Abstract: A general theory is presented to calculate the wave vector and frequency dependent effective viscosity of a suspension of spheres. The resulting formal expression for the effective viscosity is then used to evaluate the coefficients of the linear and the quadratic terms in an expansion in the volume fraction of the spheres using stick boundary conditions. On the linear level the well-known Einstein result is obtained. On the quadratic level we find that it is not justified to neglect higher order spatial derivatives of the secondary velocity fields as done in the analysis by Peterson and Fixman. As a consequence we find a value for the Huggins coefficient which is 12% higher than their value.
