Typically, there is a MATH+ colloquium every other Friday afternoon at Urania
during term time. Friday colloquia usually start at 2:15 pm. Tea and cookies are served before each talk at 1:00 pm. Due to the spread of Covid-19 we will offer only online
talks in the winter semester 2020/21 and summer semester 2021.
MATH+ Fridays in the winter semester 2020/21:
MATH+ Fridays in the summer semester 2021:
What is the concept behind MATH+ Fridays?
The Friday colloquia represent a common meeting point for Berlin mathematics at Urania Berlin: a colloquium with broad emanation that permits an overview of large-scale connections and insights. In thematic series, the conversation is about “mathematics as a whole,” and we hope to be able to witness some breakthroughs. Hardly anyone knows that Grigory Perelman first presented his famous proof of the Poincaré Conjecture to the mathematical public in Berlin, at the PhD student seminar meeting of professors Huisken and Ecker at FU Berlin.
Behind the scenes at MATH+ Fridays, a number of seminars, workshops, courses, and conversation opportunities are on offer. For instance, the lunches prior to the “Sonia Kovalevskaya Colloquia” are a place to discuss the career paths of successful women in mathematics. Seminars and courses that BMS students can request will discuss such topics as presentation training, mathematical typography, library research, and writing style. For these, please have a look at our Academics page.
Summer Semester 2020
We had to cancel the MATH+ Fridays due to the spread of Covid-19 in the Summer Semester 2020. We could offer one online talk instead.
