DEF

On a surface, the place having a local curvature less than zero.

CONT

In the simplest non-linear Langevin equation, the first term describes the relaxation of the interface due to the surface tension. Its meaning is quite obvious: protrusions (places with local curvature less than zero) tend to disappear under the influence of the smoothing effect of surface tension.

CONT

In solidification terms, if the surface has a part with positive curvature (bump), the molecules in this region can leave the surface easier because the molecules on the surface have fewer neighbours with attractive interactions bonding them to the growing phase. For places with negative curvature the situation is reversed.

CONT

bump function.
