Circuit Duality and the General Network Inverse
G.E. Sharpe, George P. H. Styan · IEEE Transactions on Circuit Theory · 1965
An n-terminal electrical network is specified by a double-centered equicofactor admittance matrix, which represents the current vector as a rankn - 1linear transformation of the voltage vector. Several dual impedance descriptions are given in terms of baseset matrices and generalized inverses. The main result is the introduction of a unique general network inverse.
