With three new service assistants starting on the Mathematics Library team in December, our hours of operation can be extended again.

From Monday, 5^th of Dec '22:

Mondays - Fridays: 09:00 - 21:00
Saturdays - Sundays: -closed-

Please note that due to energy saving measures, the Math Building will not be accessible on weekends until further notice. In addition, there will be a year-end closing period:

From 17^th of Dec '22 to 8^th of Jan '23, the Mathematics Library will be closed.

Uni-Shop on campus: From now on, products from the official TU Berlin store can also be purchased at the Mathematics Library. We offer the following selection:

• Transparent library bag
• Organic gym bag
• TU Berlin mug (red)
• Kambukka thermo mug 500 ml
• TU sports socks
• Writing pad DIN A5
• Pen
• "TUmate" seed pack

The product range will possibly be extended. Please note that only card payment is possible.

Just in time for the start of the semester, we can offer six improved workstations, where you can participate in online lectures and video conferences.

The only rules to be observed are:

1. sound exclusively through your own headphones
2. speak quietly and
3. vacate seat if necessary

Table bookings are not possible. The workstations can be found between our journal shelves. A big "thank you" goes to the carpenters of the TU Berlin, who built the seats during the summer.

We cordially invite all mathematicians, students and the public interested in art to our semester kick-off on Tuesday, October 18, 2022 at 6 pm in our library.

On that evening, the Institute of Mathematics will open the exhibition Bauhaus Dessau by Swen Bernitz. The conceptual photographic project shows the Bauhaus buildings in Dessau in four partial series in the artistic style of various Bauhäusler: Marianne Brandt, Lyonel Feininger, Wassily Kandinsky and László Moholy-Nagy.


In the edited photographs by Swen Bernitz, the art concepts or working methods of the protagonists and the pioneering architecture are combined to create a new and creative view of the Bauhaus.

Looking forward to an interesting and convivial evening with art, wine and good conversation:

Stefan Felsner, Executive Director of the Institute for Mathematics
Jan Erdnüß, Head of the Mathematical Library

It's getting colder outside, so we can no longer leave the windows open permanently. So we're ventilating regularly again. It gets a little colder in the reading rooms now and then.

A hot tea does good in that situation. From now on, our little "tea station" is back in operation. We offer hot water and various sorts of tee at the service desk. We kindly ask everyone to bring their own cups and to feel free to leave some change in the designated pot every now and then, so that we can buy new tea bags.

We rearranged the shelves in the summer and made them more structured, so that there is now more space for the textbooks. They can be borrowed from us either for four weeks or for an entire semester. Most of the titles are also available as e-books and good supplements to the lecture notes in the basic math courses LinA I+II, Ana I-III, CoMa, DGL, WT...

Please note that the Mathematical Library will be closed for two and a half weeks. From 8/15 - 8/31/2022, the use of the reading rooms is not possible.

If you need literature, please contact us by phone: 030-314 22331 or email: library (at) math.tu-berlin.de and we will find an appointment. Books can be returned during the closing time at the University Library or in a return box at the gatekeeper's lodge in the MA building.

A good summer time wishes the team of the math library.

The current art exhibition Embroidery : Density and Transparency is on view in the Mathematics Library until August 12, 2022. We show works of the fiber artist Javiera González Zarzar. In her artwork, embroidery takes on an abstract dimension that focuses on visualizing the inherent properties of materials.The exhibition is open free of charge during opening hours.

Exhibition Press Text (german and english)

Some books are considered standard reference works because they are well known and used all over the world. For Computer-oriented Mathematics, the "Cormen" (Introduction to Algorithms) is one of these standard works. Internationally, the work is often abbreviated as "CLRS", the four initials of the authors Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein.The 4th edition of the work has now recently been published and is available for loan from our textbook collection. Link to the title. The eBook version of the latest edition is also available on the campus network of the TU Berlin: Link to full text.

For the second time, the event "The Aftermath" will take place at the Math Library. Three mathematicians will take questions from students on the podium. Afterwards there is time for informal exchange with cold drinks and music.

** On July 7, 2022 at 7:00 pm**

All mathematics students are invited to attend.
Admission is free, no registration is required. Please wear an FFP2 mask.
Normal library service will end at 6:00pm that day.

Invitation text from the organizers:

You can do anything with math, they told us.

But at the same time we see very many graduates starting at banks or insurance companies, as it is written in every university guidebook under *jobs for mathematicians*. Or they stay in math research. So where are all the other options? We wanted to talk to people who have taken a different path and answer honestly when we ask what it's really like in their job. Because there wasn't an event like this before, we organized it.

Two years ago, we started inviting people to speak with us who, for example, worked for the weekly newspaper DIE ZEIT after graduating from math school or simulated how the Energiewende could work. After a corona-related break, our panel The Aftermath goes into the second round.

We welcome TU President Prof. Dr. Geraldine Rauch, environmental economist Prof. Dr. Linus Mattauch and McKinsey consultant and PhD student on human-robot interactions Franziska Wolf.

We'll ask them how they got to what they do, what math they still need in their jobs, if they are happy - and of course much more.

After the panel interview, you can chat with our guests and with each other while a fellow student plays ambient music he produced especially for the evening. We are organizing this event for us and for you in our free time and we get no money for it.

We would like to thank the Mathematics Library for hosting the event for the second time and for providing snacks and drinks, as well as the Institute of Mathematics for financial support.

On Saturday, July 2, 2022, the Long Night of the Sciences will take place in Berlin. There will be two program points in the Mathematics Library:

• 17-22 h: Art exhibition Embroidery : Density and Transparency

The exhibition features the works of the Berlin-based Chilean fiber artist Javiera González Zarzar, who is currently a doctoral student in architecture at TU Berlin.

In her works, embroidery acquires an abstract dimension where the exhibition of the inherent qualities of the materials predominates. Her embroideries have a spatial quality, either by their size or how color is employed. In her works, the gradation of the wool’s color and the superimposition of semi-transparent meshes create the illusion of depth.

• 19-20 h: Panel Discussion On Textiles and Architecture

Javiera González Zarzar discusses with three guests the different aspects of textiles in the context of architecture, art and mathematics. Invited to the discussion are textile scientist and museum director Rouven Lotz and mathematicians Henriette Lipschütz and Ulrich Reitebuch, who do research in the Mathematical Geometry Processing group at Freie Universität Berlin. The event will be held in English.

Tickets for the Long Night of the Sciences can be purchased herehttps://www.langenachtderwissenschaften.de/en/.

Last year, a good 600 mathematics "preprints" from 1996 - 2020 were moved to the TU Berlin open access repository DepositOnce. The Institute of Mathematics' preprint series was discontinued at the end of 2020, so a new, long-term archive was needed for the articles that had appeared up to that point. The completed data migration ensures for the future that the many articles published in the series by the mathematicians of the Technische Universität Berlin will remain accessible. A brief overview of the project can be found on the University Library's blog "Publishing at the TU Berlin".

All mathematics preprints available in the repository can be found here.

As of today, FFP2 masks are once again mandatory for all time spent in the library, including while working at the desk. Our reading rooms are intended to be available for everyone, also to those who are particularly at risk, so thoughtfulness is important to us. We want to provide a high level of protection for everyone, because you can only learn productively if you feel safe.

This arrangement also allows us to offer more seats again. As of now, our group study rooms Banach, Hilbert, Sobolev and Krylov on the balcony are available again.

3G proof is no longer required to visit the libraries. Nevertheless, we ask everyone to remain responsible and cautious, and to stay at home in case of symptoms and suspicion of infection with the Corona virus.

Currently, books and T-shirts of the former research center MATHEON are available for purchase in our Mathematics Library for a donation of 2,-€ per piece. From the "Matheon" the Berlin Mathematics Research Center MATH+ has emerged in 2019. Part of it is also the Berlin Mathematical School.
