Well-posedness and exponential stability for abstract evolution equations with delay in the nonlinear source: frictional and viscoelastic cases
Houria Chellaoua, Yamna Boukhatem, Cristina Pignotti
In this paper, we establish the well-posedness and exponential stability of a class of semilinear neutral abstract evolution equations with constant time delay. Two damping mechani…

Consensus and flocking with transmission and reaction delays
Elisa Continelli, Jan Haskovec, Cristina Pignotti
We investigate consensus formation and flocking behavior in multi-agent systems subject to two distinct types of delays: a transmission delay accounting for information exchange be…
