A time-varying expectations formation mechanism [PDF]
Economia Politica, 2019 We propose an expectations formation mechanism (EFM) aimed to explain the median—hence lay—forecaster’s year-ahead inflation predictions. The EFM is a time-varying combination of long-run expectations, current inflation and uncertainty with weights naively calibrated according to inflation dynamics.

Time-varying formation control of multiple quad-rotors based on ellipsoid
International Journal of Advanced Robotic Systems, 2021 Time-varying formation control problem for a group of multiple quad-rotors has been considered in this article with the help of ellipsoid. Firstly, an elliptic equation with time-varying parameters has been firstly introduced to describe the desired ...

Formation Control of Second‐Order Multiagent Systems with Time‐Varying Delays [PDF]
Mathematical Problems in Engineering, 2014 A formation control problem for second‐order multiagent systems with time‐varying delays is considered. First, a leader‐following consensus protocol is proposed for theoretical preparation. With the help of Lyapunov‐Krasovskii functional, a sufficient condition under this protocol is derived for stability of the multiagent systems.

IEEE Access, 2021 This paper studies the formation control problem of discrete-time multi-agent systems with noisy information in time-varying communication networks. To achieve the desired formation, a control law with a decaying-gain is designed.

Controllable plasma energy bands in a 1D crystal of fractional Josephson vortices [PDF]
, 2004 We consider a 1D chain of fractional vortices in a long Josephson junction with alternating $\pm\kappa$ phase discontinuities. Since each vortex has its own eigenfrequency, the inter-vortex coupling results in eigenmode splitting and in the formation of ...

Theory of synchronisation and pattern formation on time varying networks [PDF]
Chaos, Solitons & Fractals, 2022 Synchronisation and pattern formation have been intensely addressed for systems evolving on static networks. Extending the study to include the inherent ability of the network to adjust over time proved cumbersome and led to conclusions which lack of generality, as relying on peculiar assumptions.
