Events

The main topics will touch interactions between Topological Group Theory and Lie Theory. The format is designed for a restricted number of postgraduate students and academics, who work in Topological Group Theory and Lie Theory.

This is a pluridisciplinary school on modeling. Minicourses will be given by Italo Capuzzo Dolcetta [mathematical analysis], Jean-Michel Coron [mathematical analysis], Francesco dell’Isola [mechanics], Antoine Falaize [scientific computing], Jean-Louis Giavitto [computer sciences] and Thierry Paul [mathematical physics].

Since October 2020 the monthly online Mathematical Relativity colloquium takes place on zoom every first Thursday of each month at 3:30 pm CET/CEST, except January and in the summer. The colloquium is meant to be accessible to and informative for mathematicians and mathematical physicists with a background in General Relativity, widely interpreted to include Lorentzian Geometry, and Geometric Analysis of various Partial Differential Equations related to General Relativity. It is aimed to present motivation and applications of particular results and / or introduce specific subfields, while refraining from too much technicalities. Next speaker on 2 November 2023: Gehard Huisken (University of Tübingen) - Some observations on quasi-local mass and quasi-local radius For more details, the zoom access and subscription to the announcements see the webpage jomarec.org.

Cracking the neural code is one of the longstanding questions in neuroscience. How does the activity of populations of neurons represent stimuli and perform neural computations? Decades of theoretical and experimental work have provided valuable clues about the principles of neural coding, as well as descriptive understandings of various neural codes. This raises a number of mathematical questions touching on algebra, combinatorics, probability, and geometry. This workshop will explore questions that arise from sensory perception and processing in olfactory, auditory, and visual coding, as well as properties of place field codes and grid cell codes, mechanisms for decoding population activity, and the role of noise and correlations. These questions may be tackled with techniques from information theory, mathematical coding theory, combinatorial commutative algebra, hyperplane arrangements, oriented matroids, convex geometry, statistical mechanics, and more.

The workshop aims to present and discuss recent developments in the field of quaternions and octonions by bringing together scientists from both pure and applied mathematics, physics, scientific computing, engineering, and other applied sciences. There will be 4 invited lectures by Alessandro Perotti (University of Trento, Italy), with the talk: "An alternative Fueter Theorem on octonions and Clifford algebras" Aleš Ude (Jožef Stefan Institute, Slovenia), with the talk: "Application of quaternions in robot learning and control" João Pimentel Nunes (Instituto Superior Técnico, Portugal), with the talk: "Coherent state transforms and Clifford analysis" José María Pérez Izquierdo (University of La Rioja, Spain), with the talk: "Some attitude estimation techniques with quaternions" and accepted short communications. As there might be participants who cannot attend NTQO 2023 in person, the event will be held in a hybrid format.

The Aim of the Spring School is to bring together researchers and students working in Lie symmetry and related methods applications in differential and difference equations. Topics include but not limited to invariant solutions, optimal systems, Noether symmetries and conservation laws. Recent development in the area will provide the opportunities for future directions of research via active collaboration and discussion.

In this conference, we will celebrate the 60th birthdays of Helena J. Nussenzveig Lopes and Milton C. Lopes Filho focusing on the major contributions of their work in the field of mathematical modeling and rigorous analysis of fluid dynamics problems, particularly incompressible flows with little regularity (non-smooth) and turbulent flows. The program will consist of invited and contributed lectures and a poster session.

This workshop will bring together leading researchers at the interfaces of topology, geometry and neuroscience to take stock of recent work and outline future directions. This includes a focus on topological data analysis (persistent homology and related methods), topological analysis of neural networks and their dynamics, topological decoding of neural activity, evolving topology of dynamic networks (e.g., networks that are changing as a result of learning), and analysis of connectome data. Related topics may include the geometry and topology of deep learning, as well as low-dimensional projections of trained networks.

The WIAF conference highlights recent, excellent developments on automorphic forms in all aspects. It is specially, but not exclusively, addressed to female mathematicians. Registration is without a free but mandatory. Plenary speakers: Paloma Bengoechea (U Barcelona), Annika Burmester (U Hamburg), Claire Burrin (U Zürich), Anne-Maria Ernvall-Hytönen (U Helsinki), Özlem Imamoglu (ETH Zürich), Katharina Jochemko (KTH Stockholm), Maryna Viazovska (EPFL; TBC), Marie-France Vigneras (IMJ-PRG Paris), Katrin Wendland (U Dublin) Organizers: Claudia Alfes-Neumann (U Bielefeld), Anna von Pippich (U Konstanz), Anke Pohl (U Bremen)

This is a hands‐on workshop and will introduce delegates to the freely available, open‐source and general‐purpose programming language Python ‐ which is one of the most popular programming languages in the world. Python will be used to enhance the teaching and learning of Mathematics at A‐Level and beyond. Delegates need no prior knowledge of programming to benefit from this workshop.
