A Short Proof of Strassen's Theorem Using Convex Analysis
Benjamin Armbruster
We give a simple proof of Strassen's theorem on stochastic dominance using linear programming duality, without requiring measure-theoretic arguments. The result extends to generali…

A simple and general proof for the convergence of Markov processes to their mean-field limits
Benjamin Armbruster
Mean-field models approximate large stochastic systems by simpler differential equations that are supposed to approximate the mean of the larger system. It is generally assumed tha…
