Rückblick ab 1997

In this seminar, PhD students present to each other their own research or related issues. The intent is to give an insight into the current research of the different research groups of our department or to inform about topics that might interest all PhD students. Therefore, the speakers are encouraged to give a presentation of the topic they are right now dealing with or to present a topic they consider important for mathematics. Each presentation should take 20 minutes + 5 minutes for questions.

It would also be nice if the PhD students could get to know each other better as a result of this seminar.

Even though the seminar primarily addresses PhD students, we also welcome interested master students and postdocs.

For up-to-date information and announcements you may join the PhD seminar mailing list.

Linear elasticity

Within the framework of the Ruth Moufang Colloquium, female mathematicians give scientific lectures. This offer is primarily addressed to students, but also to employees and all interested. The subsequent discussion session will also highlight scientific careers, issues such as work-life balance, etc. The Ruth Moufang Colloquium is designed to give visibility to women at our department and in the field of mathematics in general, and to inform students about their career opportunities. The colloquium is also intended to provide networking opportunities for female students, staff, and professors, and to encourage female students in particular to pursue careers in academia.

The Ruth Moufang Colloqium is organized by the Mathematics Student Council and the Equal Opportunity Officer of the Department.

About Ruth Moufang:

Ruth Moufang (1905 in Darmstadt - 1977 in Frankfurt am Main) was a German mathematician who worked on the study of projective planes and later on applied elasticity theory. In 1936 she habilitated at the Johann Wolfgang Goethe University in Frankfurt am Main, becoming the third woman in Germany to do so in mathematics. As a woman, she was denied the right to teach for a long time. It was not until 1957 that she became the first woman in Germany to be appointed as a full professor of mathematics.
