Blowup of small data solutions for a quasilinear wave equation in two space dimensions

, 1998
For the quasilinear wave equation \partial_t^2u - \Delta u = u_t u_{tt}, we analyze the long-time behavior of classical solutions with small (not rotationally invariant) data.

Partial regularity for quasilinear nonuniformly elliptic systems

Le 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

Partial 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.

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

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 ...

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

Shock 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 ...
