Abstract

A sphere theorem for non-axisymmetric Stokes flow of a viscous fluid of viscosity m^e past a fluid sphere of viscosity mⁱ is stated and proved. The existing sphere theorems in Stokes flow follow as special cases from the present theorem. It is observed that the expression for drag on the fluid sphere is a linear combination of rigid and shear-free drags.
