-
Compact Support Property of Super-Brownian Motion with Irregular Drift
We prove the compact support property for a one-dimensional super-Brownian motion with irregular drift and establish support-radius estimates and positive extinction probability.
-
Weak Existence and Uniqueness for Super-Brownian Motion with Irregular Drift
We establish weak existence and uniqueness for one-dimensional super-Brownian motion with a broad class of bounded irregular drifts.

Strong Existence and Uniqueness for Singular SDEs Driven by Stable Processes
Published · Annals of Applied Probability 36(2), 1690–1736 (2026). We derive weak and strong well-posedness for one-dimensional stochastic differential equations with measure-valued drift driven by a symmetric stable process…
