Continuing in this manner, the set of all positive integers is partitioned into sets S i , which are themselves partitioned into sets of recurrence sequences. Next, arrange
The set of spectrally arbitrary sign patterns is a subset of the set of potentially stable sign patterns, and for tree sign patterns of order 4, the set of all potentially stable
We show that our construction yields all Leonard pairs of Racah, Hahn, dual Hahn, and Krawtchouk type, and no other types of Leonard pairs..
Research on multidimensional scaling continues to exploit facts about distance matrices, e.g., [10].. Analogously, in com- putational chemistry and structural molecular biology,
The path, the complete graph, the cycle, the star and some quasi-star graphs, together with their complement graphs were shown to be determined by their Laplacian spectra [6, 9,
An open path in the oriented percolation is a finite alternating sequence e i , v i of edges and vertices, all of which are “open” (that is, the attached Bernoulli random variables
