Graph theory and molecular orbitals. The loop rule

Chemical Physics Letters, 1973
Abstract Graph theory is applied to the study of the dependence of total π-electron energy, π-electron charge distribution and free valency indices of conjugated hydrocarbons on molecular topology. It is shown that the number of loops in the molecular graph determines these quantities.

A Graph Theory Approach to Demographic Loop Analysis

Ecology, 1998
A demographic analysis of the life-cycle graph can be used to quantify the separate contributions of different life-history types to the population growth rate. Loop analysis has been proposed (van Groenendael et al. 1994) as the appropriate method for partitioning the elasticity matrix to determine these contributions.

On elementary theories of graphs and Abelian loops

Mathematical Notes of the Academy of Sciences of the USSR, 1974
The algorithmic decidability of elementary theories of certain classes of graphs, such as homogeneous, planar, bipartite planar, and critical nonplanar, is discussed. For the first three classes we prove the undecidability of elementary theories, and for the last, decidability with a supplementary predicate.

On the evaluation of ultra-high-precision frequency ratio measurements: examining closed loops in a graph theory framework

Metrologia, 2016
A simple method is proposed for the evaluation of comparative measurements when closed measurement loops are present in the data. Using a graph theory representation of the data a basis for the residual subspace is readily identified that together with loop closure values provide the input to a matrix equation of the same rank as the number of ...

A step-by-step method for Z-loop construction using graph theory and topology for power system studies

2008 IEEE Region 8 International Conference on Computational Technologies in Electrical and Electronics Engineering, 2008
This manuscript will provide a step by step method on how a graph theory and topology can be utilized to construct a Z-loop matrix for the study of faulted power systems. The growing demand for reliable electrical power supply has forced the pace developments in electrical power system analysis using computer.
