Testing log K-stability by blowing up formalism
Yuji Odaka, Song Sun
We study logarithmic K-stability for pairs by extending the formula for Donaldson-Futaki invariants to log setting. We also provide algebro-geometric counterparts of recent results…
Open Book Foliations
Tetsuya Ito, Keiko Kawamuro
We study open book foliations on surfaces in 3-manifolds, and give applications to contact geometry of dimension 3. We prove a braid-theoretic formula of the self-linking number of…
Is an irng singly generated as an ideal?
Nicolas Monod, Narutaka Ozawa, Andreas Thom
Recall that a rng is a ring which is possibly non-unital. In this note, we address the problem whether every finitely generated idempotent rng (abbreviated as irng) is singly gener…
On the colored Jones polynomials of ribbon links, boundary links and Brunnian links
Sakie Suzuki
Habiro gave principal ideals of Z[q,q^{-1}] in which certain linear combinations of the colored Jones polynomials of algebraically-split links take values. The author proved that t…
On the universal sl_2 invariant of Brunnian bottom tangles
Sakie Suzuki
A link L is called Brunnian if every proper sublink of L is trivial. Similarly, a bottom tangle T is called Brunnian if every proper subtangle of T is trivial. In this paper, we gi…
Towards a state minimizing the output entropy of a tensor product of random quantum channels
Benoit Collins, Motohisa Fukuda, Ion Nechita
We consider the image of some classes of bipartite quantum states under a tensor product of random quantum channels. Depending on natural assumptions that we make on the states, th…
Biadjointness in cyclic Khovanov-Lauda-Rouquier Algebras
Masaki Kashiwara
We prove that the simple root functors E and F appearing in the categorification of irreducible highest weight modules of quantum groups via cyclotomic Khovanov-Lauda-Rouquier alge…
Periodic body-and-bar frameworks
Ciprian S. Borcea, Ileana Streinu, Shin-ichi Tanigawa
Abstractions of crystalline materials known as periodic body-and-bar frameworks are made of rigid bodies connected by fixed-length bars and subject to the action of a group of tran…
Strichartz estimates for Schrödinger equations with variable coefficients and potentials at most linear at spatial infinity
Haruya Mizutani
In the present paper we consider Schrödinger equations with variable coefficients and potentials, where the principal part is a long-range perturbation of the flat Laplacian and po…
Rooted-tree Decompositions with Matroid Constraints and the Infinitesimal Rigidity of Frameworks with Boundaries
Naoki Katoh, Shin-ichi Tanigawa
As an extension of a classical tree-partition problem, we consider decompositions of graphs into edge-disjoint (rooted-)trees with an additional matroid constraint. Specifically, s…
Metric spaces with subexponential asymptotic dimension growth
Narutaka Ozawa
We prove that a metric space with subexponential asymptotic dimension growth has Yu's property A.
Homology cylinders of higher-order
Takahiro Kitayama
We study algebraic structures of certain submonoids of the monoid of homology cylinders over a surface and the homology cobordism groups, using Reidemeister torsion with non-commut…
Log-canonical models of singular pairs and its applications
Yuji Odaka, Chenyang Xu
We prove the existence of log canonical modifications for a log pair. As an application, together with Kollär's gluing theory, we remove the assumption in the first named author's…
Fourier-Mukai transforms and the wall-crossing behavior for Bridgeland's stability conditions
Hiroki Minamide, Shintarou Yanagida, Kota Yoshioka
Bridgeland stability condition is preserved under the Fourier-Mukai transform by its definition. We explain the relation with Gieseker stability. By studying the wall-crossing beha…
Displacement energy of unit disk cotangent bundles
Kei Irie
We give an upper bound of a Hamiltonian displacement energy of a unit disk cotangent bundle in a cotangent bundle , when the base manifold is an open Riemannian ma…
Non-left-orderable double branched coverings
Tetsuya Ito
We develop a method to show the fundamental group of the double branched covering of a link is not left-orderable by introducing the notion of the coarse presentation. As in the us…
Ludics with repetitions (Exponentials, Interactive types and Completeness)
Claudia Faggian, Michele Basaldella
Ludics is peculiar in the panorama of game semantics: we first have the definition of interaction-composition and then we have semantical types, as a set of strategies which "behav…
Lagrangian Floer theory over integers: spherically positive symplectic manifolds
Kenji Fukaya, Yong-Geun Oh, Hiroshi Ohta +1
In this paper we study the Lagrangian Floer theory over or . Under an appropriate assumption on ambient symplectic manifold, we show that the whole story of Lagrangian F…
Spectral invariants with bulk, quasimorphisms and Lagrangian Floer theory
Kenji Fukaya, Yong-Geun Oh, Hiroshi Ohta +1
In this paper we first develop various enhancements of the theory of spectral invariants of Hamiltonian Floer homology and of Entovi-Polterovich theory of spectral symplectic quasi…
A low-Reynolds-number treadmilling swimmer near a semi-infinite wall
Kiori Obuse, Jean-Luc Thiffeault
We investigate the behavior of a treadmilling microswimmer in a two-dimensional unbounded domain with a semi-infinite no-slip wall. The wall can also be regarded as a probe or pipe…
Geometry and Combinatorics of Crystal Melting
Masahito Yamazaki
We survey geometrical and especially combinatorial aspects of generalized Donaldson-Thomas invariants (also called BPS invariants) for toric Calabi-Yau manifolds, emphasizing the r…
On the universal sl_2 invariant of boundary bottom tangles
Sakie Suzuki
The universal sl_2 invariant of bottom tangles has a universality property for the colored Jones polynomial of links. Habiro conjectured that the universal sl_2 invariant of bounda…
Simply connected surfaces of general type in positive characteristic via deformation theory
Yongnam Lee, Noboru Nakayama
Algebraically simply connected surfaces of general type with p_g=q=0 and 1\le K^2\le 4 in positive characteristic (with one exception in K^2=4) are presented by using a Q-Gorenstei…
On the higher Fitting ideals of Iwasawa modules of ideal class groups over real abelian fields
Tatsuya Ohshita
Kurihara established a refinement of the minus-part of the Iwasawa main conjecture for totally real number fields using the higher Fitting ideals. In this paper, by using Kurihara'…
