✦ Synopsis
Many glass formers show the simultaneously existence of two or more relevant elementary processes ((Y, /3, . ..). The extrapolation of (Y and PJG (Johari-Goldstein) processes to higher temperatures leads often to a bifurcation like behavior of these processes& will be predicted that in general a crossing or a real bifurcation between an (Y process and pJG process is excluded. Both processes avoid each other near and above the apparent bifurcation region. Furthermore, the (Y process shows strong decreasing of the intensity with increasing temperature close to this regime. @ 1999 Elsevier Science B.V.
