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 been added. Topics covered include an introduction to the geometry of hyperbolic surfaces, analysis of the resolvent of the Laplacian, scattering theory, resonances and scattering poles, the Selberg zeta funct...
Walking, Landscape and Environment explores walking as a method of research and practice in the humanities and creative arts, emerging from a recent surge of growth in urban and rural walking. This edited collection of essays from leading figures in the field presents an enquiry into, and a critique of, the methods and results of cutting-edge ‘walking research’. Walking negotiates the intersections between the human self, place and space, offering a cross-disciplinary collaborative method of research which can be utilised in areas such as ecocriticism, landscape architecture, literature, cultural geography and the visual arts. Bringing together a multitude of perspectives from different disciplines, on topics including health and wellbeing, disability studies, social justice, ecology and gender, this book provides a unique appraisal of the humanist perspective on landscape. In doing so, it challenges Romantic approaches to walking, applying new ideas in contemporary critical thought and alternative perspectives on embodiment and trans-corporeality.
This modern take on partial differential equations does not require knowledge beyond vector calculus and linear algebra. The author focuses on the most important classical partial differential equations, including conservation equations and their characteristics, the wave equation, the heat equation, function spaces, and Fourier series, drawing on tools from analysis only as they arise. Within each section the author creates a narrative that answers the five questions: What is the scientific problem we are trying to understand? How do we model that with PDE? What techniques can we use to analyze the PDE? How do those techniques apply to this equation? What information or insight did we obtain by developing and analyzing the PDE? The text stresses the interplay between modeling and mathematical analysis, providing a thorough source of problems and an inspiration for the development of methods.

This textbook offers a concise introduction to spectral theory, designed for newcomers to functional analysis. Curating the content carefully, the author builds to a proof of the spectral theorem in the early part of the book. Subsequent chapters illustrate a variety of application areas, exploring key examples in detail. Readers looking to delve further into specialized topics will find ample references to classic and recent literature. Beginning with a brief introduction to functional analysis, the text focuses on unbounded operators and separable Hilbert spaces as the essential tools needed for the subsequent theory. A thorough discussion of the concepts of spectrum and resolvent follows,...
