Title: P-Dirichlet spaces and the resolution of the resistance and energy image density conjectures

Abstract: I will describe the resolution of two conjectures related to Dirichlet forms. In both cases a conceptually simple solution arises by stepping away from the p=2 regime. This leads to a new definition of a p-Dirichlet space, which unifies three quite different areas: Dirichlet form theory, Analysis on fractals and Analysis on metric spaces. The talk includes joint work with Mathav Murugan

Speaker: Aleksis Koski, Aalto University

Title:The Trace Theorem for Sobolev Homeomorphisms

Abstract: Classical Sobolev trace theory tells us when a boundary map can be extended as a Sobolev function inside a given domain in R^n. For the purposes of minimization problems in Nonlinear Elasticity, it is natural to rephrase this question in the context of extending a given embedding of the boundary as a homeomorphic Sobolev map. In this talk, I will explain what is known about this problem, ending with a full trace theory for Sobolev homeomorphisms in 2D.

OIST-Keio Showcase Talk Series Vol. 9 – Proteins in Focus: Cryo-EM and Structural Frontiers

The ninth edition of the OIST-Keio Showcase Talk Series brings together experts from Keio University, The University of Osaka’s Institute for Protein Research, and OIST to explore cutting-edge advances in protein science and cryo-electron microscopy. Talks will cover drug design, photosynthetic complexes, molecular motors, enzyme evolution, and viral architectures. This symposium highlights how cryo-EM is transforming our understanding of molecular mechanisms and driving innovation in medicine, biotechnology, and environmental science - with the aim of connecting researchers across institutions to enable interdisciplinary innovation.

This symposium will be followed by the 2026 Cryo-Electron Microscopy Course from January 28 to 30, which is aimed at beginners (admission is free). There experienced researchers will provide an overview of the current state-of-the-art and share their experiences in demonstrations and hands-on practice.

Title: Design of Deployable Structures Based on Geometry and Biomimetics

Abstract This research investigates deployable structures that can be compactly folded for transportation and storage and expanded to form spatial configurations. To address challenges such as material interference due to thickness, fabrication complexity, and construction safety, three fundamental operations—folding, cutting, and weaving—are identified and systematically applied as design strategies. Drawing on biomimetic principles inspired by insect hindwings and fungal net-like structures, the study develops geometry-based design models for each operation. By integrating geometry, biomimetics, and deployable design, this research demonstrates new possibilities for architectural deployable structures.

発表タイトル： 幾何学および生物模倣に基づく展開構造物の設計

要旨： 本研究は、運搬・収納時に小さく折りたたみ、展開によって空間を構成する展開構造物を対象とする。部材厚みによる干渉や施工の複雑性といった課題に対し、「折る」「切る」「編む」という三つの形態操作を整理し、それぞれに対応した設計手法を提案した。さらに、ハサミムシ後翅やキヌガサタケ菌網などの生物構造を模倣し、幾何学的条件に基づく設計モデルを構築した。これにより、展開構造物の新たな設計可能性を示す。

BiTS Japan is a 15-week, part-time training program to instill knowledge of how to define BIG problems that face mankind, identify the metrics that, if achieved, could catalyze serious change and how to manage the cooperative research program to solve the problem. The training program was developed based on vast experience of the developers as they executed more than $1B of research programs. Join Dr. Douglas Wicks, Strategic Director of BiTS Japan, as he previews the training program and invites OIST faculty, researchers, students, and entrepreneurs to participate!

Speaker:Julius Lohmann JSPS International Research Fellow, Institute of Science Tokyo Title: Dynamic inverse problems regularized with Wasserstein-1 transport Julius Lohmann JSPS International Research Fellow, Institute of Science Tokyo

Abstract: The (classical, balanced) Wasserstein-p distance can be used as a measure of how close a source and sink mass distribution (with equal mass) are. In recent years, the Wasserstein-2 distance has been employed in the temporal regularization of dynamic inverse problems. The so-called Benamou–Brenier formula states that it can be written as the square root of the performed physical work through the transport from the source to the sink. In my talk, I will instead focus on dynamic inverse problems regularized with Wasserstein-1 transport. The Wasserstein-1 distance can be interpreted as the optimal transport cost with respect to the Euclidean distance: it equals infπ R |x−y|dπ(x, y), where measure element dπ(x, y) indicates the (infinitesimal) amount of mass moving from location x to y. I will explain a novel dynamic inverse problem on time-parameterized curves in the induced Wasserstein-1 (metric) space. It is a natural extension of static sparse optimization problems such as lasso or TV regularization. One essential difference to classical regularization with Wasserstein-2 transport is that it allows for discontinuous decision variables (realized as BV curves). Despite this weak regularity requirement and the non-differentiability of the cost function (x, y) 7→ |x − y|, it is possible to prove the existence of a sparse solution and its characterization. I will present this result. Further, I will detail an adaption of the fully-corrective generalized conditional gradient method to the problem and highlight a natural discretization approach. Finally, I will show some numerical examples. Joint work with: Marcello Carioni
