Quasilinear dirichlet problems in RN with critical growth

open access: yes, 2001
In this study, a given quasilinear problem is solved using variational methods. In particular, the existence of nontrivial solutions for GP is examined using minimax methods.

Existence and multiplicity of nontrivial solutions for quasilinear elliptic systems

open access: yes, 2011
The existence and multiplicity of nontrivial solutions are obtained for the quasilinear elliptic systems by the linking argument, the cohomological index theory and the pseudo-index ...

Potential theory for quasiliniear elliptic equations

open access: yesElectronic Journal of Differential Equations, 2001
We discuss the potential theory associated with the quasilinear elliptic equation $$ -{ m div}(A(x,abla u))+B(x,u)=0. $$ We study the validity of Bauer convergence property, the Brelot convergence property.

Soliton solutions for quasilinear Schrödinger equations: the critical exponential case

open access: yes, 2007
Quasilinear elliptic equations in R2 of second order with critical exponential growth are considered. By using a change of variable, the quasilinear equations are reduced to semilinear equations, whose respective associated functionals are well defined ...

Soliton solutions for a quasilinear Schrodinger equation

open access: yesElectronic Journal of Differential Equations, 2013
In this article, critical point theory is used to show the existence of nontrivial weak solutions to the quasilinear Schrodinger equation $$ -\Delta_p u-\frac{p}{2^{p-1}}u\Delta_p(u^2)=f(x,u) $$ in a bounded smooth domain $\Omega\subset\mathbb{R}^{N}

Multiple positive solutions for quasilinear problems with indefinite sublinear nonlinearity

open access: yes, 2015
We have established multiplicity of nontrivial solutions for the quasilinear elliptic problem -Delta(p)u = h(x)u(alpha-1) + g(x, u) in Omega u >= 0 in Omega, u = 0 on partial derivative Omega where Omega subset of R(N) smooth bounded domain, p > 1, 1

Dirichlet problem for quasi-linear elliptic equations

open access: yesElectronic Journal of Differential Equations, 2002
We study the Dirichlet Problem associated to the quasilinear elliptic problem $$ -sum_{i=1}^{n}frac{partial }{partial x_i}mathcal{A}_i(x,u(x), abla u(x))+mathcal{B}(x,u(x),abla u(x))=0.

Quasilinear Control Theory for Systems with Asymmetric Actuators and Sensors. [PDF]

open access: yes, 2013
Quasilinear Control (QLC) theory provides a set of methods for analysis and design of systems with nonlinear actuators and sensors. In practice, actuators always saturate and sensors often have deadzone or quantization.
