David L Powers(
Book
)
40 editions published between 2005 and 2010 in English and Undetermined and held by 285 WorldCat member libraries worldwide
"Boundary Value Problems is the leading text on boundary value problems and Fourier series for professionals and students in engineering, science, and mathematics who work with partial differential equations. In this update classic, author David Powers provides a thorough overview of solving boundary value problems involving partial differential equations by separation of variables. Additional techniques used include Laplace transform and numerical methods. This edition offers a thorough treatment of one dimensional models before introducing more complicated problems."Jacket

Graph Partitioning by Eigenvectors(
Book
)
1 edition published in 1987 in English and held by 1 WorldCat member library worldwide
Let A be the adjacency matrix of a connected graph G. If z is a column vector, we say that a vertex of G is positive, nonnegative, null, etc. if the corresponding entry of z has that property. For z such that Az> or = alpha z, we bound the number of components in the subgraph induced by positive vertices. For eigenvectors z having a null element, we bound the number of components in the graph induced by nonnull vertices. Finally, bounds are established for the number of null elements in an eigenvector, for the multiplicity of an eigenvalue and for the magnitudes of the second and last eignevalues of a general or a bipartite graph

The objective of this work is to find properties of a distanceregular graph G that are expressed in the eigenvectors of its adjacency matrix. The approach is to consider the rows of a matrix of orthogonal eigencolumns as (coordinates of) points in euclidean space, each one corresponding to a vertex of G. For the second eigenvalue, the symmetry group of the points is isomorphic to the automorphism group of G. Adjacency of vertices is related to linear dependence, linear independence and proximity of points. Relative position of points studied by way of the polytope that is their convex hull. Several families of examples are included
