Abstract
The limits of using retarded motion expansions of simple fluid theory are examined. The possible existence of two types of instability for parallel flows of second-order fluids is shown. For one of these instabilities the second-order fluid assumptions are not valid and mathematical stability results do not bear any relation to real fluid behavior in this region. Apparent contradictions in previous papers are resolved.Keywords
