A Necessary Condition for Dynamic Equivalence [PDF]

open access: yesSIAM Journal on Control and Optimization, 2009
If two control systems on manifolds of the same dimension are dynamic equivalent, we prove that either they are static equivalent, i.e., equivalent via a classical diffeomorphism, or they are both ruled; for systems of different dimensions, the one of higher dimension must be ruled.

Regular Equivalence and Dynamic Logic

Social Networks, 2003
Abstract This paper describes a precise linguistic counterpart to the notion of a regular equivalence relation on a social network. That is, a formal language of position terms is defined with the property that on finite networks, two actors are regularly equivalent if and only if they cannot be distinguished by a position term.
