Semilinear PDEs and some symmetry properties of stable solutions
I will deal with stable solutions of semilinear elliptic PDE's and some of their symmetry's properties. Moreover, I will introduce some weighted Poincaré inequalities obtained by combining the notion of stable solution with the definition of weak solution.

Phase transition for higher dimensional wells
Abstract. For a potential function $F$ that has two global minimum sets consisting of two compact connected Riemannian submanifolds in $R^k$, we consider the singular perturbation problem:
Minimizing $\int (|\nabla u|^2+\frac{1}{\epsilon2} F(u))$ under given Dirichlet boundary data.
I will discuss a recent joint work with F.H.Lin and X.B.Pan on the asymptotic, as the parameter $\epsilon$ tends to zero, in terms of the area of minimal hypersurface interfaces, the minimal connecting energy, and the energy of minimizing harmonic maps into the phase manifolds under both Dirichlet and partially free boundary data. Our results in particular addressed the static case of the so-called Keller-Rubinstein-Sternberg problem.
