一类凸区域上的变分问题

Variational problems on classes of convex domains

Nicolas Van Goethem

摘要:

本文证明了定义在R^N的一个有界集D内的一类凸区域上的泛函的极小元的存在性。给出了一些应用,特别是证明了二阶和四阶非常系数微分算子以及依赖于椭圆型方程解的积分泛函的特征值在这类区域上可以极小化.这一结果的另一个应用与著名的牛顿最小阻力问题有关。在一般情况下,所有的结果,我们将开发的椭圆算子的任何偶数阶大于0。

英文摘要:

We prove the existence of minimizers for functionals defined over the class of convex domains contained inside a bounded set D of R^N and with prescribed volume. Some applications are given, in particular we prove that the eigenvalues of differential operators of second and fourth order with non-constant coefficients as well as integral functionals depending on the solution of an elliptic equation can be minimized over this class of domains. Another application of this result is related to the famous Newton problem of minimal resistance. In general, all the results we shall develop hold for elliptic operators of any even order larger that 0.
