Spectral Theory of Infinite-Area Hyperbolic Surfaces (2nd ed.)

This text introduces geometric spectral theory in the context of infinite-area Riemann surfaces, providing a comprehensive account of the most recent developments in the field. For the second edition the context has been extended to general surfaces with hyperbolic ends, which provides a natural setting for development of the spectral theory while still keeping technical difficulties to a minimum.  All of the material from the first edition is included and updated, and new sections have bee
