Arthur Ogus (University of California, Berkeley)
Introduction to Logarithmic Geometry III (ENGLISH)
[ Abstract ]
Logarithmic Geometry was invented (or discovered) in the 1980's, with crucial ideas contributed by Deligne, Faltings, Fontaine, Illusie, and especially K. Kato. It provides a systematic framework for the study of the related phenomena of compactification and degeneration in algebraic and arithmetic geometry, with applications to number theory. I will attempt to explain the main ideas and foundations of Kato's version of log geometry, with an emphasis on its geometric and topological aspects.

Convexity preserving properties for nonlinear evolution equations (English)

Convexity preserving properties for nonlinear evolution equations (English)
[ Abstract ]
It is well known that convexity of solutions to a general class of nonlinear parabolic equations in the Euclidean space is preserved as time develops. In this talk, we first revisit this property for the normalized infinity Laplace equation and the curvature flow equation by introducing an alternative approach based on discrete game theory. We then extend our discussion to Hamilton-Jacobi equations in the Heisenberg group and in more general geodesic metric spaces.

Cohomology of the moduli space of graphs and groups of homology cobordisms of surfaces (JAPANESE)
Takuya Sakasai (The University of Tokyo)
Cohomology of the moduli space of graphs and groups of homology cobordisms of surfaces (JAPANESE)
[ Abstract ]
We construct an abelian quotient of the symplectic derivation Lie algebra of the free Lie algebra generated by the fundamental representation of the symplectic group. It gives an alternative proof of the fact first shown by Bartholdi that the top rational homology group of the moduli space of metric graphs of rank 7 is one dimensional. As an application, we construct a non-trivial abelian quotient of the homology cobordism group of a surface of positive genus. This talk is based on joint works with Shigeyuki Morita, Masaaki Suzuki and Gwénaël Massuyeau.

Yohei Kashima (Graduate School of Mathematical Scineces, The University of Tokyo)
Superconducting phase in the BCS model with imaginary
magnetic field (JAPANESE)
[ Abstract ]
We prove that in the BCS model with an imaginary magnetic field
at positive temperature a spontaneous symmetry breaking (SSB) and
an off-diagonal long range order (ODLRO) occur. Here the BCS model
is meant to be a self-adjoint operator on the Fermionic Fock space,
consisting of a free part describing the electrons' nearest neighbor
hopping and a quartic interacting part describing a long range
interaction between Cooper pairs. The interaction with the imaginary
magnetic field is given by the z-component of the spin operator
multiplied by a pure imaginary parameter. The SSB and the ODLRO are
shown in the infinite-volume limit of the thermal average over the
full Fermionic Fock space. The insertion of the imaginary magnetic
field changes the gap equation. Consequently the SSB and the ODLRO
are shown in high temperature, weak coupling regimes where these
phenomena do not take place in the conventional BCS model. The proof
is based on the method of Grassmann integration.

Second mod 2 homology of Artin groups (JAPANESE)
[ Abstract ]
After a brief survey on the K($\pi$,1) conjecture and homology of Artin groups, I will introduce our recent result: we determined second mod 2 homology of arbitrary Artin groups without assuming the K($\pi$,1)-conjecture. The key ingredients are Hopf's formula and a result of Howlett on Schur multipliers of Coxeter groups. This is a joint work with Ye Liu.

Kenta Hashizume (Department of Mathematics, Kyoto University)
Minimal model theory for relatively trivial log canonical pairs
[ Abstract ]
The good minimal model conjecture is an important open problem in the birational geometry, and inductive arguments on the dimension of varieties are useful when we work on this conjecture. In fibration with a log canoinical pair having some good properties, it is expected that the above conjecture for the log canonical pair on total space can be proved by investigating the general fiber and base variety of the fibration. In this talk, I will explain an inductive argument in fibrations with relatively trivial log canonical pairs and introduce some applications of the inductive argument.

Direct summand conjecture and perfectoid Abhyankar lemma: an overview (English)
[ Abstract ]
According to Hochster's direct summand conjecture (1973), a regular ring R is a direct summand, as an R-module, of every finite extension ring. We shall outline our recent proof which relies on perfectoid techniques. Similar arguments also establish the existence of big Cohen-Macaulay algebras for complete local domains of mixed characteristics.

Takahiro Oba (Tokyo Institute of Technology)
Higher-dimensional contact manifolds with infinitely many Stein fillings (JAPANESE)
[ Abstract ]
A Stein fillings of a given contact manifold is a Stein domain whose boundary is contactomorphic to the given contact manifold.
Open books, Lefschetz fibrations, and mapping class groups of their fibers in particular help us to produce various contact manifolds and their Stein fillings. However, little is known about mapping class groups of higher-dimensional manifolds. This is one of the reasons that it was unknown whether there is a contact manifold of dimension > 3 with infinitely many Stein fillings. In this talk, I will choose a certain symplectic manifold as fibers of open books and Lefschetz fibrations and by using them, construct an infinite family of higher-dimensional contact manifolds with infinitely many Stein fillings.

Yuta Koike (Tokyo Metropolitan University, JST CREST)
Wavelet-based methods for high-frequency lead-lag analysis
[ Abstract ]
We propose a novel framework to investigate the lead-lag effect between two financial assets. Our framework bridges a gap between continuous-time modeling based on Brownian motion and the existing wavelet methods for lead-lag analysis based on discrete-time models and enables us to analyze the multi-scale structure of lead-lag effects. We also present a statistical methodology for the scale-by-scale analysis of lead-lag effects in the proposed framework and develop an asymptotic theory applicable to a situation including stochastic volatilities and irregular sampling. Finally, we report several numerical experiments to demonstrate how our framework works in practice. This talk is based on a joint work of Prof. Takaki Hayashi (Keio University).
