either locally or globally.
\documentclass{beamer}

I have a code below. And I want to highlight the current formula in red while others are in black. many thanks in advance.
\documentclass{beamer}

\pause \item \textcolor{red}{redbla but the I want to see the second redbla in \textcolor{black}{black.}}
\end{itemize}
\end{frame}
\end{document}
You can highlight the current item in red by using the <alert#+> overlay specification:
\documentclass{beamer}
\begin{document}
\begin{frame}
\frametitle{Frame Title}
\begin{itemize}[<alert#+>]
\item bla
\item redbla
\item redbla but the I want to see the second redbla in black.

I am trying to insert a figure but its caption is transparent in the current page. how to prevent this? many thanks in advance.

It looks like
The caption is transparent because you are using \setbeamercovered{transparent}. You have two options to avoid the transparent caption:
immediately show the images and caption by avoid the \pause in front of them
switching to \setbeamercovered{invisible} either temporarily or for the whole presentation to delay the images and caption to the next overlay:
\documentclass{beamer}
\usetheme{Ilmenau}
\setbeamercovered{transparent}
\setbeamercolor*{item}{fg=blue}

Some other comments:
you don't need \usepackage{hyperref}, beamer already loads it
I'd be wary to use \hypersetup{urlcolor=blue} with beamer, this can lead to strange alternations to the carefully constructed colour themes of beamer in places one would never expect
If your tex distribution was updated within the last 5 years or so, you don't need \usepackage[utf8]{inputenc}, that's now the default
If you just want to change the font size of the caption, you don't actually need the caption package, beamer has its own mechanism to control the size of captions
Instead of \begin{frame}{...} I would use \frametitle{...}. That's much more flexible and powerful
If you specify both the width and height of your images, they will end up distorted. Please consider adding the keepaspectratio option to avoid this
to avoid manually repeating the same frame title several times ("Probleme heutiger Computer (3)") you could use overlays and add the slide in frame counter to the frametitle
I am using Latex for the first time and I am preparing a slide using 'beamer'. What happening is that some of my citations, tables and long equations are exceeding beyond the text width, though it wasn't the problem when the document class was 'article'. My tables aren't long, as one of them has only 3 rows and 6 columns.
The latex codes are
\documentclass[9pt]{beamer}
\mode<presentation> {
\usefonttheme{serif}
\usetheme{Madrid}
\definecolor{BlueGreen}{cmyk}{0.85,0,0.33,0}
\colorlet{beamer#blendedblue}{BlueGreen!120}}
\usepackage{booktabs}
\usepackage{caption}
\hypersetup{pdfnewwindow}
\setbeamertemplate{caption}[numbered]
\setbeamerfont{frametitle}{size=\footnotesize}
\setbeamertemplate{navigation symbols}{}
\setbeamercolor{postit}{bg=violet!110}
\usepackage{ragged2e} %new code
\addtobeamertemplate{block begin}{}{\justifying}
\usepackage{textpos}
\begin{document}
\begin{frame} \frametitle{\textbf{{\Large Objective}}}
\begin{itemize}
\justifying
\item This package gives you easy access to the Lorem Ipsum dummy text; an option is available to separate the paragraphs of the dummy text. This text \cite{kumar2015method}.
\item The long equation is:
\begin{equation}
A(\theta,\alpha) = \dfrac{ A*{-(\alpha*A)}\beta*{(\delta-1)} \left(A* \hspace{1mm}\hspace{1mm}C^{-A Z_{H}} \hspace{1mm}C^{-C^{-A *Z_{H}}} \prod_{i=1}^{m-1} \left( \dfrac{ A \hspace{1mm}C^{-A* Z_{u(i)}} C^{-C^{-A* Z_{u(i)}}}}{1- \frac{1}{C-1} (C^{1-C^{-A Z_{u(i)}}}-1)}\right) \right) }{ \int_{0}^{\infty} C^{-(\alpha *A)}(A^{(\beta-1)} \left( A* \hspace{1mm}\hspace{1mm}C^{-A Z_{H}} \hspace{1mm}C^{-C^{-A Z_{H}}} \prod_{i=1}^{B-1} \left(\dfrac{ A \hspace{1mm}C^{-A Z_{u(i)}} C^{-C^{-A* Z_{u(i)}}}}{1- \frac{1}{C-1} (C^{1-C^{-A* Z_{u(i)}}}-1)}\right) \right) A} .
\end{equation}
\end{itemize}
\end{frame}
\bibliography{ref}
\bibliographystyle{plainnat}
\end{document}
And the contents of the .bib file is:
#article{kumar2015method,
title={This is the title of the article},
author={Kumar, Dinesh and others},
journal={This is Journal},
volume={2},
number={3},
pages={150-180},
year={2015}
}
If you use the plainnat bib style, you should also load the natbib package. This will automatically allow line breaks
you don't need the caption package, beamer provides it's own mechanism to customise captions
you must place the bibliography inside a frame
for the very large equation, I would suggest to replace the fraction with (...) \times (...)^{-1}, this way you can split it over multiple lines. In addition you'll probably want to use a smaller font size and maybe remove all the manual spaces.
