The spectral geometry of infinite graphs deals with three major themes and their interplay: the spectral theory of the Laplacian, the geometry of the underlying graph, and the heat flow with its probabilistic aspects. In this book, all three themes are brought together coherentl…
This book gives a detailed and self-contained introduction into the theory of spectral functions, with an emphasis on their applications to quantum field theory. All methods are illustrated with applications to specific physical problems from the forefront of current research, s…
This work presents some classical as well as some very recent results and techniques concerning the spectral geometry corresponding to the Laplace-Beltrami operator and the Hodge-de Rham operators. It treats many topics that are not usually dealt with in this field.
It is known that to any Riemannian manifold (M, g), with or without boundary, one can associate certain fundamental objects. Among them are the Laplace-Beltrami operaƯ tor and the Hodge-de Rham operators, which are natural [that is, they commute with the isometries of (M, g)], e…
