Chorus Wave–Driven Electron Dynamics in the Van Allen Belts: From Coherence to Diffusion
AGU AdvancesThe Van Allen radiation belts contain relativistic electrons trapped by Earth's magnetic field, posing serious risks to spacecraft. Chorus waves are known to accelerate these electrons via resonant interactions, but these interactions are inherently ...

An elliptic system with logarithmic nonlinearity
Advances in Nonlinear Analysis, 2017 In the present paper, we study the existence of solutions for some classes of singular systems involving the Δp(x){\Delta_{p(x)}} and Δq(x){\Delta_{q(x)}} Laplacian operators. The approach is based on bifurcation theory and the sub-supersolution method

Weak solutions of degenerated quasilinear elliptic equations of higher order
International Journal of Mathematics and Mathematical Sciences, 1996 We prove the existence of weak solutions of higher order degenerated quasilinear elliptic equations. The main tools are the degree theory for generalized monotone mappings and imbedding theorems between weighted Sobolev spaces.

Existence of Quasilinear Neutral Impulsive Integrodifferential Equations in Banach Space
International Journal of Analysis and Applications, 2015 In this paper, we devoted to study the existence of mild solutions for quasilinear impulsive integrodi_erential equation in Banach spaces. The results are established by using Hausdor_'s measure of noncompactness and the _xed point theorems.

Existence of solutions to quasilinear functional differential equations
Electronic Journal of Differential Equations, 2009 In this article we use the theory of C0-semigroup of bounded linear operators to establish the existence and uniqueness of a classical solution to a quasilinear functional differential equation considered in a Banach space.

Quasilinear Evolution Integrodifferential Equations in Banach Spaces
Journal of New Theory, 2019 Existence and uniqueness of local classicalsolutions of the quasilinear evolution integrodifferential equation in Banachspaces are studied. The results are demonstrated by employing the fixed pointtechnique on C_0-semigroup of bounded linear operator. At

Reformulation of quasi-linear theory [PDF]
Journal of Plasma Physics, 1972 A new formulation of quasi-linear theory is presented, which allows for only resonant diffusion, caused by both growing and damped waves. Nonresonant terms do not appear in the diffusion equation, but contribute to wave momentum and energy, and ensure conservation of total momentum and energy.

Electronic Journal of Differential Equations, 2018 In this article we study the existence of weak solutions for quasilinear parabolic system in divergence form with variable growth. By means of Young measures, Galerkin's approximation method and the theory of variable exponents spaces, we obtain the ...

Transport phenomena in a plasma quasilinear theory
Le Matematiche, 1991 Making use of a recently developed quasi-linear formulation of 1D Vlasov equation, we derive the balance relations for the space-averaged distribution function and spectral power density.
