These diffusions are solutions to stochastic differential equations: \\[\\mathrm{d}X_t=\\mathrm{d}B_t-g(t)\\nabla V(X_t-\\bar{\\mu}_t)\\,\\mathrm{d}t,\\] where $\\bar{\\mu}_t$ is the empirical mean of the process $X$, $V$ is an asymptotically strictly convex potential and $g$ is a given function. We study the ergodic behaviour of $X$ and prove that it is strongly related to $g$. Actually, we show that $X$ is ergodic (in the limit quotient sense) if and only if $\\bar{\\mu}_t$ converges a.s.
