Critical parameter equations for degenerate parabolic equations coupled via nonlinear boundary flux
This paper deals with the critical parameter equations for a degenerate parabolic system coupled via nonlinear boundary flux. By constructing the self-similar supersolution and subsolution, we obtain the critical global existence parameter equation.

Blow-Up and Global Existence for a Degenerate Parabolic System with Nonlocal Sources
This paper investigates the blow-up and global existence of nonnegative solutions for a class of nonlocal degenerate parabolic system. By using the super- and subsolution techniques, the critical exponent of the system is determined. That is, if Pc=p1q1−(

Existence and nonexistence results for quasilinear semipositone Dirichlet problems
We use the sub/supersolution method to analyze a semipositone Dirichlet problem for the p-Laplacian. To find a positive solution, we therefore focus on a related problem that produces positive subsolutions.

Subsolution theorem for the complex Hessian equation
We prove the subsolution theorem for the complex Hessian equations in a smoothly bounded strongly $m$-pseudoconvex domain, $1 < m < n$, in $\bC^n$.

The Obstacle Problem for the A-Harmonic Equation
Firstly, we define an order for differential forms. Secondly, we also define the supersolution and subsolution of the A-harmonic equation and the obstacle problems for differential forms which satisfy the A-harmonic equation, and we obtain the relations ...

Entire subsolutions of fully nonlinear degenerate elliptic equations
We prove existence and non existence results for fully nonlinear degenerate elliptic inequalities by showing that the classical Keller–Osserman condition on the zero order term is a necessary and sufficient condition for the existence of entire sub solutions.
