State spaces of JB * -triples *

open access: yesMathematische Annalen, 2004
An atomic decomposition is proved for Banach spaces which satisfy some affine geometric axioms compatible with notions from the quantum mechanical measuring process. This is then applied to yield, under appropriate assumptions, geometric characterizations, up to isometry, of the unit ball of the dual space of a JB*-triple, and up to complete isometry ...

Distributed State Space Minimization

open access: yesElectronic Notes in Theoretical Computer Science, 2003
AbstractIn [5], we have given a straightforward distributed implementation of the Kanellakis-Smolka 'naive' algorithm for reducing labeled transition systems modulo strong bisimulation. The algorithm proceeds by partition refinement, that is by computing increasingly fine-grained partitions of the set of states.

Large State Space Visualization [PDF]

open access: yes, 2003
Insight in the global structure of a state space is of great help in the analysis of the underlying process. We present a tool to visualize the structure of very large state spaces. It uses a clustering method to obtain a simplified representation, which is used as a backbone for the display of the entire state space.
