Finding New Debris Discs at Sub-millimetre Wavelengths
Mark Booth, Patricia Luppe, Sebastian Marino +9
Debris discs reveal the architectures and dynamical histories of planetary systems. Sub-millimetre observations trace large dust grains within debris discs, revealing their bulk pr…
Type-Based Verification of Connectivity Constraints in Lattice Surgery
Ryo Wakizaka, Yasunari Suzuki, Atsushi Igarashi
Fault-tolerant quantum computation using lattice surgery can be abstracted as operations on graphs, wherein each logical qubit corresponds to a vertex of the graph, and multi-qubit…
The lifespan of classical solutions of one dimensional wave equations with semilinear terms of the spatial derivative
Takiko Sasaki, Shu Takamatsu, Hiroyuki Takamura
This paper is devoted to the lifespan estimates of small classical solutions of the initial value problems for one dimensional wave equations with semilinear terms of the spatial d…
The generalized combined effect for one dimensional wave equations with semilinear terms including product type
Ryuki Kido, Takiko Sasaki, Shu Takamatsu +1
We are interested in the so-called "combined effect" of two different kinds of nonlinear terms for semilinear wave equations in one space dimension. Recently, the first result with…
Hunting for quantum-classical crossover in condensed matter problems
Nobuyuki Yoshioka, Tsuyoshi Okubo, Yasunari Suzuki +2
The intensive pursuit for quantum advantage in terms of computational complexity has further led to a modernized crucial question: {\it When and how will quantum computers outperfo…
The combined effect in one space dimension beyond the general theory for nonlinear wave equations
Katsuaki Morisawa, Takiko Sasaki, Hiroyuki Takamura
In this paper, we show the so-called "combined effect" of two different kinds of nonlinear terms for semilinear wave equations in one space dimension. Such a special phenomenon app…
Rule 184 fuzzy cellular automaton as a mathematical model for traffic flow
Kohei Higashi, Junkichi Satsuma, Tetsuji Tokihiro
The rule 184 fuzzy cellular automaton is regarded as a mathematical model of traffic flow because it contains the two fundamental traffic flow models, the rule 184 cellular automat…
Universal consistency of the -NN rule in metric spaces and Nagata dimension
Benoît Collins, Sushma Kumari, Vladimir G. Pestov
The nearest neighbour learning rule (under the uniform distance tie breaking) is universally consistent in every metric space that is sigma-finite dimensional in the sense…
Revisiting the Human and Nature Dynamics model
Basil Grammaticos, Ralph Willox, Junkichi Satsuma
We present a simple model for describing the dynamics of the interaction between a homogeneous population or society, and the natural resources and reserves that the society needs…
Gradient flow model of mode-III fracture in Maxwell-type viscoelastic materials
Yoshimi Tanaka, Takeshi Takaishi
We formulate a phase field crack growth model for mode III fracture in a Maxwell-type viscoelastic material. To describe viscoelastic relaxation, a field variable of viscously flow…
Discrete Painlevé equations from singularity patterns: the asymmetric trihomographic case
Basil Grammaticos, Alfred Ramani, Ralph Willox +1
We derive the discrete Painlevé equations associated to the affine Weyl group E that can be represented by an (in the QRT sense) "asymmetric" trihomographic system. The m…
Role of self-loop in cell-cycle network of budding yeast
Shu-ichi Kinoshita, Hiroaki S. Yamada
Study of network dynamics is very active area in biological and social sciences. However, the relationship between the network structure and the attractors of the dynamics has not…
Complex pattern formation driven by the interaction of stable fronts in a competition-diffusion system
Lorenzo Contento, Masayasu Mimura
The ecological invasion problem in which a weaker exotic species invades an ecosystem inhabited by two strongly competing native species is modelled by a three-species competition-…
Ecological invasion in competition-diffusion systems when the exotic species is either very strong or very weak
Lorenzo Contento, Danielle Hilhorst, Masayasu Mimura
Reaction-diffusion systems with a Lotka-Volterra-type reaction term, also known as competition-diffusion systems, have been used to investigate the dynamics of the competition amon…
Calculating the algebraic entropy of mappings with unconfined singularities
Alfred Ramani, Basil Grammaticos, Ralph Willox +2
We present a method for calculating the dynamical degree of a mapping with unconfined singularities. It is based on a method introduced by Halburd for the computation of the growth…
A Study to Optimize Heterogeneous Resources for Open IoT
Yoji Yamato, Naoto Hoshikawa, Hirofumi Noguchi +2
Recently, IoT technologies have been progressed, and many sensors and actuators are connected to networks. Previously, IoT services were developed by vertical integration style. Bu…
Multiplicative equations related to the affine Weyl group E
Basil Grammaticos, Alfred Ramani, Ralph Willox +1
We derive integrable equations starting from autonomous mappings with a general form inspired by the multiplicative systems associated to the affine Weyl group E. Five su…
Potential theoretic approach to design of accurate formulas for function approximation in symmetric weighted Hardy spaces
Ken'ichiro Tanaka, Tomoaki Okayama, Masaaki Sugihara
We propose a method for designing accurate interpolation formulas on the real axis for the purpose of function approximation in weighted Hardy spaces. In particular, we consider th…
Exact solution of a delay difference equation modeling traffic flow and their ultra-discrete limit
Keisuke Matsuya, Masahiro Kanai
We consider a car-following model described by a delay difference equation and give its exact solutions that present propagation of a traffic jam. This model is a discrete-time ver…

Basil Grammaticos, Alfred Ramani, Ralph Willox +2
We present a new approach to singularity confinement which makes it an efficient and reliable discrete integrability detector. Our method is based on the full-deautonomisation proc…
