Positive solutions for a class of superlinear semipositone systems on exterior domains [PDF]
We study the existence of a positive radial solution to the nonlinear eigenvalue problem −Δu=λK1(|x|)f(v) in Ωe, −Δv=λK2(|x|)g(u) in Ωe, u(x)=v(x)=0 if |x|=r0 (>0), u(x)→0, v(x)→0 as |x|→∞, where λ>0 is a parameter, Δu=div(∇u) is the Laplace operator, Ωe=

Nonlinear fourth order boundary value problem [PDF]
In this paper we consider a nonlinear boundary value problem generated by a fourth order differential equation on the semi-infinite interval in which the lim-4 case holds for fourth order differential expression at infinity.

Exact boundary behavior of the unique positive solution for singular second-order differential equations [PDF]
In this paper, we give the exact asymptotic behavior of the unique positive solution to the following singular boundary value problem \begin{equation*} \begin{cases} -\frac{1}{A}(Au^{\prime })^{\prime }=p(x)g(u),\quad x\in (0,1), \\ u>0,\quad \text{in ...

Multiplicity of positive solutions to second-order singular differential equations with a parameter
We study the existence and multiplicity of positive periodic solutions for second-order nonlinear damped differential equations by combing the analysis of positiveness of the Green function for a linear damped equation.

Existence results for a fourth order partial differential equation arising in condensed matter physics [PDF]
We study a higher order parabolic partial differential equation that arises in the context of condensed matter physics. It is a fourth order semilinear equation whose nonlinearity is the determinant of the Hessian matrix of the solution. We consider this
