Abstract: | The Zeno phenomenon of a switched dynamical system refers to the infinite number of mode switches in finite time. The absence
of this phenomenon is crucial to the numerical simulation of such a system by time-stepping methods and to the understanding
of the behavior of the system trajectory. Extending a previous result for a strongly regular differential variational inequality,
this paper establishes that a certain class of non-strongly regular differential variational inequalities is devoid of the
Zeno phenomenon. The proof involves many supplemental results that are of independent interest. Specialized to a frictional
contact problem with local compliance and polygonal friction laws, this non-Zenoness result is of fundamental significance
and the first of its kind.
