Uniqueness of the Positive Solution of Δu + f(u) = 0 in an Annulus
We give here an extension of the recent result of Kwong (which in turn extended earlier results of Coffman and McLeod and Serrin) on the uniqueness of the positive radial solution of a semilinear elliptic equation.

Asymptotics of a Free Boundary Problem
As was shown by Kaper and Kwong [Differential and Integral Equations 3, 353--362], there exists a unique R ? 0, such that the differential equation u 00 + 2 + 1 r u 0 + u \Gamma u q = 0; r ? 0; (0 q !

On a Volume Constrained Variational Problem
Existence of minimizers for a volume constrained energy E(u) := Z \Omega W (ru)dx where L N (fu = z i g) = ff i ; i = 1; : : : ; P; is proved in the case where z i are extremal points of a compact, convex set in R d and under suitable assumptions ...

Strongly indefinite systems with critical Sobolev exponents
We consider an elliptic system of Hamiltonian type on a bounded domain. In the superlinear case with critical growth rates we obtain existence and positivity results for solutions under suitable conditions on the linear terms.

Modulus continuity estimates for weak solutions of Laplace equation and Heat equation
In this paper, we employ the perturbation method to study the modulus continuity estimates for Laplace equation and heat equation .Firstly, we investigate the modulus continuity estimate for the H1 weak solutions of the Laplace equation ∆ux=fx, x∈B1 on ...
