Global Convergence of Multiplicative Updates for the Matrix Mechanism: A Collaborative Proof with Gemini 3
Keith Rush
We analyze a fixed-point iteration arising in the optimization of a regularized nuclear norm objective involving the Hadamard product structure, posed in DMR+22…

Randomized Verblunsky Parameters in Steklov's Problem
Keith Rush
We consider randomized Verblunsky parameters for orthogonal polynomials on the unit circle as they relate to the problem of Steklov, bounding the polynomials' uniform norm independ…

On Schur parameters in Steklov's problem
S. Denisov, K. Rush
We study the recursion (aka Schur) parameters for monic polynomials orthogonal on the unit circle with respect to a weight which provides negative answer to the conjecture of Stekl…
