摘要:

我们证明了一个最初源于基本递归迭代方案(通常称为“Kaczmarz算法”)的想法,在无限维和非交换的设置中具有重要应用,这些设置是算子在希尔伯特空间中的谱理论、优化、大规模稀疏系统、迭代函数系统(IFS)和分形调和分析的核心。我们提出了一种新的递归迭代方案,输入为预设的自 adjoint 投影序列。应用包括随机 Kaczmarz 递归、其极限和误差估计。

英文摘要:

We show that an idea, originating initially with a fundamental recursive iteration scheme (usually referred as "the" Kaczmarz algorithm), admits important applications in such infinite-dimensional, and non-commutative, settings as are central to spectral theory of operators in Hilbert space, to optimization, to large sparse systems, to iterated function systems (IFS), and to fractal harmonic analysis. We present a new recursive iteration scheme involving as input a prescribed sequence of selfadjoint projections. Applications include random Kaczmarz recursions, their limits, and their error-estimates.
