线能量下半连续性的一个必要条件

A necessary condition for lower semicontinuity of line energies

Pierre Bochard, Antonin Monteil

摘要:

我们感兴趣的是一些能量泛函集中在不连续线上的发散自由的二维向量场值在圆$\mathbb{S}^1$。这种能量首先由P.Aviles和Y.十亿他们特别表明,与立方费用函数$f(t)=t^3$,这个能量是较低的连续性。本文构造了一个反例,它排除了$t^p$与$0<p<1$形式的费用函数的线能量的下半连续性.我们还表明,在这种情况下,对应于某一凸域的黏性解不是极小。

英文摘要:

We are interested in some energy functionals concentrated on the discontinuity lines of divergence-free 2D vector fields valued in the circle $\mathbb{S}^1$. This kind of energy has been introduced first by P. Aviles and Y. Giga. They show in particular that, with the cubic cost function $f(t)=t^3$, this energy is lower semicontinuous. In this paper, we construct a counter-example which excludes the lower semicontinuity of line energies for cost functions of the form $t^p$ with $0<p<1$. We also show that, in this case, the viscosity solution corresponding to a certain convex domain is not a minimizer.
