The challenge to understand the zoo of particle transport regimes during resonant wave-particle interactions for given survey-mode wave spectra

Frontiers in Astronomy and Space Sciences
Quasilinear theories have been shown to well describe a range of transport phenomena in magnetospheric, space, astrophysical and laboratory plasma “weak turbulence” scenarios.

Two-grid virtual element discretization of quasilinear elliptic problem

Mathematical Modelling and Analysis
In this paper a two grid algorithm for quasilinear elliptic problem based on virtual element method (VEM) discretization is proposed. With this new algorithm the solution of a quasilinear elliptic problem on a fine grid is reduced to the solution of a ...

Quasilinearization and approximate quasilinearization for multipoint boundary value problems

Journal of Mathematical Analysis and Applications, 1985
This paper is concerned with multipoint boundary value problems of the form \(x^{(n)}(t)=f(t,x(t),x'(t),...,x^{(q)}(t)),\) \(x(a_ i)=A_{1,i},\) \(x'(a_ i)=A_{2,i},...,x^{(k_ i)}\) \((a_ i)=A_{k_ i+1,i},\) \(1\leq i\leq r\), \(a_ ...

An application of global gradient estimates in Lorentz-Morrey spaces for the existence of stationary solutions to degenerate diffusive Hamilton-Jacobi equations

Electronic Journal of Differential Equations, 2019
In mathematics and physics, the Kardar-Parisi-Zhang equation or quasilinear stationary version of a time-dependent viscous Hamilton-Jacobi equation in growing interface and universality classes is also known as the quasilinear Riccati type equation ...

Existence of positive solutions for generalized quasilinear Schrödinger equations with Sobolev critical growth

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we are devoted to establishing that the existence of positive solutions for a class of generalized quasilinear elliptic equations in $\mathbb{R}^{N}$ with Sobolev critical growth, which have appeared from plasma physics, as well as high ...

Picone-type inequality and Sturmian comparison theorems for quasilinear elliptic operators with p(x)-Laplacians

Electronic Journal of Differential Equations, 2012
A Picone-type inequality for quasilinear elliptic operators with mixed nonlinearities and with p(x)-Laplacian is established, and Sturmian comparison theorems are derived on the basis of the Picone-type inequality.

Holder Solvability of Quasi-Linear Parabolic Systems in the Divergent Form

Pan-American Journal of Mathematics
In this article, we consider a quasilinear parabolic system under fair general conditions with form-boundary conditions on the singular coefficients. We establish the requirements on the structural coefficients of the parabolic system under which the ...

Approximate controllability of quasilinear functional differential equations

Electronic Journal of Differential Equations, 2019
In this article, we study the approximate controllability for quasilinear differential equations with deviating arguments in a Hilbert space. We establish sufficient conditions for the existence of a mild solution. We also obtain sufficient conditions

Almost global well-posedness for quasilinear strongly coupled wave-Klein-Gordon systems in two space dimensions

Forum of Mathematics, Sigma
We prove almost global well-posedness for quasilinear strongly coupled wave-Klein-Gordon systems with small and localized data in two space dimensions. We assume only mild decay on the data at infinity as well as minimal regularity.
