Sommario/riassunto |
|
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 a marvelous source of examples in algebraic geometry. In the other direction, general facts from algebraic geometry have implications for such polytopes, such as to the problem of the number of lattice points they contain. In spite of the fact that toric varieties are very special in the spectrum of all algebraic varieties, they provide a remarkably useful testing ground for general theories. The aim of this mini-course is to develop the foundations of the study of toric varieties, with examples, and describe some of these relations and applications. The text concludes with Stanley's theorem characterizing the numbers of simplicies in each dimension in a convex simplicial polytope. Although some general theorems are "ed without proof, the concrete interpretations via simplicial geometry should make the text accessible to beginners in algebraic geometry. |

Sommario/riassunto |

The present volume is a collection of papers on Contrastive Pragmatics, involving research on interlanguage and cross-cultural perspectives with a focus on second language acquisition contexts. The subdiscipline of pragmatics is seen from a multilingual and multicultural perspective thus contributing to an emerging field of study, i.e. intercultural pragmatics which can be made fruitful to second language teaching/learning and contrastive analysis. The book is an important contribution to general linguistics, pragmatics, cross-cultural communication, second language acquisition, as well as min |
