Improved well-posedness for the limit flow of differentiation of roots of polynomials
Charles Bertucci, Valentin Pesce
In this paper, we study the partial differential equation on the circle that was heuristically obtained by Steinerberg [32] on the real line and which represents the evolution of t…

A new approach for the unitary Dyson Brownian motion through the theory of viscosity solutions
Charles Bertucci, Valentin Pesce
In this paper, we study the unitary Dyson Brownian motion through a partial differential equation approach recently introduced for the real Dyson case. The main difference with the…
