An Atlantis-like city from Celtic legend is the setting of The Daughters of Ys, a mythical graphic novel fantasy from National Book Award winner M. T. Anderson and artist Jo Rioux. Ys, city of wealth and wonder, has a history of dark secrets. Queen Malgven used magic to raise the great walls that keep Ys safe from the tumultuous sea. But after the queen's inexplicable death, her daughters drift apart. Rozenn, the heir to the throne, spends her time on the moors communing with wild animals, while Dahut, the youngest, enjoys the splendors of royal life and is eager to take part in palace intrigue. When Rozenn and Dahut's bond is irrevocably changed, the fate of Ys is sealed, exposing the monsters that lurk in plain view. M. T. Anderson and Jo Rioux reimagine this classic Breton folktale of love, loss, and rebirth, revealing the secrets that lie beneath the surface.

Symmetry: An Introduction to Group Theory and its Application is an eight-chapter text that covers the fundamental bases, the development of the theoretical and experimental aspects of the group theory. Chapter 1 deals with the elementary concepts and definitions, while Chapter 2 provides the necessary theory of vector spaces. Chapters 3 and 4 are devoted to an opportunity of actually working with groups and representations until the ideas already introduced are fully assimilated. Chapter 5 looks into the more formal theory of irreducible representations, while Chapter 6 is concerned largely with quadratic forms, illustrated by applications to crystal properties and to molecular vibrations. Chapter 7 surveys the symmetry properties of functions, with special emphasis on the eigenvalue equation in quantum mechanics. Chapter 8 covers more advanced applications, including the detailed analysis of tensor properties and tensor operators. This book is of great value to mathematicians, and math teachers and students.

High-level text applies group theory to physics problems, develops methods for solving molecular vibration problems and for determining the form of crystal tensors, develops translational properties of crystals, more. 1974 edition.

This book is intended to provide an adequate background for various theortical physics courses, especially those in classical mechanics, electrodynamics, quatum mechanics and statistical physics. Each topic is dealt with in a generally self-contained manner and the text is interspersed with a number of solved examples ad a large number of exercise problems.
