Abstract:The resistance between two arbitrary nodes of a network of resistors is studied when the network is perturbed by connecting an extra resistor between two arbitrary nodes in the perfect lattice. The lattice Green's function and the resistance of the perturbed network are expressed in terms of those of the perfect lattice by solving Dyson's equation. A comparison is carried out between numerical and experimental results for a square lattice.
“…A classic problem in electric circuit theory studied by numerous authors over 160 years is the computation of the resistance between two nodes in a resistor network , yet some basic problem in m × n cobweb network is still not solved ideally .

“…This structure of m × n cobweb model determines its meaning of owning many potential applications. Although the researchers have made brilliant achievements in the field of rectangular network, the research for the cobweb network has only just begun not only in results but also in methods. In addition, there have been very few studies on the impedance between two arbitrary nodes in an m × n RLC cobweb network.…”

SUMMARYA basic theorem of equivalent resistance between two arbitrary nodes in an m × n cobweb network in both finite and infinite conditions is discovered, and two conjectures on the equivalent resistance are proved in terms of the basic theorem. We built a tridiagonal matrix equation by means of network analysis and made a diagonalization method of matrix transformation and work out its explicit expressions. The new formulae obtained here can be effectively applied in complex impedance network, especially the formulation leads to the occurrence of resonances and a series of novel results in RLC (denote resistor, inductance and capacitance) network. These curious results suggest the possibility of practical applications to resonant circuits.

“…18 Based on this approach, several interesting applications were presented. [9][10][11][12][13][14][15][16][17][18] The problem of computing the two-node resistance on finite resistor networks was considered by Wu. 19 He obtained a general expression for the resistance of a finite resistor graph in terms of the eigenvalues and the eigenvectors of the Kirchhoff matrix.…”
The effective resistance between any pair of vertices (sites) on the three-dimensional decorated centered cubic lattices is determined by using lattice Green's function method. Numerical results are presented for infinite decorated centered cubic networks. A mapping between the resistance of the edge-centered cubic lattice and that of the simple cubic lattice is shown
SUMMARYA classic problem in electric circuit theory studied by numerous authors over 160 years is the computation of the resistance between two nodes in a resistor network, yet some basic problem in m  n cobweb network is still not solved ideally. The equivalent resistance and capacitance of 4  n cobweb network are investigated in this paper. We built a quaternion matrix equation and proposed the method of matrix transformations in terms of the network analysis. We proposed a brief equivalent resistance formula and find that the equivalent resistance is expressed by cos(kπ/9) in a series of strict calculation. Meanwhile, an equivalent resistance of infinite networks is gained. Using the inverse mapping relation between capacitance parameters and resistance parameters, the equivalent capacitance formula is also given for the 4  n capacitance cobweb network. By analyzing and comparing the equivalent resistances of the 1  n, 2  n, 3  n and 4  n cobweb networks, two conjectures on the equivalent resistance and capacitance of the m  n cobweb network are proposed.
