Talk Title : Goldbach’s Conjecture and the Riemann Hypothesis in Number Theory, and Their Relations to Zeta Functions

Abstract: Number Theory has a very long history that dates back to thousands of years ago. The main goal of this study is to understand properties of numbers which can essentially be reduced to understanding prime numbers. Number Theory has evolved over time and yet we are still left with several important old problems. Among, Goldbach’s conjecture which is celebrating its 280th anniversary this year (by the time of my talk in 2022) and the Riemann hypothesis which is now over 160 years old remain unsolved. In this talk, I would like to explain what these problems are about and briefly introduce a few recent works which are related to them, especially how the distribution of zeros of the Riemann zeta function comes into play. My talk will be given in the perspective of Analytic Number Theory.

Abstract: Part II Diversity Panel Discussion 4-5 pm

Seminar talk on the James Webb Space Telescope mission by Dr. H. Philip Stahl, Space Optics Manufacturing Technology Center, NASA Marshall Space Flight Center , AL 35812

Organized by the OIST Optics and Photonics Student Society

C-Hub warmly invites you to join us to hear about best practices for ensuring your teaching is engaging, transformative, and impactful.

Dr. Jason Heustis will articulate the essentials for creating a great course and discuss how to build a syllabus that will create clear, intentional pathways for teaching and learning. We will also discuss how “active learning” facilitates deep understanding and engages students from diverse backgrounds. Participants will also have the opportunity to consider different modes of assessment to measure student learning and mastery, and be strategic in development the assessments that will be aligned with your desired learning objectives.

Mr. Julian Weigt , Aalto University Title: Higher dimensional techniques for the regularity of maximal functions Abstract:

It has been an open question if maximal operators M satisfy the endpoint regularity bound \(mathop{\mathrm{var}}(Mf) \leq C \mathop{\mathrm{var}}(f)\). So far the majority of the known results has been in one dimension. I give an overview of the progress on this question with a focus on the techniques. Next I present the techniques used in the recent proofs of \(mathop{\mathrm{var}}(Mf) \leq C \mathop{\mathrm{var}}(f)\) for several maximal operators in higher dimensions. They are mostly geometric measure theoretic in the spirit of the relative isoperimetric inequality and involve a stopping time and various covering arguments.

Dr. David Beltran, University of Wisconsin – Madison Title: Endpoint Sobolev regularity of the fractional maximal function Abstract: Abstract: I will report some of the recent progress regarding the boundedness and continuity of the map \(f \mapsto |\nabla M_\beta f|\) from the endpoint space \(W^{1,1}(\mathbb{R}^d)\) to \(L^{d/(d-\beta)}(\mathbb{R}^d)\), where \($M_\beta\) denotes the fractional version of either the centered or uncentered Hardy--Littlewood maximal function. After contributions by several authors, the problem is now totally solved in an affirmative way. I will focus on my contributions, which correspond to the radial case (in joint work with J. Madrid), and also to the general case for the continuity of the map (in joint work with C. González-Riquelme, J. Madrid and J. Weigt).

Title: Helgason-Fourier analysis techniques on hyperbolic spaces and sharp geometric and functional inequalities Speaker : Professor Guozhen Lu, University of Connecticut Abstract : In this talk, we will report some recent progress on sharp geometric and functional inequalities by using the Helgason-Fourier analysis techniques on hyperbolic and symmetric spaces. These techniques allow us to establish sharp higher order Hardy-Sobolev-Maz'ya and Hardy-Adams inequalities on upper half spaces, complex Siegel domains and quaternionic and octanionic hyperbolic spaces. Some applications to PDEs will also be given. Click here to register.

Living electronics and fate of plastics

Organic electronics is a rising field, with novel applications including but not limited to stretchable solar cells, flexible display screens, and biosensors. The high performance of these organic electronics is enabled by the outstanding optoelectronic and thermomechanical features of organic semiconducting materials. As the field has progressed, bioelectronics has attracted increasing interest. Bioelectronics, merging manufactured electronics and biology, has emerged as a promising platform for translating electronic signals into ionic ones and vice versa , converting ionic signals into electronic signals ( e. g., biosensors and ionic skins). As a result, in recent years, applications in tissue engineering, drug delivery, electrophoresis and physiology have been developed. As we look into the future of bioelectronics, “living” electronics that merge the synthetic and biological world, holds some interest.

Separate to the above, microplastics composed of various plastic and polymeric materials pose as a major global environmental issue that can cause detrimental consequences to marine organisms and across the food chain. We have been collaborating with researchers at UW to identify microplastics in marine organisms in the Puget Sound and have identified that not all organisms consume the same microplastics.

In both projects, we seek to initiate collaborations with those at OIST and look forward to initiating discussions with various units.

★DISTINGUISHED LECTURE Professor Yoshikazu Giga , The University of Tokyo Title: On a singular limit of a single-well Modica-Mortola functional and its applications Abstract:

It is important to describe the motion of phase boundaries by macroscopic energy in the process of phase transitions. Typical energy describing the phenomena is the van der Waals energy, which is also called a Modica-Mortola functional with a double-well potential or the Allen-Cahn functional. It turns out that it is also important to consider the Modica-Mortola functional with a single-well potential since it is often used in various settings including the Kobayashi-Warren-Carter energy, which is popular in materials science. It is very fundamental to understand the singular limit of such a type of energies as the thickness parameter of a diffuse interface tends to zero. In the case of double-well potentials, such a problem is well-studied and it is formulated, for example, as the Gamma limit under L 1

convergence.

However, if one considers the Modica-Mortola functional, it turns out that L 1

convergence is too rough even in the one-dimensional problem.

We characterize the Gamma limit of a single-well Modica-Mortola functional under the topology which is finer than L 1

topology. In a one-dimensional case, we take the graph convergence. In higher-dimensional cases, it is more involved. As an application, we give an explicit representation of a singular limit of the Kobayashi-Warren-Carter energy. Since the higher-dimensional cases can be reduced to the one-dimensional case by a slicing argument, studying the one-dimensional case is very fundamental. A key idea to study the one-dimensional case is to introduce “an unfolding of a function” by changing an independent variable by the arc-length parameter of its graph. This is based on a joint work with Jun Okamoto (The University of Tokyo), Masaaki Uesaka (The University of Tokyo, Arithmer Inc.), and Koya Sakakibara (Okayama University of Science, RIKEN).
