First and second-order Cucker-Smale models with non-universal interaction, time delay and communication failures
Chiara Cicolani, Elisa Continelli, Cristina Pignotti
In this paper, we deal with first and second-order alignment models with non-universal interaction, time delay and possible lack of connection between the agents. More precisely, w…
Energy decay for semilinear evolution equations with memory and time-dependent time delay feedback
Elisa Continelli, Cristina Pignotti
In this paper, we study well-posedness and exponential stability for semilinear second order evolution equations with memory and time-varying delay feedback. The time delay functio…
Opinion dynamics of two populations with time-delayed coupling
Chiara Cicolani, Cristina Pignotti
We study a Hegselmann-Krause type opinion formation model for a system of two populations. The two groups interact with each other via subsets of individuals, namely the leaders, a…
Exponential decay of solutions to linear evolution equations with time-dependent time delay
Elisa Continelli, Cristina Pignotti
In this note, we analyze an abstract evolution equation with time-dependent time delay and time-dependent delay feedback coefficient. We assume that the operator corresponding to t…
Stability for some classes of degenerate nonlinear hyperbolic equations with time delay
Alessandro Camasta, Genni Fragnelli, Cristina Pignotti
We consider several classes of degenerate hyperbolic equations involving delay terms and suitable nonlinearities. The idea is to rewrite the problems in an abstract way and, using…
