errant

PHR: corps vagabond, ensemble non vagabond, attractif vagabond, mobile vagabond, point vagabond, point non vagabond.

OBS: Questions of vocabulary: ""laplacian,"" ""benign,"" or ""settled"" vs. ""vagrant"". Again, new terms become indispensable. Let me hereby recommend settled as (a) a synonym of what mathematicians call ""stationary and such that X (t) converges to B(t),"" and (b) a term for the intuitive idea certain practitioners tend to call ""stationarity"". The alternative antonyms would be unsettled and vagrant.
