Description
The book is an almost self-contained presentation of the most important concepts and results in viability and invariance. The viability
of a set K with respect to a given function (or multi-function) F, defined on it, describes the property that, for each initial data
in K, the differential equation (or inclusion) driven by that function or multi-function) to have at least one solution. The invariance
of a set K with respect to a function (or multi-function) F, defined on a larger set D, is that property which says that each solution
of the differential equation (or inclusion) driven by F and issuing in K remains in K, at least for a short time.
The book includes
the most important necessary and sufficient conditions for viability starting with Nagumo’s Viability Theorem for ordinary differential
equations with continuous right-hand sides and continuing with the corresponding extensions either to differential inclusions or to semilinear
or even fully nonlinear evolution equations, systems and inclusions. In the latter (i.e. multi-valued) cases, the results (based on two
completely new tangency concepts), all due to the authors, are original and extend significantly, in several directions, their well-known
classical counterparts.
