摘要：

The Riemann problem for a forward-backward parabolic equation of interest in physical and biological models is studied. A complete classification of suitably defined entropy solutions is provided. Thereafter, the existence and uniqueness of a solution is proven, and its type is identified. (C) 2009 Elsevier B.V. All rights reserved.
