The hunt puts him on the trail of an apocalyptic power that will force Asakawa to choose between saving his family and saving civilization.

The theory of algebras, rings, and modules is one of the fundamental domains of modern mathematics. General algebra, more specifically non-commutative algebra, is poised for major advances in the twenty-first century (together with and in interaction with combinatorics), just as topology, analysis, and probability experienced in the twentieth century. This is the second volume of Algebras, Rings and Modules: Non-commutative Algebras and Rings by M. Hazewinkel and N. Gubarenis, a continuation stressing the more important recent results on advanced topics of the structural theory of associative algebras, rings and modules.

Stunning Japanese novel with a chilling twist – the follow-up to Ring and Spiral.

THE GLOBE AND MAIL BEST BOOKS OF 2021 CBC BOOKS THE BEST CANADIAN FICTION OF 2021 A fresh take on the romance novel from the Giller Prize–winning author of Fifteen Dogs From their first meeting, it was clear that Gwen and Tancred were meant to be together. But, as we know, the course of true love never did run smooth. Gwen’s mother, intuiting that her daughter is in love, gives her a magic ring that has been passed down through endless generations of mothers and daughters. This ring grants its wearer the opportunity to change three things about her beloved. Like all blessings, this may also be a curse. Ring turns the literary romance upside down and shakes out its pockets. It’s a playful meditation on the past, on magic, on race, on honour, on faith, and, yes, on love. Following on the heels of Pastoral, Fifteen Dogs, The Hidden Keys, and Days by Moonlight, Ring completes Alexis’s Quincunx, a group of five genre-bending, philosophically sophisticated, and utterly delightful novels. “A great novel doesn’t try to answer questions, but, like Days by Moonlight, complicates them. ” —The Globe and Mail on Days by Moonlight “This imaginative travelogue will amuse readers even as it raises weightier issues. ” —Publishers Weekly on Days by Moonlight “I’m far from being a dog person, but as a book person I loved this smart, exuberant fantasy from start to finish. ” —The Guardian on Fifteen Dogs “A clever exploration of our essence, communication, and how our societies are organized. ” —Kirkus Reviews on Fifteen Dogs "Ring raises questions about love, marriage, fidelity, and the divine." —Canadian Writers Abroad

This book gives an overview of research on graphs associated with commutative rings. The study of the connections between algebraic structures and certain graphs, especially finite groups and their Cayley graphs, is a classical subject which has attracted a lot of interest. More recently, attention has focused on graphs constructed from commutative rings, a field of study which has generated an extensive amount of research over the last three decades. The aim of this text is to consolidate this large body of work into a single volume, with the intention of encouraging interdisciplinary research between algebraists and graph theorists, using the tools of one subject to solve the problems of the other. The topics covered include the graphical and topological properties of zero-divisor graphs, total graphs and their transformations, and other graphs associated with rings. The book will be of interest to researchers in commutative algebra and graph theory and anyone interested in learning about the connections between these two subjects.
