Quasilinear asymptotically periodic Schrödinger–Poisson system with subcritical growth

open access: yesBoundary Value Problems, 2020
The aim of this paper is establishing the existence of a nontrivial solution for the following quasilinear Schrödinger–Poisson system: { − Δ u + V ( x ) u − u Δ ( u 2 ) + K ( x ) ϕ ( x ) u = g ( x , u ) , x ∈ R 3 , − Δ ϕ = K ( x ) u 2 , x ∈ R 3 , u ∈ H 1

Existence of ground state solutions for quasilinear Schrödinger equations with general Choquard type nonlinearity

open access: yesBoundary Value Problems, 2020
In this paper, we study the following Choquard type quasilinear Schrödinger equation: − Δ u + u − Δ ( u 2 ) u = ( I α ∗ G ( u ) ) g ( u ) , x ∈ R N , $$ -\Delta u+u-\Delta \bigl(u^{2}\bigr)u=\bigl(I_{\alpha }*G(u) \bigr)g(u),\quad x\in {\mathbb{R}}^{N}, $

Remarks on the Controllability of Some Quasilinear Equations [PDF]

open access: yesarXiv, 2009
In this Note, we review the main existing results, methods, and some key open problems on the controllability of nonlinear hyperbolic and parabolic equations. Especially, we describe our recent universal approach to solve the local controllability problem of quasilinear time-reversible evolution equations, which is based on a new unbounded perturbation

Nonlinear Muckenhoupt-Wheeden type bounds on Reifenberg flat domains, with applications to quasilinear Riccati type equations [PDF]

open access: yesarXiv, 2013
A weighted norm inequality of Muckenhoupt-Wheeden type is obtained for gradients of solutions to a class of quasilinear equations with measure data on Reifenberg flat domains. This essentially leads to a resolution of an existence problem for quasilinear Riccati type equations with a gradient source term of arbitrary power law growth.

Global solutions of quasilinear systems of Klein--Gordon equations in 3D [PDF]

open access: yesarXiv, 2012
We prove small data global existence and scattering for quasilinear systems of Klein-Gordon equations with different speeds, in dimension three. As an application, we obtain a robust global stability result for the Euler-Maxwell equations for electrons.

The class of second order quasilinear equations: models, solutions and background of classification [PDF]

open access: yesarXiv, 2017
The paper is concerned with the unsteady solutions to the model of mutually penetrating continua and quasilinear hyperbolic modification of the Burgers equation (QHMB). The studies were focused on the peculiar solutions of models in question. On the base of these models and their solutions, the ideas of second order quasilinear models classification ...
