Abstract
In this paper we discuss some features of systems of partial differential equations of first order related to change of type, to composite type and to degeneracy. We are interested in these effects with respect to viscoelastic fluid flow and hence we focus on the properties of two particular models of differential type, the Upper Convected Maxwell model and the Bird-DeAguiar model. Friedrichs’ theory of symmetric positive operators is discussed as a means for treating these indefinite type systems and its use is illustrated for two simple systems, one of composite type and one of degenerate elliptic type.
