Toric varieties form a beautiful and accessible part of modern algebraic geometry. This book covers the standard topics in toric geometry; a novel feature is that each of the first nine chapters contains an introductory section on the necessary background material in algebraic geometry. Other topics covered include quotient constructions, vanishing theorems, equivariant cohomol...(展开全部)

Toric varieties are algebraic varieties arising from elementary geometric and combinatorial objects such as convex polytopes in Euclidean space with vertices on lattice points. Since many algebraic geometry notions such as singularities, birational maps, cycles, homology, intersection theory, and Riemann-Roch translate into simple facts about polytopes, toric varieties provide ...(展开全部)

The world shows up for us - it is present in our thought and perception. But, as Alva Noe contends in his latest exploration of the problem of consciousness, it doesn't show up for free. The world is not simply available; it is achieved rather than given. As with a painting in a gallery, the world has no meaning - no presence to be experienced - apart from our able engagement w...(展开全部)

Recent work on consciousness has featured a number of debates on the existence and character of controversial types of phenomenal experience. Perhaps the best-known is the debate over the existence of a sui generis, irreducible cognitive phenomenology, a phenomenology proper to thought. Another concerns the existence of a sui generis phenomenology of agency. Such debates bring ...(展开全部)

Mavis Gallant is the modern master of what Henry James called the international story, the fine-grained evocation of the quandaries of people who must make their way in the world without any place to call their own. The irreducible complexity of the very idea of home is especially at issue in the stories Gallant has written about Montreal, where she was born, although she has l...(展开全部)
