A hypervirial perturbation method is shown to give accurate energy levels for a previously proposed Schrodinger Γ«quation for the relative motion of two ions in a Penning trap. The numerical results obtained by some previous authors are found to be in error and the new perturbation results are checke

A new method for analyzing the structure of a complex reaction network is proposed using a graph theoretical approach. The structural relation of chemical reactions and species in the network can be determined by a corresponding bipartite graph, and vice versa. Differential equations for the network
## In this paper we pursue the graph theoretic approach to the switching function minimization problem which is still important in view of today's technological innovations such as programmable Logic arrays. We use switching functions graphs (SFG) for studying the structure of switching functions an
