Let FG be the group ring of a group G over a field F. Write U(FG) for the group of units of FG. It is an important problem to determine the conditions under which U(FG) satisfies a group identity. In the mid 1990s, a conjecture of Hartley was verified, namely, if U(FG) satisfies a group identity, and G is torsion, then FG satisfies a polynomial identity. Necessary and sufficient conditions for U(FG) to satisfy a group identity soon followed. Since the late 1990s, many papers have been devoted to the study of the symmetric units; that is, those units u satisfying u* = u, where * is the involution on FG defined by sending each element of G to its inverse. The conditions under which these symmetric units satisfy a group identity have now been determined. This book presents these results for arbitrary group identities, as well as the conditions under which the unit group or the set of symmetric units satisfies several particular group identities of interest.
This carefully written textbook offers a thorough introduction to abstract algebra, covering the fundamentals of groups, rings and fields. The first two chapters present preliminary topics such as properties of the integers and equivalence relations. The author then explores the first major algebraic structure, the group, progressing as far as the Sylow theorems and the classification of finite abelian groups. An introduction to ring theory follows, leading to a discussion of fields and polynomials that includes sections on splitting fields and the construction of finite fields. The final part contains applications to public key cryptography as well as classical straightedge and compass constructions. Explaining key topics at a gentle pace, this book is aimed at undergraduate students. It assumes no prior knowledge of the subject and contains over 500 exercises, half of which have detailed solutions provided.
In the past decade, numerous military operations by outside states have relied on the real or alleged 'invitation' of one of the parties. In this book, three experts examine the relevant legal issues, from sovereignty to the scope and relevance of consent, the use of force to the role of the Security of Council. Using critical historical analysis, qualitative case studies and large-N empirics, these topics are debated and addressed in a unique trialogue format. Accommodating the pluralism of the field, the trialogical setting highlights the divergences and commonalities of each of the three approaches. Benefiting from an in-depth analysis of recent cases of armed intervention and the diversity of the authors' perspectives, this collection is key to developing a richer understanding of the law of military intervention. This title is also available as Open Access on Cambridge Core.
A dramatic tension confronts every Christian believer and interpreter of Scripture: on the one hand, we encounter images of God commanding and engaging in horrendous violence: one the other hand, we encounter the non-violent teachings and example of Jesus, whose loving, self-sacrificial death and resurrection is held up as the supreme revelation of God’s character in the New Testament. How do we reconcile the tension between these seemingly disparate depictions? Are they even capable of reconciliation? Throughout Christian history, many different answers have been proposed, ranging from the long-rejected explanation that these contrasting depictions are of two entirely different ‘gods’ to recent social and cultural theories of metaphor and narrative representation. The Crucifixion of the Warrior God takes up this dramatic tension and the range of proposed answers in an epic constructive investigation. Over two volumes, renowned theologian and biblical scholar Gregory A. Boyd argues that we must take seriously the full range of Scripture as inspired, including its violent depictions of God. At the same time, we must take just as seriously the absolute centrality of the crucified and risen Christ as the supreme revelation of God. Developing a theological interpretation of Scripture that he labels a “cruciform hermeneutic,” Boyd demonstrates how Scripture’s violent images of God are completely reframed and their violence subverted when they are interpreted through the lens of the cross and resurrection. Indeed, when read through this lens, Boyd argues that these violent depictions can be shown to bear witness to the same self-sacrificial character of God that was supremely revealed on the cross.

The shocking truth behind the death of an American icon—and the conspiracies that kept it secret for decades—in “the best autopsy of Marilyn Monroe” (Cyril H. Wecht, MD, JD) In her tragically short life, Marilyn Monroe embodied American womanhood, innocence, and lust—both as a Hollywood star and in the shadows of her tormented soul. But when she was found naked and dead on the morning of August 5, 1962, she became the subject of a mystery that has perplexed the world for generations. Was her death an accident? Suicide? Or murder? In Crypt 33, two Los Angeles private investigators recount the startling evidence that may solve the case once and for all, finally revealing the truth about: Monroe’s affairs with JFK and Robert Kennedy . . . The identity of the friend who allowed Monroe’s killers into her home . . . Evidence of the deadly drugs and how they were administered to the starlet . . . The rumors of an assassination plot masterminded by the Cosa Nostra and high-ranking government officials . . . The tangled web of wiretaps in Monroe’s home—and what happened to the audio tape recording of her murder . . . Now, at last, the truth of Monroe’s shocking death can be told in a book that “makes the hardest case yet that Marilyn was the victim of foul play” (Kirkus Reviews). “Well and sympathetically told . . . Speriglio and Gregory are fluent, convincing writers.” —Publishers Weekly
Works of fiction are works of the imagination and for the imagination. Gregory Currie energetically defends the familiar idea that fictions are guides to the imagination, a view which has come under attack in recent years. Responding to a number of challenges to this standpoint, he argues that within the domain of the imagination there lies a number of distinct and not well-recognized capacities which make the connection between fiction and imagination work. Currie then considers the question of whether in guiding the imagination fictions may also guide our beliefs, our outlook, and our habits in directions of learning. It is widely held that fictions very often provide opportunities for the acquisition of knowledge and of skills. Without denying that this sometimes happens, this book explores the difficulties and dangers of too optimistic a picture of learning from fiction. It is easy to exaggerate the connection between fiction and learning, to ignore countervailing tendencies in fiction to create error and ignorance, and to suppose that claims about learning from fiction require no serious empirical support. Currie makes a case for modesty about learning from fiction—reasoning that a lot of what we take to be learning in this area is itself a kind of pretence, that we are too optimistic about the psychological and moral insights of authors, that the case for fiction as a Darwinian adaptation is weak, and that empathy is both hard to acquire and not always morally advantageous.
