Detailed Description

Tutorial, verification of properties of natural projections.

This tutorial explains the routines for verifying if the Lm-observer condition, output control consistency (OCC) or local control consistency (LCC) are fulfilled for a given natural projection. The computations are carried out with a given generator and a given high-level alphabet.

    or local control consistency (LCC) are fulfilled for a given natural projection. The computations are carried out
