Complex Interpolation of Matrices with an application to Multi-Manifold Learning

Adi Arbel, Stefan Steinerberger, Ronen Talmon

Given two symmetric positive-definite matrices $A, B \in R^{n \times n}$ , we study the spectral properties of the interpolation $A^{1 - x} B^{x}$ for $0 \leq x \leq 1$ . The pr…

An Efficient Triangulation of $R P^{5}$

Dan Guyer, Stefan Steinerberger, Yirong Yang

We present a $6$ -dimensional centrally symmetric simplicial polytope for which the antipodal quotient of its boundary forms a $24$ -vertex triangulation of the $5$ -dimensional real…
