On asymptotic ruin probability for a bidimensional renewal risk model with dependent and subexponential main claims and delayed claims Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2024-03-17 Yueli Yang, Bingzhen Geng, Shijie Wang
In this paper, we consider a bidimensional renewal risk model with dependent main claims and delayed claims. Concretely, suppose that an insurance company simultaneously operates two kinds of businesses which separately trigger two types of claims named main claims and delayed claims, respectively, the two lines of businesses share a common claim-arrival counting process, and the random pairs from

A criterion for the positive semidefiniteness of a diffusivity function Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2024-03-15 Caili Sang, Jianxing Zhao
In magnetic resonance imaging, high angular resolution diffusion imaging (abbr. HARDI) is used to characterize non-Gaussian diffusion processes. One approach to analyzing HARDI data is to model the apparent diffusion coefficient with higher order diffusion tensors from a diffusivity function. An intrinsic property of the diffusivity function is positive semi-definite, which reflects the phenomenon

Structure of the least square solutions to overdetermined systems and its applications to practical inverse problems Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2024-03-05
Abstract In this paper, we study the structure of the least square solutions to overdetermined systems with no solution. In the main theorem, we prove that if an overdetermined system with no solution is deformed into a system of linear equations by the semi-equivalent deformations defined in this paper, then an approximate solution to the original overdetermined system with no solution can be given

A note on Oishi’s lower bound for the smallest singular value of linearized Galerkin equations Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2024-02-09
Abstract Recently Oishi published a paper allowing lower bounds for the minimum singular value of coefficient matrices of linearized Galerkin equations, which in turn arise in the computation of periodic solutions of nonlinear delay differential equations with some smooth nonlinearity. The coefficient matrix of linearized Galerkin equations may be large, so the computation of a valid lower bound of

An inexact fixed point iteration method for solving absolute value equation Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2024-01-03 Xin-Mei Lv, Shu-Xin Miao
The fixed point iteration method is an effective method for solving absolute value equation via equivalent two-by-two block form. To further improve the computational efficiency of the fixed point iteration method, by using the preconditioned shift-splitting strategy, we propose an inexact fixed point iteration method for solving absolute value equation in this paper. We obtain some convergence conditions

Computing the Brauer group of the product of two elliptic curves over a finite field Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2023-12-28 Akira Katayama, Masaya Yasuda
We discuss how to compute the Brauer group of the product of two elliptic curves over a finite field. Specifically, we apply the Artin–Tate formula for abelian surfaces to give a simple formula for computing the order of the Brauer group of the product of two elliptic curves. Our formula enables to compute the order of the Brauer group using traces of Frobenius maps on elliptic curves and the discriminant

On a certain martingale representation and the related infinite dimensional moment problem Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2023-10-06 Yuma Tamura
It is well-known that any \(L^2\)-martingale with respect to a Brownian filtration is represented by a stochastic integral with respect to the Brownian motion. The theorem can be proven based on the fact that linear combinations of exponential martingales (of a specific type) are dense in the mentioned set. In this paper, the necessary and sufficient conditions for expressing martingales as true identities

In this expository article, we present a systematic formal derivation of the Kubo formula for the linear-response current due to a time-harmonic electric field applied to non-interacting, spinless charged particles in a finite volume in the quantum setting. We model dissipation in a transparent way by assuming a sequence of scattering events occurring at random-time intervals modeled by a Poisson distribution

The strong ellipticity condition (abbr.

Existing literature shows that it can be equivalently transformed into the SE-condition of an elasticity tensor, and that the SE-condition of an elasticity tensor holds if and only if all of its M-eigenvalues

Convergence analysis of approximation formulas for analytic functions via duality for potential energy minimization Japan J. Indust. Appl. Math. (IF 0.9) Pub Date : 2023-05-04 Satoshi Hayakawa, Ken’ichiro Tanaka
We investigate the approximation formulas that were proposed by Tanaka & Sugihara (IMA J. Numer. Anal. 39(4):1957–1984, 2019), in weighted Hardy spaces, which are analytic function spaces with certain asymptotic decay. Under the criterion of minimum worst error of n-point approximation formulas, we demonstrate that the formulas are nearly optimal. We also obtain the upper bounds of the approximation
