The evaluation is based on attendence and a written exposition on a topic or paper in the field. Some example articles and notes are listed below. This may include filling in details and example calculations that are often omitted in research papers. It may also involve looking up references and putting the work of a particular paper into perspective of other papers.

Draft submission deadline: 31. December 2022*

Final submission deadline: 31. January 2023*

*submission before midnight means at the latest 11:59pm




The design of this course is inspired by the course on generalized complex geometry taught by Marco Gualtieri in 2015 at the University of Toronto.
