Abstract :
We study systematical detection of the state variables for a quasi-static coupled circuit-field problem, which may consist of several disjoint domains for both field problems and electric networks. We translate the relevant questions about coupling into linear algebraic problems, i.e., use the homology theory. This enables us to express the state variable detection problem with readily programmable and computable concepts.
