Agency in Natural and Artificial Systems
We analyze the conditions for agency in natural and artificial systems. In the case of basic (natural) autonomous systems, self-construction and activity in the environment are two...

State Aggregation and Population Dynamics in Linear Systems
We consider complex systems that are composed of many interacting elements, evolving under some dynamics. We are interested in characterizing the ways in which these elements may b...

Levels of Description: A Novel Approach to Dynamical Hierarchies
We present a novel formal interpretation of dynamical hierarchies based on information theory, in which each level is a near-state-determined system, and levels are related to one ...
