On a quasilinear system arising in the theory of superconductivity

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2011
We examine the regularity of the solution of a quasilinear system involving the curl of vector fields. This system arises in the mathematical theory of superconductivity. The C2+α regularity was obtained by Bates and Pan under the condition that Ω is simply connected and has no holes, and that the normal component of the curl of the boundary data ...

On the validity of quasilinear theory applied to the electron bump-on-tail instability

open access: yesPhysics of Plasmas, 2022
The accuracy of quasilinear theory applied to the electron bump-on-tail instability, a classic model problem, is explored with conservative high-order discontinuous Galerkin methods applied to both the quasilinear equations and to a direct simulation of ...

Quasilinear theory of viscoelasticity

Polymer Mechanics, 1972
By postulating equal contributions the number of kernels in the principal cubic theory of viscoelasticity and in the theory with regular kernels of two arguments is reduced to three. For certain quasilinear relations all the kernels and functions are determined from creep, relaxation, and simple loading and deformation tests.

Inconsistency of quasilinear theory

The Physics of Fluids, 1983
Mode-coupling terms yield non-negligible corrections to the quasilinear terms in the evolution of one-dimensional Langmuir turbulence generated by the weak warm beam instability.

Quasilinear theory of Cherenkov-drift instability

Physical Review E, 2003
We examine linear and quasiliner stages of Cherenkov-drift instability developed in the relativistic magnetized electron-positron plasma penetrated by ultrarelativistic beam of electrons (or positrons). The plasma flow is streaming along the slightly curved magnetic field lines.

Quasilinear Control Theory: An Overview

IFAC Proceedings Volumes, 2011
Abstract This paper presents a complete set of methods for the performance analysis and design of closed loop systems with nonlinear actuators and sensors (so-called Linear Plant/Nonlinear Instrumentation, or LPNI, systems). As it turns out, these methods are quite similar to those in the linear case. Accordingly, the resulting methods are referred to

The Quasilinear Theory

2009
In this chapter, we discuss the interaction between charged particles and an astro- physical plasma. Historically, the first and most applied approach to determine spa- tial diffusion coefficients and other transport parameters is the so-called quasilinear theory (QLT). The quasilinear approximation is comparable to a first-order pertur- bation theory.
