摘要：

The influence of Hall currents and rotation on the oscillatory flows of an infinite plate is investigated. Exact solutions for the two problems are obtained. The fluid considered is a homogeneous Oldroyd-B. During the mathematical analysis it is found that governing differential equation for steady flow in an Oldroyd-B fluid is identical to that of viscous fluid. Further, it is observed that in absence of the strength of transverse magnetic field (B-0) the solution in resonance case does not satisfy the boundary condition at infinity. Physical significance of mathematical results is also discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
