Massive Particle Systems, Wasserstein Brownian Motions, and the Dean-Kawasaki Equation
Lorenzo Dello Schiavo
We develop a unifying theory for four different objects: (1) infinite systems of interacting massive particles; (2) solutions to the Dean-Kawasaki equation with singular drift and…

Ill-posedness of the pure-noise Dean-Kawasaki equation
Lorenzo Dello Schiavo, Vitalii Konarovskyi
We prove that the Dean-Kawasaki-type stochastic partial differential equation with vector-valu…

Conformally invariant random fields, quantum Liouville measures, and random Paneitz operators on Riemannian manifolds of even dimension
Lorenzo Dello Schiavo, Ronan Herry, Eva Kopfer +1
For large classes of even-dimensional Riemannian manifolds , we construct and analyze conformally invariant random fields. These centered Gaussian fields , called co-…
