研究了定义在无限维空间上的半凹函数的不可微点集的结构。我们证明了奇异集是∞-1可数可正的。此外,我们还给出了奇点是奇异集的传播点的一个充分条件。作为应用,我们考虑抛物型发展方程的Mayer最优控制问题。
We study the structure of the set of points of nondifferentiability of semiconcave functions defined on an infinite dimensional space. We show that the singular set is ∞ — 1 countably rectifiable. Moreover, we give a sufficient condition for a singular point to be a propagation point of the singular set. As an application we consider a Mayer Optimal Control problem for an evolution equation of parabolic type.
