Abstract
The Lorentz solution for Stokes flow in the presence of a plane wall is gen eralized to a surfactant-covered interface, and the Stokeslet solution is d erived. The result is used to describe the motion of a small particle in th e presence of the interface. The surfactant is insoluble and nondiffusing. The effects of surface viscosity are included. Small variations in surfacta nt concentration are assumed; this assumption usually holds under small cap illary number conditions. (C) 1999 American Institute of Physics. [S1070-66 31(99)02902-5].
