We study 't Hooft anomalies and the related anomaly inflow for subsystem global symmetries. These symmetries arise in a number of exotic systems, including models with fracton order such as X-cube model. As is case ordinary symmetries, can be canceled by from bulk theory one higher dimension; corresponding therefore non-trivial symmetry protected topological (SSPT) phase. demonstrate these phen...

A max-plus system with partial synchronization is a persistent discrete event system divided into a main subsystem and a secondary subsystem such that the secondary subsystem has to adjust its behavior to the main subsystem, but the main subsystem is not affected by the secondary subsystem. A formal model based on max-plus recursive equations is presented for max-plus systems with partial synch...
