There is no official template for theses or presentations in LaTeX. There are however some inofficial templates that comply with most of the style guidelines:
- Malte Schmitz offers some templates at github. For example, the thesis template at http://github.com/malteschmitz/latex-thesis is a generic template that can be used at any institute by replacing the logo. Notice, that each institute may require further design adaptations or a different citation style.
- For students at the ISP, you may use the thesis template and the presentation template offered by René Schönfelder. The templates are password protected, so you will need to ask your advisor for access.
