# Seminar: Exponential Integrators

### Registration

Please write a mail to Alexander Zeilmann until April 12th, 2021 if you consider participating.

The first meeting, discussing the seminar and answering questions will take place in the first or second week of the semester.

Afterward, you write a mail with a ranking of your favorite 2 (or more) papers, that the papers can be assigned in case of collisions (otherwise chosen by lot).

### Organization

The seminar is targeted mainly at Master students in mathematics and related areas.

Every Student is supposed to introduce one of the listed papers by a **30-minute talk** (plus discussion). Additionally, write a small **summary with 3 to 5 pages at most** (references excluded). As this is a seminar, you are expected to use English for your summary, slides and talk.

### Schedule

**Submission slides:**one week in advance of your presentation**Submission summary:**one week after your presentation**Talks:**Depending on the number of participants as block seminar or weekly seminar. The seminar will be entirely online.
