The design of the lecture follows a form that is typical in Germany. There is one lecture per week with one exercise sheet that aims to deepen the understanding of the content of the lecture. We suggest handing out the exercise sheet right after the lecture and then discuss it in a separate session in the following week. However, it is also possible to do the lecture as a block course with multiple lectures and exercise sheets a day. It is possible to discuss the whole content within one week.
The content of the repository is structured as follows:
lectures→ Lecture Units- For each lecture there is the PowerPoint source file
- There further is a small slide set
OpenFHE_Code_Example.ptxthat contains a brief example for the usage of the OpenFHE library - The lecture contains a set of toy examples. They are provided in the files starting with
Toy_. The presentation slides contain a note in the top right-hand corner indicating where we consider it appropriate to present them during the leture
exercises→ Exercise Sheets- For each exercise sheet there is one director
- Each directory contains the LaTeX source file for the exercises. There is no LaTeX preamble but the sources can be easily copied into any template for exercise sheets
- Each directory also contains a PDF file that gives an idea how the exercises can look like. It is a slightly modified design from the one that was used for the original three courses in 2024/25
