椭圆型方程组的几何不等式和对称性结果

Geometric inequalities and symmetry results for elliptic systems

Serena Dipierro

摘要:

我们得到了一些Poincaré型公式,我们使用这些公式,结合水平集分析,来检测形式为{eqnarray *}{{array}{ll} div(a)的可能退化椭圆型方程组的单调稳定解的一维对称性。|\nabla使用|)\nabla u)= F_1(u,v),div(b(|\nabla v|)\nabla v)= F_2(u,v),{array}. {eqnarray *}其中$F\in C^{1,1}_{loc}(\R^2)$。我们的设置是非常普遍的,它包括,作为一个特殊的情况下,德乔治的猜想相分离$\R^2$。

英文摘要:

We obtain some Poincaré type formulas, that we use, together with the level set analysis, to detect the one-dimensional symmetry of monotone and stable solutions of possibly degenerate elliptic systems of the form {eqnarray*} {{array}{ll} div(a(|\nabla u|) \nabla u) = F_1(u, v), div(b(|\nabla v|) \nabla v) = F_2(u, v), {array}. {eqnarray*} where $F\in C^{1,1}_{loc}(\R^2)$. Our setting is very general, and it comprises, as a particular case, a conjecture of De Giorgi for phase separations in $\R^2$.
