Complex Interpolation of Matrices with an application to Multi-Manifold Learning
arXiv:2604.14118v1 Announce Type: new
Abstract: Given two symmetric positive-definite matrices $A, B \in \mathbb{R}^{n \times n}$, we study the spectral properties of the interpolation $A^{1-x} B^x$ for $0 \leq x \leq 1$. The presence of `common struc…
