We developed a cyclic coefficient (R) to measure circulation in complex networks. Higher R values indicate more cyclic structures, unlike treelike networks where R is zero.

Area of Science:

  • Network Science
  • Graph Theory
  • Complex Systems Analysis

Background:

  • Understanding the structural properties of complex networks is crucial.
  • Quantifying cyclic patterns within networks is an ongoing challenge.
  • Existing network metrics may not fully capture the degree of circulation.

Purpose of the Study:

  • To introduce a novel metric, the cyclic coefficient (R), for quantifying circulation in complex networks.
  • To establish a relationship between the cyclic coefficient and the presence of treelike structures.
  • To analyze and compare the cyclic structures of various real-world networks.

Main Methods:

  • Definition and derivation of the cyclic coefficient (R).
  • Calculation of global cyclic coefficients for diverse network types.

  • Analysis of the distributions of local cyclic coefficients within networks.

    • Main Results:

    • The cyclic coefficient (R) accurately distinguishes treelike structures (R=0) from cyclic ones.
    • Networks with higher R values exhibit more pronounced cyclic characteristics.
    • The distribution of local cyclic coefficients provides insights into the heterogeneity of cyclic structures.

    Conclusions:

    • The cyclic coefficient (R) offers a robust measure of network circulation.
    • This metric enhances the characterization of complex network topologies.
    • Further applications of R can illuminate the functional implications of cyclic structures in various systems.
