摘要:
缩放相对图(Scaled Relative Graph,SRG)是一种几何工具,可将多值非线性算子的作用映射到二维平面,用于分析大量迭代方法的收敛性。由于 SRG 在线性算子情形下包含谱,因此可将其视为谱向多值非线性算子的推广。在本工作中,我们进一步研究线性算子的 SRG,并刻画分块对角矩阵和正规矩阵的 SRG。
英文摘要:
The Scaled Relative Graph (SRG) is a geometric tool that maps the action of a multi-valued nonlinear operator onto the 2D plane, used to analyze the convergence of a wide range of iterative methods. As the SRG includes the spectrum for linear operators, we can view the SRG as a generalization of the spectrum to multi-valued nonlinear operators. In this work, we further study the SRG of linear operators and characterize the SRG of block-diagonal and normal matrices.
