• Sommario/riassunto: This volume deals with the theory of finite topological spaces and its relationship with the homotopy and simple homotopy theory of ; polyhedra. The interaction between their intrinsic combinatorial and topological structures makes finite spaces a useful tool for studying problems in Topology, Algebra and Geometry from a new perspective. In particular, the methods developed in this manuscript are used to study Quillen’s conjecture on the poset of p-subgroups of a finite group and the Andrews-Curtis conjecture on the 3-deformability of contractible two-dimensional complexes. This self-contained work constitutes the first detailed exposition on the algebraic topology of finite spaces. It is intended for topologists and combinatorialists, but it is also recommended for advanced undergraduate students and graduate students with a modest knowledge of Algebraic Topology.

• Sommario/riassunto: "In 1670, the ancient homeland of the Cree and Ojibwe people of Hudson Bay became known to the English entrepreneurs of the Hudson's Bay Company as Rupert's Land, after the founder and absentee landlord, Prince Rupert. For four decades, Jennifer S.H. Brown has examined the complex relationships that developed among the newcomers and the Algonquian communities--who hosted and tolerated the fur traders--and later, the missionaries, anthropologists, and others who found their way into Indigenous lives and territories. The eighteen essays gathered in this book explore Brown's investigations into the surprising range of interactions among Indigenous people and newcomers as they met or observed one another from a distance, and as they competed, compromised, and rejected or adapted to change. While diverse in their subject matter, the essays have thematic unity in their focus on the old HBC territory and its peoples from the 1600s to the present. More than an anthology, the chapters of An Ethnohistorian in Rupert's Land provide examples of Brown's exceptional skill in the close study of texts, including oral documents, images, artifacts, and other cultural expressions. The volume as a whole represents the scholarly evolution of one of the leading ethnohistorians in Canada and the United States."--
