This compelling LBGTQ novel by LAMBDA award-winning author Watts explores the unlikely friendship between Libby, the oldest child in a rural Tennessee family of strict evangelical Christians, and Zo, her gender fluid new neighbor.

Kate McCall's husband has been killed by her teenage son, Luke, in a tragic bow-hunting accident. In the aftermath, Jack, a charismatic but troubled ex-con from Kate's past, shows up. When Luke takes off on his own for their rural Michigan cabin, Kate and Jack follow, but they're not the only ones hot on his heels. Two-time losers Teddy and Celeste, along with hitman DeJuan, are all looking to cash in on the money left to Kate. As they all head for the woods of Northern Michigan, events rapidly spiral towards a dramatic life-and-death confrontation. Filled with unforgettable characters, razor-sharp dialogue and masterful plotting, Quiver displays the remarkable maturity and verve of a hugely exciting first-time novelist.

This book is an introduction to the representation theory of quivers and finite dimensional algebras. It gives a thorough and modern treatment of the algebraic approach based on Auslander-Reiten theory as well as the approach based on geometric invariant theory. The material in the opening chapters is developed starting slowly with topics such as homological algebra, Morita equivalence, and Gabriel's theorem. Next, the book presents Auslander-Reiten theory, including almost split sequences and the Auslander-Reiten transform, and gives a proof of Kac's generalization of Gabriel's theorem. Once this basic material is established, the book goes on with developing the geometric invariant theory of quiver representations. The book features the exposition of the saturation theorem for semi-invariants of quiver representations and its application to Littlewood-Richardson coefficients. In the final chapters, the book exposes tilting modules, exceptional sequences and a connection to cluster categories. The book is suitable for a graduate course in quiver representations and has numerous exercises and examples throughout the text. The book will also be of use to experts in such areas as representation theory, invariant theory and algebraic geometry, who want to learn about applications of quiver representations to their fields.

A collection of stories focusing on the spontaneous erotic experiences of a small group of middle-class acquaintances, from the heterosexual to the bisexual, and from the exhibitionistic to the sadomasochistic.

This book is intended to serve as a textbook for a course in Representation Theory of Algebras at the beginning graduate level. The text has two parts. In Part I, the theory is studied in an elementary way using quivers and their representations. This is a very hands-on approach and requires only basic knowledge of linear algebra. The main tool for describing the representation theory of a finite-dimensional algebra is its Auslander-Reiten quiver, and the text introduces these quivers as early as possible. Part II then uses the language of algebras and modules to build on the material developed before. The equivalence of the two approaches is proved in the text. The last chapter gives a proof of Gabriel’s Theorem. The language of category theory is developed along the way as needed.

Persistence theory emerged in the early 2000s as a new theory in the area of applied and computational topology. This book provides a broad and modern view of the subject, including its algebraic, topological, and algorithmic aspects. It also elaborates on applications in data analysis. The level of detail of the exposition has been set so as to keep a survey style, while providing sufficient insights into the proofs so the reader can understand the mechanisms at work. The book is organized into three parts. The first part is dedicated to the foundations of persistence and emphasizes its connection to quiver representation theory. The second part focuses on its connection to applications through a few selected topics. The third part provides perspectives for both the theory and its applications. The book can be used as a text for a course on applied topology or data analysis.
