A signed graph is the special kind of gain graph in which the gain group has order 2. The pair (G, B(Σ)) determined by a signed graph Σ is a special kind of biased graph. The sign group has the special property, not shared by larger gain groups, that the edge signs are determined up to switching by the set B(Σ) of balanced cycles. [19]
Children's shoes start from size zero, which is equivalent to 3 + 11 ⁄ 12 inches (11 + 3 ⁄ 4 barleycorns = 99.48 mm), and end at 13 + 1 ⁄ 2. Thus the formula for children's sizes in the US is child shoe size (barleycorns) = 3 × last length (in) − 11 3 ⁄ 4. equivalent to: child shoe size (barleycorns) ≈ 3 × foot length (in) − 9 3 ...
By definition, a trace diagram's function is computed using signed graph coloring. For each edge coloring of the graph's edges by n labels, so that no two edges adjacent to the same vertex have the same label, one assigns a weight based on the labels at the vertices and the labels adjacent to the matrix labels. These weights become the ...
A pair of graphs are said to be cospectral mates if they have the same spectrum, but are non-isomorphic. The smallest pair of cospectral mates is {K 1,4, C 4 ∪ K 1}, comprising the 5-vertex star and the graph union of the 4-vertex cycle and the single-vertex graph [1]. The first example of cospectral graphs was reported by Collatz and ...
Spectral graph theory relates properties of a graph to a spectrum, i.e., eigenvalues, and eigenvectors of matrices associated with the graph, such as its adjacency matrix or Laplacian matrix. Imbalanced weights may undesirably affect the matrix spectrum, leading to the need of normalization — a column/row scaling of the matrix entries ...
BS 3666:1982 Specification for size designation of women's wear BS 6185:1982 Specification for size designation of men's wear BS 3666:1982, the standard for women's clothing, is rarely followed by manufacturers as it defines sizes in terms of hip and bust measurements only within a limited range.

Analogously to the classical Fourier transform, the eigenvalues represent frequencies and eigenvectors form what is known as a graph Fourier basis. The Graph Fourier transform is important in spectral graph theory. It is widely applied in the recent study of graph structured learning algorithms, such as the widely employed convolutional networks.
