On positive definite thresholding of correlation matrices
Sujit Sakharam Damase, James Eldred Pascoe
Standard thresholding techniques for correlation matrices often destroy positive semidefiniteness. We investigate the construction of positive definite functions that vanish on spe…

Complete discrete Schoenberg-Delsarte theory for homogeneous spaces
Sujit Sakharam Damase, James Eldred Pascoe
We develop a theory of partially defined complete positivity preservers, extending Schoenberg's classical characterization to functions defined only on discrete subsets or constrai…

The outer spectral radius and dynamics of completely positive maps
J. E. Pascoe
We examine a special case of an approximation of the joint spectral radius given by Blondel and Nesterov, which we call the outer spectral radius. The outer spectral radius is give…
