Existence and uniqueness for some equation of a mixed elliptic-hyperbolic type

open access: yesBoundary Value Problems, 2019
In the paper, we prove results on existence and uniqueness of weak solutions for closed Dirichlet problem for a transonic flow model, and interior regularity results are also given in the important special case of the Tricomi equation.

The problem with Saigo operators for a hyperbolic equation that degenerates inside the domain

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
A nonlocal problem is investigated for a degenerate hyperbolic equation $$ |y|^{m} u_{xx}-u_{yy}+a |y|^{\frac{m}{2}-1} u_{x}=0 $$ in a domain bounded by the characteristics of this equation.

CEO‐employee pay ratio disclosure and dividend policy

open access: yesJournal of Financial Research, Volume 49, Issue 2, Page 782-820, Summer 2026.
Abstract We examine whether and how the magnitude of the CEO pay ratio affects dividend policy in the context of inequality‐averse investors. Our results demonstrate a positive association between the two and remain robust to endogeneity concerns. We find that the CEO pay ratios positively affect dividends irrespective of whether CEO compensation ...

THE BOUNDARY VALUE PROBLEM FOR THE GENERALIZED MOISTURE TRANSFER EQUATION [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2018
In mathematical modeling of continuous media with memory, we deal with equations that describe a new type of wave motion, something between ordinary wave diffusion and classical wave propagation. There are fractional differential equations, which are the

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

Approximation of tricomi problem with Neumann boundary condition

open access: yes, 1984
The Tricomi problem with Neumann boundary condition is reduced to a degenerate problem in the elliptic region with a non-local boundary condition and to a Cauchy problem in the hyperbolic region. A variational formulation is given to the elliptic problem

Stochastic Delay Bound Prediction Enabled by Network Calculus in TSN‐5G Cross‐Domain Networks

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
The Industrial Internet's expansion intensifies the need for low‐latency, high‐reliability end‐to‐end deterministic networks. While TSN‐5G integration offers a promising path, complex delay bound prediction and inherent stochastic fluctuations persist as key bottlenecks, causing substantial delay jitter and reliability degradation.
