That is, given a correlation function f reflecting the desire for each pair of elements to be near each other, find all permutations π with the property that if π(i) < π(j) < π(k) then f(i, j) ≥ f(i, k) and f(j, k) ≥ f(i, k). About these proceedings. In applications ranging from DNA sequencing through archeological dating to sparse matrix reordering, a recurrent problem is the sequencing of elements in such a way that highly correlated pairs of elements are near each other.

Important applications of graph spectra involve the largest or second largest or smallest eigen-value, or interlacing, topics that are discussed in Chapters 3–4. The theory of graph spectra can, in a way, be considered as an attempt to utilize linear algebra including, in particular, the well-developed theory of matrices for the purposes of graph theory and its applications. Sorted by: Results 1 - 10 of 23. It is the aim of this survey paper to explain where this belief comes from. The D-eigenvalues of a graph G are the eigenvalues of its distance matrix D, and the D-energy ED(G) is the sum of the absolute values of its D-eigenvalues. We first characterize the exact conditions on the geometry of the peer network, so that the model is fully identified.

Many challenges remain to be addressed in scaling the proposed framework to large MDPs, and several elaboration of the proposed framework are briefly summarized at the end. ISBN-10: 3527296859. Spectra and Quantum Transport on Graphs, Graph Theory - Advanced Algorithms and Applications, Beril Sirmacek, IntechOpen, DOI: 10.5772/intechopen.68480. 931 15

They have also become a theoretician's friend in analyzing the mixing times of random walks in graphs, the study of expanders and pseudo-randomness, and graph partitioning. Google Scholar; 13. The paper is essentially a survey of known results about the spectrum of the Laplacian matrix of graphs with special emphasis on the second smallest Laplacian eigenvalue λ 2 and its relation to numerous graph invariants, including connectivity, expanding properties, isoperimetric number, ...".

We show here that this matrix function can be derived from physical models that consider the interactions between nearest and next-nearest neighbors in the graph. Pairs of equiregular D-equienergetic graphs of diameter 2, on p = 3t+ 1 vertices are also constructed. 0000006976 00000 n
Some new results and generalizations are added. Spectra Techniques in Graph Theory and Combinatories. That is, given a correlation function f reflecting the desire for each pair of elements to be near each other, find all permutations π with the property that if π(i) < π(j) < π(k) then f(i, j) ≥ f(i, k) and f(j, k) ≥ f(i, k). About these proceedings. In applications ranging from DNA sequencing through archeological dating to sparse matrix reordering, a recurrent problem is the sequencing of elements in such a way that highly correlated pairs of elements are near each other. The theory of graph spectra can, in a way, be considered as an attempt to utilize linear algebra including, in particular, the well-developed theory of matrices for the purposes of graph theory and its applications.
