4. Noun. (mathematics) (context: of a function) defined for each point $x$ in the domain of the function by $\inf\left\\left\{\mathrm\left\{diam\right\}\left(f\left(U\right)\right)\mid U\mathrm\left\{\ is\ a\ neighborhood\ of\ \right\}x\right\\right\}$, and describes the difference (possibly ?) between the limit superior and limit inferior of the function near that point. ¹
