Abstract
The kinematics required at a fluid interface where tangential componen ts of surface traction vanish are discussed. This condition forces one principal axis of strain to remain aligned with the surface normal. F rom the rotation rate of the surface normal we calculate the vorticity required at the interface. Previous results restricted to special geo metries are generalized and the role of the surface geometry is discus sed.
