Title : The Obstruction of Orientability of Real Monopole Floer Homology Abstract : The Real Seiberg-Witten theory is one of a stong tool in knot theory and surface knot theory. For example, that can detect exotic P^2-knot and Kang-Park-Taniguchi proved that any non trivial cable of figure eight knot is not slice using Real Seiberg-Witten theory. This theory is also provide interesting phenomena in index theory, since Real Seiberg-Witten theory can be seen as a "non-linear version" of Atiya's Real K-theory. For example, there is an obstruction to orient moduli space of Real Seiberg-Witten eqations on closed 4-manifolds. Recently, Bonciocat obtained a obstruction to lift the real Heegaard Floer homology from mod 2 coefficient to Z-coefficient. In this talk, we give a canonical way to obtain Z- coefficient real monopole Floer homology of double branced cover of a link in homology S^3 in the case when the obstruction vanishes. We also proved that the Bonciocat's obstruction is also obstract Z-coefficient in real monopole, however the proof is different. This is joint work with Jiakai Li.

This seminar is for graduate students considering academic careers abroad after obtaining their Ph.D. We invite a speaker active in international academia to share what a global career path can look like. You will learn how early-career scientists can best prepare for success in a career. This yearʼs speaker is Dr. Nadia Rabehi , who earned her Ph.D. in energy materials and surface sciences at OIST, and is now a postdoctoral researcher at IM2NP (Institute of Materials, Microelectronics and Nanoscience of Provence). Her current research focuses on defects and deformation in crystalline silicon ingots used for photovoltaic applications, with the aim of improving industrial production processes. Dr. Nadia Rabehi will talk about how she applied for positions in Europe, the selection process, the academic job market, and work-life balance in European Academia.

Title : 2-torsion in Instanton Homology Abstract : This talk will focus on the presence of 2-torsion in a specific flavour of instanton (knot) homology introduced by Kronheimer--Mrowka. The main results are that the Poincaré homology sphere and fibered knots in 3-manifolds exhibit 2-torsion in their instanton homology. The key gauge theoretic input used in both results is a new surgery exact triangle, which relates instanton homology of three manifolds obtained by surgeries on a knot to singular instanton homology of the knot. Time permitting, we also sketch the use of sutured Floer theory in the second main result. Part of the talk is based on joint work with Zhenkun Li and Fan Ye.

Title : Signs in real monopole Floer homology

Abstract :

The computation of the 3-dimensional framed real Seiberg–Witten invariant of the branched double cover of a knot K is instrumental in Miyazawa's construction of exotic P^2-knots. This invariant, known as Miyazawa's degree invariant deg(K), is the Euler characteristic χ(HMR) of framed real monopole Floer homology (HMR). A priori deg(K) is defined only up to an overall sign, since the real Dirac operator has no complex orientation. Worse, signs associated to distinct real spin^c structures are not comparable. Resolving the latter issue is essential for developing computational techniques for real Seiberg--WItten invariants.

I will explain how to fix the sign of the 3-dimensional count, in other words, define an absolute mod-two grading, via a mod-two index-theoretic correction term. This yields a total Euler characteristic \tilde{χ} that sums over all real spin^c structures, the analogue of \hat{χ} in real Heegaard Floer homology (HFR). Recent work of Srivastava provides the motivating results: an absolute mod-two grading in \hat{HFR} and the evaluation of \hat{χ} in terms of the Alexander polynomial at \sqrt{-1}. This is joint work with Ciprian Manolescu.

Title : Peg problems and symplectic geometry.

Abstract : The unsolved Toeplitz Square Peg Problem was posed in 1911. It asks whether all Jordan curves (subsets of the real plane homeomorphic to a circle) contain four points at the vertices of a square. We shall discuss this problem and related "peg" problems. They sometimes admit a description in terms of symplectic geometry. No prior knowledge of pegs or of symplectic geometry assumed. (Joint work with Josh Greene).

Title: 数も式もない計算

概要：

人——プロの数学者も含めて——は「計算」というと数や式の操作を連想しがちです。

We are now accepting applications from healthcare and deep-tech startups for the OIST-Lifetime Pitch Elevate 2026, a VC-mentored pitch competition for idea-stage to seed/early-stage startups. The competition will take place as part of the OIST-Lifetime Startup Elevate 2026 on November 4 and 6 at OIST.

As this is a highly competitive pitch competition, not all applicants will be selected. However, if you are a local startup based in Okinawa or a spin-out from PARKS, you may still have the opportunity to present at a dedicated local startup pitch event held alongside the main program.

We encourage all eligible local startups to apply and look forward to receiving your applications.
