Fluctuations around the mean-field limit for attractive Riesz potentials in the moderate regime
Li Chen, Alexandra Holzinger, Ansgar Jüngel
A central limit theorem is shown for moderately interacting particles in the whole space. The interaction potential approximates singular attractive or repulsive potentials of sub-…
Long-time behavior for discretization schemes of Fokker-Planck equations via couplings
Ansgar Jüngel, Katharina Schuh
Continuous-time Markov chains associated to finite-volume discretization schemes of Fokker-Planck equations are constructed. Sufficient conditions under which quantitative exponent…
Global martingale solutions for a stochastic population cross-diffusion system
Gaurav Dhariwal, Ansgar Jüngel, Nicola Zamponi
The existence of global nonnegative martingale solutions to a stochastic cross-diffusion system for an arbitrary but finite number of interacting population species is shown. The r…
Discrete Bochner inequalities via the Bochner-Bakry-Emery approach for Markov chains
Ansgar Jüngel, Wen Yue
Discrete convex Sobolev inequalities and Beckner inequalities are derived for time-continuous Markov chains on finite state spaces. Beckner inequalities interpolate between the mod…
