Partial regularity for quasilinear nonuniformly elliptic systems

open access: yesLe Matematiche, 1991
We prove the partial regularity of the weak solutions of the quasilinear nonuniformely elliptic system div(A(∇u))=0 under an ellipticity condition which lies between strong ellipticity and Legendre-Hadamard condition.

Existence result of continuous positive solutions for a reaction–diffusion system

open access: yesPartial Differential Equations in Applied Mathematics
This paper mainly seeks to contribute to the study of a quasilinear parabolic reaction–diffusion system of arbitrary order with initial conditions. Using potential analysis techniques, we establish the existence of continuous positive solutions.

Equivalent Nonlinearization Technique for Random Analysis of Nonlinear System With Fractional Derivative Damping

open access: yesShock and Vibration
Solving nonlinear systems with fractional derivative damping is often challenging, particularly in cases of strong damping and excitation. To derive solutions for such strong nonlinear systems more concisely, this manuscript presents an approximate ...

Existence of weak solutions for quasilinear parabolic systems in divergence form with variable growth

open access: yesElectronic 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 ...
