This book is the ninth volume in a series whose goal is to furnish a careful and largely self-contained proof of the classification theorem for the finite simple groups. Having completed the classification of the simple groups of odd type as well as the classification of the simple groups of generic even type (modulo uniqueness theorems to appear later), the current volume begins the classification of the finite simple groups of special even type. The principal result of this volume is a classification of the groups of bicharacteristic type, i.e., of both even type and of $p$-type for a suitable odd prime $p$. It is here that the largest sporadic groups emerge, namely the Monster, the Baby Monster, the largest Conway group, and the three Fischer groups, along with six finite groups of Lie type over small fields, several of which play a major role as subgroups or sections of these sporadic groups.

This book completes a trilogy (Numbers 5, 7, and 8) of the series The Classification of the Finite Simple Groups treating the generic case of the classification of the finite simple groups. In conjunction with Numbers 4 and 6, it allows us to reach a major milestone in our series--the completion of the proof of the following theorem: Theorem O: Let G be a finite simple group of odd type, all of whose proper simple sections are known simple groups. Then either G is an alternating group or G is a finite group of Lie type defined over a field of odd order or G is one of six sporadic simple groups. Put another way, Theorem O asserts that any minimal counterexample to the classification of the finite simple groups must be of even type. The work of Aschbacher and Smith shows that a minimal counterexample is not of quasithin even type, while this volume shows that a minimal counterexample cannot be of generic even type, modulo the treatment of certain intermediate configurations of even type which will be ruled out in the next volume of our series.

The classification of finite simple groups is a landmark result of modern mathematics. The multipart series of monographs which is being published by the AMS (Volume 40.1-40.7 and future volumes) represents the culmination of a century-long project involving the efforts of scores of mathematicians published in hundreds of journal articles, books, and doctoral theses, totaling an estimated 15,000 pages. This part 7 of the series is the middle of a trilogy (Volume 40.5, Volume 40.7, and forthcoming Volume 40.8) treating the Generic Case, i.e., the identification of the alternating groups of degree at least 13 and most of the finite simple groups of Lie type and Lie rank at least 4. Moreover, Volumes 40.4-40.8 of this series will provide a complete treatment of the simple groups of odd type, i.e., the alternating groups (with two exceptions) and the groups of Lie type defined over a finite field of odd order, as well as some of the sporadic simple groups. In particular, this volume completes the construction, begun in Volume 40.5, of a collection of neighboring centralizers of a particularly nice form. All of this is then applied to complete the identification of the alternating groups of degree at least 13. The book is suitable for graduate students and researchers interested in the theory of finite groups.

With the classification of finite groups an era of research in that subject ended. In this symposium volume twenty-nine key figures in the classification programme analyse the likely directions research will take in the future.

The classification of finite simple groups is a landmark result of modern mathematics. The original proof is spread over scores of articles by dozens of researchers. In this multivolume book, the authors are assembling the proof with explanations and references. It is a monumental task. The book, along with background from sections of the previous volumes, presents critical aspects of the classification. In four prior volumes (Surveys of Mathematical Monographs, Volumes 40.1, 40.2, 40.3, and 40.4), the authors began the proof of the classification theorem by establishing certain uniqueness and preuniqueness results. In this volume, they now begin the proof of a major theorem from the classification grid, namely Theorem ${\mathcal C 7$. The book is suitable for graduate students and researchers interested in group theory.

During the eighteenth and nineteenth centuries, North American Indian leaders commonly signed treaties with the European powers and the American and Canadian governments with an "X," signifying their presence and assent to the terms. These x-marks indicated coercion (because the treaties were made under unfair conditions), resistance (because they were often met with protest), and acquiescence (to both a European modernity and the end of a particular moment of Indian history and identity). In "X-Marks," Scott Richard Lyons explores the complexity of contemporary Indian identity and current debates among Indians about traditionalism, nationalism, and tribalism. Employing the x-mark as a metaphor for what he calls the "Indian assent to the new," Lyons offers a valuable alternative to both imperialist concepts of assimilation and nativist notions of resistance, calling into question the binary oppositions produced during the age of imperialism and maintaining that indigeneity is something that people do, not what they are. Drawing on his personal experiences and family history on the Leech Lake Ojibwe Reservation in northern Minnesota, discourses embedded in "Ojibwemowin" (the Ojibwe language), and disagreements about Indian identity within Native American studies, Lyons contends that Indians should be able to choose nontraditional ways of living, thinking, and being without fear of being condemned as inauthentic. Arguing for a greater recognition of the diversity of Native America, "X-Marks" analyzes ongoing controversies about Indian identity, addresses the issue of culture and its use and misuse by essentialists, and considers the implications of the idea of an Indian nation. At once intellectually rigorous and deeply personal, "X-Marks" holds that indigenous peoples can operate in modern times while simultaneously honoring and defending their communities, practices, and values.
