Abstract
We consider stability and bifurcation on a finite time interval in a thermoviscoelastoplastic contact problem posed in the form of a variational system depending on a parameter. To describe stability and bifurcation, the latter being understood as stability loss on a finite time interval, we use the frequency-domain approach. We present frequency-domain conditions for the existence of determining observations and the absolute dichotomy of the variational equation.
