Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

The Cost of Convenience: A Hedonic Approach to Travel Time Valuation and Cost‐Benefit Analysis

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT This paper presents a novel revealed‐preference approach to estimating the value of travel time (VTT) and calculating consumer surplus for the economic evaluation of transport infrastructure. Departing from traditional stated‐preference models, we derive time valuations by linking residential rental transactions in Greater Sydney to employment

Iterated discrete Hardy-type inequalities with three weights for a class of matrix operators

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
Iterated Hardy-type inequalities are one of the main objects of current research on the theory of Hardy inequalities. These inequalities have become well-known after study boundedness properties of the multidimensional Hardy operator acting from the ...

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, EarlyView.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Saturation Characteristics of Parallel EMIC Waves in the Inner Magnetosphere

open access: yesGeophysical Research Letters, 2019
In this letter, detailed evolution process of parallel electromagnetic ion cyclotron waves in the inner magnetosphere has been investigated through quasilinear theory. A new saturation has been found to occur after the usual first saturation.

Multiplicity of solutions for Dirichlet boundary conditions of second-order quasilinear equations with impulsive effects

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
This paper deals with the multiplicity of solutions for Dirichlet boundary conditions of second-order quasilinear equations with impulsive effects. By using critical point theory, a new result is obtained.

Evaluation of Resorcinarene Trimer Methanesulfonate Aggregation in the Presence of Inorganic Salts and Biomolecules in Aqueous Solutions Using UV–vis Spectroscopy and Electrophoresis

open access: yesChemPhysChem, Volume 27, Issue 9, 14 May 2026.
UV–vis spectra of resorcinarene trimer methanesulfonate were identified in the presence of inorganic salts, choline, and bovine serum albumin. The origin of the peaks was identified. The absorption dynamic over the course of 5 days revealed that Na+ cations promote supramolecular aggregation while choline hinders it.

Quasilinear theory of non-resonant electromagnetic instabilities

open access: yes, 1992
Our quasilinear theory includes explicitly macroscopic drifts, which are then modified, together with other equilibrium quantities, by the growth of unstable waves.

Quasilinear convexity and quasilinear stars in the ray space of a supertropical quadratic form [PDF]

open access: yes, 2020
Relying on rays, we search for submodules of a module V over a supertropical semiring on which a given anisotropic quadratic form is quasilinear.

Multiple solutions for a nonhomogeneous quasilinear sub-elliptic system with critical growth and logarithmic perturbation

open access: yesDemonstratio Mathematica
The interest of this paper is that we use the critical point theory to prove the existence of a sequence of non-trivial solutions for a class of nonhomogeneous quasilinear Sub-elliptic systems with critical growth and logarithmic perturbation.
