DECOMPOSITION THEOREM AND k-HYPERCONNECTION EXPRESSIONS FOR GENERAL k-ORDER COFACTORS
一般k阶余因式的k超连接表达式和分解定理

Two k-hyperconnection expressions of a general k-order cofactor Y(ij) are presented for the indefinite parameter matrix Y of a linear system, and based on it, a decom-position theorem of Y (ij) is dcrived. By this theorem, the multi-level tearing and analysis can be carried out easily for any large linear system. This is a new multi-level topological analysis method. Using the method the scale of systems which can be topologically analysed by a computer will be increased.
