Quasilinear Theory for Relativistic Particles [PDF]

open access: yesAmerican Journal of Modern Physics, 2014
Quasilinear theory is developed by using canonical variables for relativistic particles. It is self-consistent, including momentum, pitch-angle, and spatial diffusions. By assuming the wave field is a superposition of known toroidal and poloidal Fourier modes, the quasilinear diffusion coefficients are written in a form which can be directly evaluated ...

Satisficing, aggregation, and quasilinear utility

open access: yesQuantitative Economics, Volume 17, Issue 2, Page 431-460, May 2026.
This paper studies approximation error in the quasilinear utility model. Error arises because individuals do not perfectly optimize, and instead satisfice. We investigate the consequences of individual satisficing for modeling aggregate demand, providing an approximate aggregation theorem.

A Quasilinear Parabolic Equation with Quadratic Growth of the Gradient modeling Incomplete Financial Markets [PDF]

open access: yes
We consider a quasilinear parabolic equation with quadratic gradient terms. It arises in the modelling of an optimal portfolio which maximizes the expected utility from terminal wealth in incomplete markets consisting of risky assets and non-tradable ...

Simple incentives and diverse beliefs

open access: yesTheoretical Economics, Volume 21, Issue 2, Page 500-534, May 2026.
This paper studies a moral hazard problem in which the principal does not know the agent's beliefs about the output generating process. The agent is risk neutral, transfers are subject to limited liability, and the principal evaluates contracts according to their worst‐case payoff against a rich set of plausible agent beliefs.

Lie-transform derivation of oscillation-center quasilinear theory

open access: yesFundamental Plasma Physics
The derivation of the oscillation-center quasilinear theory in an unmagnetized plasma by Dewar (1973) is rederived by Lie-transform perturbation method.

Unified Quasilinear Theory of Weakly Turbulent Plasmas [PDF]

open access: yesThe Physics of Fluids, 1968
A quasilinear theory is formulated which includes the microscopic fluctuation fields as well as the coherent waves. The study emphasizes those cases in which the propagating mode of the fluctuation field gives rise to a dominant contribution to the particle correlation.

Parker Solar Probe Observations of Proton Core‐Beam Distributions in Heliospheric Current Sheet Region: Quasilinear Instability Analysis Combined With Collisional Relaxation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Parker Solar Probe has been proven as instrumental for the observation of young solar wind. During the encounters E‐07 and E‐08, PSP recorded the core plus beaming protons crossing the heliospheric current Sheet region. When the observed PSP data is plotted in the temperature ratio versus parallel beta space, it is found that the occurrence ...

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.

Weighted function spaces of fractional derivatives for vector fields

open access: yesElectronic Journal of Differential Equations, 2007
We introduce and study weighted function spaces for vector fields from the point of view of the regularity theory for quasilinear subelliptic PDEs.
