Book Description
The unnamed narrator of "Metaphysica Morum" seeks suicide, yet delays until he can subvert the optimism of his fugitive therapist. Equally anonymous, the young narrator of "The Small People" finds a growing horror in the encroachment of toy-like beings that bring an unsettling enlightenment about the shabbiness of daily life and the true nature of his parents

Book Description
The intention of this book is to introduce students to active areas of research in mathematical physics in a rather direct way minimizing the use of abstract mathematics. The main features are geometric methods in spectral analysis, exponential decay of eigenfunctions, semi-classical analysis of bound state problems, and semi-classical analysis of resonance. A new geometric point of view along with new techniques are brought out in this book which have both been discovered within the past decade. This book is designed to be used as a textbook, unlike the competitors which are either too fundamental in their approach or are too abstract in nature to be considered as texts. The authors' text fills a gap in the marketplace.

Book Description
Along with finite differences and finite elements, spectral methods are one of the three main methodologies for solving partial differential equations on computers. This book provides a detailed presentation of basic spectral algorithms, as well as a systematical presentation of basic convergence theory and error analysis for spectral methods. Readers of this book will be exposed to a unified framework for designing and analyzing spectral algorithms for a variety of problems, including in particular high-order differential equations and problems in unbounded domains. The book contains a large number of figures which are designed to illustrate various concepts stressed in the book. A set of basic matlab codes has been made available online to help the readers to develop their own spectral codes for their specific applications.

Book Description
This book presents the basic tools of modern analysis within the context of the fundamental problem of operator theory: to calculate spectra of specific operators on infinite dimensional spaces, especially operators on Hilbert spaces. The tools are diverse, and they provide the basis for more refined methods that allow one to approach problems that go well beyond the computation of spectra: the mathematical foundations of quantum physics, noncommutative K-theory, and the classification of simple C*-algebras being three areas of current research activity which require mastery of the material presented here.

Book Description
Theater’s materiality and reliance on human actors has traditionally put it at odds with modernist principles of aesthetic autonomy and depersonalization. Spectral Characters argues that modern dramatists in fact emphasized the extent to which humans are fictional, made and changed by costumes, settings, props, and spoken dialogue. Examining work by Ibsen, Wilde, Strindberg, Genet, Kopit, and Beckett, the book takes up the apparent deadness of characters whose selves are made of other people, whose thoughts become exteriorized communication technologies, and whose bodies merge with walls and furniture. The ghostly, vampiric, and telepathic qualities of these characters, Sarah Balkin argues, mark a new relationship between the material and the imaginary in modern theater. By considering characters whose bodies respond to language, whose attempts to realize their individuality collapse into inanimacy, and who sometimes don’t appear at all, the book posits a new genealogy of modernist drama that emphasizes its continuities with nineteenth-century melodrama and realism.

Book Description
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, leading to a complete proof of the spectral theorem for unbounded self-adjoint operators. Applications of spectral theory to differential operators comprise the remaining four chapters. These chapters introduce the Dirichlet Laplacian operator, Schrödinger operators, operators on graphs, and the spectral theory of Riemannian manifolds. Spectral Theory offers a uniquely accessible introduction to ideas that invite further study in any number of different directions. A background in real and complex analysis is assumed; the author presents the requisite tools from functional analysis within the text. This introductory treatment would suit a functional analysis course intended as a pathway to linear PDE theory. Independent later chapters allow for flexibility in selecting applications to suit specific interests within a one-semester course.

Book Description
Visitors to the Arctic enter places that have been traditionally imagined as otherworldly. This strangeness fascinated audiences in nineteenth-century Britain when the idea of the heroic explorer voyaging through unmapped zones reached its zenith. The Spectral Arctic re-thinks our understanding of Arctic exploration by paying attention to the importance of dreams and ghosts in the quest for the Northwest Passage. The narratives of Arctic exploration that we are all familiar with today are just the tip of the iceberg: they disguise a great mass of mysterious and dimly lit stories beneath the surface. In contrast to oft-told tales of heroism and disaster, this book reveals the hidden stories of dreaming and haunted explorers, of frozen mummies, of rescue balloons, visits to Inuit shamans, and of the entranced female clairvoyants who travelled to the Arctic in search of John Franklin’s lost expedition. Through new readings of archival documents, exploration narratives, and fictional texts, these spectral stories reflect the complex ways that men and women actually thought about the far North in the past. This revisionist historical account allows us to make sense of current cultural and political concerns in the Canadian Arctic about the location of Franklin’s ships.

Book Description
Graph spectral image processing is the study of imaging data from a graph frequency perspective. Modern image sensors capture a wide range of visual data including high spatial resolution/high bit-depth 2D images and videos, hyperspectral images, light field images and 3D point clouds. The field of graph signal processing – extending traditional Fourier analysis tools such as transforms and wavelets to handle data on irregular graph kernels – provides new flexible computational tools to analyze and process these varied types of imaging data. Recent methods combine graph signal processing ideas with deep neural network architectures for enhanced performances, with robustness and smaller memory requirements. The book is divided into two parts. The first is centered on the fundamentals of graph signal processing theories, including graph filtering, graph learning and graph neural networks. The second part details several imaging applications using graph signal processing tools, including image and video compression, 3D image compression, image restoration, point cloud processing, image segmentation and image classification, as well as the use of graph neural networks for image processing.
