Moment-sequence transforms
Alexander Belton, Dominique Guillot, Apoorva Khare +1
We classify all functions which, when applied term by term, leave invariant the sequences of moments of positive measures on the real line. Rather unexpectedly, these functions are…
Model-free consistency of graph partitioning
Peter Diao, Dominique Guillot, Apoorva Khare +1
In this paper, we exploit the theory of dense graph limits to provide a new framework to study the stability of graph partitioning methods, which we call structural consistency. Bo…
Schur polynomials and matrix positivity preservers
Alexander Belton, Dominique Guillot, Apoorva Khare +1
A classical result by Schoenberg (1942) identifies all real-valued functions that preserve positive semidefiniteness (psd) when applied entrywise to matrices of arbitrary dimension…
