✦ Synopsis

We report on rigorous results for self-diffusion in stochastic lattice gases: (1) scaling limit and convergence to Brownian motion, (ii) a variational formula for the tracer diffusion coefficient D, (iii) strict positivity of D except for lattice gases in one dimension with nearest neighbor jumps only, (iv) long time tails.
