Dear Members of the SIAM Chapter at Uni Potsdam,
on March 29th, we will elect a new set of SIAM-officers (President, Vice-President, Treasurer, Secretary). If you are intereset in joining the organizational side of the chapter or would like some more information on what duties each role entails, please write an email to one of the officers and we will answer your questions. There will also be an introduction of the SIAM chapter and roles on the day of the election.
Please note that only members of the chapter will be able to vote - join us by subscribing to our mailing list!
Get to know what your fellow Ph.D students are working on!
Time: 22.02.23 at 4:00 pm
Place: house 9, room 2.22. Details are announced via mailing list "SIAM-chapter-list", or ask Franziska or Florian.
Speaker: Matthias Himmelmann
Topic: Framework Materials and Cylinder Packings
Abstract: In a geometric context, framework materials are structures composed of many rigid bars (or edges), pinned together at vertices where the bars can freely rotate relative to each other. These structures can be rigid or deformable, depending on the way in which the bars are joined together. Possible deformation pathways of a framework structure can be described in an algebraic context, with each rigid rod represented by polynomial constraints. We use this theoretical concept to robustly model (curvilinear) cylinder packings and their dynamical properties by considering Riemannian Optimization and the mathematical theory of filaments in tight contact.
We invite all Bachelor, Master and PhD Students to join us!

Topic: Frequentist Ensemble Kalman Filtering
Abstract: In this talk I will briefly discuss statistical inverse problems, and how we can solve them using the Ensemble Kalman filter. I will then explain how in this setting, we implement early stopping in the statistical sense, and give an introduction into the two toy models we use to develop the theory. I will hopefully end with an overview of the numerical simulations that empirically lead us into the theory.
We are happy to invite you to our next SIAM social event next Wednesday, 30th of November at 4pm. We are joining forces with the SFB1294 - Data Assimilation to make the best Christmas cookies this SIAM chapter has ever seen! We meet in the Lesecafé, ground floor of house 14.
We will provide Cookie dough and utensils as well as some decorations and drinks. You are welcome to also bring some cookie cutters, other utensils for decorating, sprinkles. More drinks can be purchased in the Lesecafé or you can bring your own.

We are happy to see you on Wednesday!

Topic: Higher Order Laplacians on Simplicial Complexes
Abstract: As higher dimensional analogues of graphs, simplicial complexes appear in many areas of mathematics such as topology, combinatorics, data analysis and number theory. However, it is still somewhat a mystery what information about the geometry is encoded in the spectra of its Laplace Operators such as the Hodge Laplacian. In this talk we will define Laplacians for infinite weighted simplicial complexes, discuss basic properties like boundedness and essential self-adjointness and draw parallels to magnetic Schrödinger operators on graphs.
We are happy to invite you to our next SIAM social event next Wednesday, 27th of June at 4pm. Like last time, we will meet at the ping-pong tables behind house 11. In case of rain, we will meet in the coffee room in house 9 (room 2.09.2.10).

We hope to see you at the seminar!
We are happy to announce that we founded a SIAM Student Chapter in Potsdam in February 2021. See here for general information about SIAM student chapters.
The Student Chapter is an association of students at the University of Potsdam.
What are the benefits of being organised as a SIAM Student Chapter?
Who can become a member?
How to become a member?
General information:
If you have any questions feel free to ask the PhD representatives Florian and Franzi. The faculty advisor of this Chapter is Prof. Dr. Melina Freitag.
Can you summarize the content of your research in 3 minutes? Can you do it in an entertaining way? Then our SIAM Slam might be for you!
As a joint initiative of our SIAM Chapter and the SIAM Chapters of Aachen, Heidelberg and Magdeburg, we would like to invite you to SIAM Slam. There, different participants will present their theses or other scientific findings in a very short amount of time. The audience will choose the most entertaining and informative presentation.
The event will take place via zoom on the 10th of June at 18:00. Feel free to ask Florian for the login data.
Each participant will have exactly 3 minutes for their presentation. A slideshow is allowed, however, we advise reducing the number of slides. There will be a prize for the best presentation.
If you just want to be a spectator, you are welcome to join as well. Then, no registration is needed. In the second part of the event, we will run a short quiz based on the presentations. Here, the winner will also get a small prize. We plan to close the event with an opportunity to together play games online.
If you always wanted to try your hand at being a science communicator, this is your time. Who knows, maybe you are the next Richard Feynman or Stephen Hawking? :)
