Where do solutions go, and how do they behave en route? These are two of the major questions addressed by the qualita- tive theory of differential equations. The purpose of this book is to answer these questions for certain classes of equa- tions by recourse to the framework of semidynamical systems (or topological dynamics as it is sometimes called). This approach makes it possible to treat a seemingly broad range of equations from nonautonomous ordinary differential equa- tions and partial differential equations to stochastic differ- ential equations. The methods are not limited to the...
