Uniform-in-Time Boltzmann Mean-Field Limits for Anchored Binary Opinion Dynamics
Jingyi Zhang, Debankur Mukherjee
We study a continuous-time opinion model in which agents interact in pairs and each agent has a fixed anchor. At each interaction, both opinions are updated according to a possibly…

Scaling Limits of Constant-Stepsize SGD at Flat Minima
Jingyi Zhang, Cheng Mao, Debankur Mukherjee
For stochastic gradient descent (SGD) with a constant stepsize , the invariant law of the iterates, centered at a minimizer, describes the behavior of the algorithm over long ti…
