Nobusumi Sagara

摘要:

本文证明了饱和是测度空间上的一个不可缺少的结构,从而得到了巴拿赫空间及其对偶空间中带积分约束的非凸变分问题解的存在性和特征.我们提供了一个最优性的表征通过最大值原理的哈密顿和存在的结果没有纯化的放松控制,其中的李雅普诺夫凸性定理在无限维的饱和假设下的基础测度空间起着至关重要的作用。我们还证明了某些基元的解的存在性是测度空间饱和的充分必要条件。

英文摘要:

This paper exemplifies that saturation is an indispensable structure on measure spaces to obtain the existence and characterization of solutions to nonconvex variational problems with integral constraints in Banach spaces and their dual spaces. We provide a characterization of optimality via the maximum principle for the Hamiltonian and an existence result without the purification of relaxed controls, in which the Lyapunov convexity theorem in infinite dimensions under the saturation hypothesis on the underlying measure space plays a crucial role. We also demonstrate that the existence of solutions for certain class of primitives is necessary and sufficient for the measure space to be saturated.
