OIST and Keio University, Japan's very first private institution of higher learning located in the center of Tokyo, are starting a series of short seminars (OIST-KEIO SHOWCASE TALK) to introduce each other's researchers to promote future collaboration.

Prof. Dr. Julijana Gjorgjieva

Assistant Professor in Computational Neuroscience, Max Planck Institute for Brain Research, Technical University of Munich

The emergence of organization and computation in neural circuits

How neural circuits become organized during early postnatal development based on patterns of spontaneous activity and different plasticity mechanisms. Prof. Julijana will show the emergence of organization at the sub-cellular and cellular level and discuss implications for computations implemented by these networks. These theoretical models and simulations are supported by experimental data and make numerous predictions for future experiments.

Quantum-enabled operation of a microwave-optical interface - Prof. Johannes M. Fink, Institute of Science and Technology Austria

Next week, at 2pm JST on Wednesday 27th October in Lab 4 Seminar Room E48 , OIST's own Yasha Neiman will tell us about " A microscopic derivation of the quantum measurement postulates".

The 27th East Asia Joint Symposium

~Reboot 2021: Explorling Life Science in the Post-Pandemic Era~

Professor Oscar Domingues Bonilla , The University of Lyon Title: John–Nirenberg spaces revisited Abstract:

We study John—Nirenberg-type spaces where oscillations of functions are controlled via covering lemmas. Our methods give new surprising results and clarify classical inequalities. Joint work with Mario Milman (Florida and Buenos Aires).

The colloquium will be held once a month. It will be held online for the time being. Each event consists of a one-hour talk on mathematics followed by a one-hour diversity panel discussion session.

In the mathematics part, we will hear an exciting overview talk for a general audience. October speaker is Megumi Harada, Professor of McMaster University. In the discussion session, we will hear about the speaker's personal journey as a mathematician. You can take inspiration from them and exchange ideas with other participants in a small group. After the sessions are over, there will be a tea time where participants can chat freely.

You can join Part I only or both parts of the colloquium. Please register before Oct 18th, 5 pm. Click here to register!

Title: Quasiconformal and Sobolev mappings in metric measure spaces

Speaker: Panu Lahti, Chinese Academy of Sciences

Abstract: Starting from Gehring, the equivalence between the metric, geometric, and analytic def- initions of quasiconformality has been investigated by various authors. There are many results stating that if a mapping is metrically quasiconformal, perhaps only in a relaxed sense, then it is analytically quasiconformal, or at least a Sobolev mapping. In recent joint work with Xiaodan Zhou, we have shown an improved version of such a result, which seems to detect more Sobolev mappings than previous results in the literature. I will discuss these results as well as the general strategy of the proofs.

Seminar hosted by QG Unit. Speaker: Karapet Mkrtchyan, Imperial College London Title: Duality-symmetric formulation of electrodynamics and (chiral) p-form generalizations

Speaker: Paul Wedrich , University of Hamburg Title: Knots and quivers, HOMFLYPT and DT

Professor Alex Iosevich, University of Rochester Title: Finite point configurations and the Vapnik-Chervonenkis dimension Abstract:

The Vapnik-Chervonenkis (VC) dimension was invented in 1970 to study learning models. This notion has since become one of the cornerstones of modern data science. This beautiful idea has also found applications in other areas of mathematics. In this talk we are going to describe how the study of the VC-dimension in the context of families of indicator functions of spheres centered at points in sets of a given Hausdorff dimension (or in sets of a given size inside vector spaces over finite fields) gives rise to interesting, and in some sense extremal, point configurations.

FALL 2021 Nonlinear Analysis Online Seminar Seminar Series Sagun Chanillo , Rutgers University Title: Local Version of Courant's Nodal domain theorem. Abstract:

Consider a smooth, compact Riemannian manifold with no boundary, endowed with a smooth metric. A famous theorem of Courant states that the k-th eigenfunction for the Laplace-Beltrami operator can have at most k nodal domains. Nodal domains are the open and connected sets where the eigenfunction does not vanish. H. Donnelly and Fefferman obtained some 30 years ago a local version of this theorem. Improvements were made by Chanillo-Muckenhoupt and others. In this talk we obtain the optimal local version of the local Courant theorem. We also relate this result to conjectures of S.-T. Yau on nodal sets, that is the zero set of eigenfunctions. The results of our talk have been obtained jointly with A. Logunov, E. Mallinikova and D. Mangoubi.
