Twisted isospectrality, homological wideness, and isometry : a sample of algebraic methods in isospectrality

Twisted isospectrality, homological wideness, and isometry : a sample of algebraic methods in isospectrality / Gunther Cornelissen, Norbert Peyerimhoff.

The question of reconstructing a geometric shape from spectra of operators (such as the Laplace operator) is decades old and an active area of research in mathematics and mathematical physics. This book focusses on the case of compact Riemannian manifolds, and, in particular, the question whether on...
