Phase retrieval for nilpotent groups
This talk presents new results on phase retrieval for group representations. Precisely, we show that the (unitary) irreducible representations of nilpotent groups (finite and infinite) allow phase retrieval. This is joint work with Hartmut Fuehr.

Resource-Aware Control and Coordination of Cyberphysical Systems
Trading computation and decision making for less communication, sensing, or actuator effort offers great promise for the autonomous operation of both individual and interconnected cyberphysical systems. Resource-aware control seeks to prescribe, in a principled way, when to use the available resources efficiently while still guaranteeing a desired quality of service in performing the intended task. This talk describes advances of this paradigm along three interconnected thrusts: the design of triggering criteria that balance the trade-offs among performance, efficiency, and implementability; the synthesis of distributed triggers in network systems that can be evaluated by individual agents; and the benefits of flexibly interpreting what constitutes a resource. Throughout the presentation, we illustrate our discussion with applications to stabilization under information constraints, opportunistic actuation of safety-critical systems, and information exchanges in the coordination of multi-agent systems.
