# How can I add these information at the titlepage?

How can I add the name of university and the name of supervisor at the title page of my thesis?

Do I have to add a command before or after \maketitle?

\begin{document}

\title{ Blabla }

\author{ Blabla }

\date{ }

\maketitle


EDIT:

I wrote the following:

\begin{document}

\begin{titlepage}
\begin{center}

\HRule \\[2cm] % Horizontal line
{\huge \bfseries BLaBLa}\\[0.4cm] % Thesis title
\HRule \\[3cm] % Horizontal line

\begin{minipage}{0.4\textwidth}
\begin{center}
\Large{Name}
\end{center}
\end{minipage}\\[2cm]

\begin{minipage}{0.4\textwidth}
\begin{center}
\Large
\emph{Επιβλέπων καθηγητής:}
{name}
\end{center}
\end{minipage}\\[2cm]

\textsc{\Large Μεταπτυχιακή εργιασία}\\[2cm] % Thesis type

\textsc{\LARGE blabla}\\[0.4cm]
\textsc{\LARGE University}\\[2cm] % University name

{\large \today}\\[4cm]

\vfill
\end{center}

\end{titlepage}
\end{document}


but I get the following error for the line

\HRule \\[2cm] % Horizontal line
{\huge \bfseries BLaBLa}\\[0.4cm] % Thesis title
\HRule \\[3cm] % Horizontal line


What does this mean?

You can define a new command \HRule to print a horizontal rule with

\newcommand*{\HRule}{\hrule height 5pt}


You can change the numer after height to get a lower or higher rule.

Your command for a new line with special space to the next line \\[2cm] does then not work. Instead use the command \vspace{2cm}.

With that changes your code compiles with:

\documentclass[chapterprefix=true]{scrreprt}

\newcommand*{\HRule}{\hrule height 5pt} % <===========================

\begin{document}

\begin{titlepage}
\begin{center}

\HRule  % <===========================
\vspace{2cm} % <===========================
{\huge \bfseries BLaBLa}\\[0.4cm] % Thesis title
\HRule  % <===========================
\vspace{3cm} % <===========================

\begin{minipage}{0.4\textwidth}
\begin{center}
\Large{Name}
\end{center}
\end{minipage}\\[2cm]

\begin{minipage}{0.4\textwidth}
\begin{center}
\Large
\emph{Επιβλέπων καθηγητής:}
{name}
\end{center}
\end{minipage}\\[2cm]

\textsc{\Large Μεταπτυχιακή εργιασία}\\[2cm] % Thesis type

\textsc{\LARGE blabla}\\[0.4cm]
\textsc{\LARGE University}\\[2cm] % University name

{\large \today}\\[4cm]

\vfill
\end{center}

\end{titlepage}
\end{document}


and the result:

You asked in a comment for the documentation: If you have a TeX distribution installed on your computer, you can use texdoc koma-script or---if you use a online compiler---search the internet for file scrguide.pdf (German version) or scrguien.pdf (English version) or you can try texdoc.net, but the versions are not always up-to-date.

• @MaryStar You could just as well scrap that horrible Hrule. It is one of the wikibook deseases. – Johannes_B Dec 4 '15 at 15:15
• you could mention texdoc.net, but the versions are not always up-to-date. – Johannes_B Dec 12 '15 at 20:44
