Effective Faithful Tropicalizations Associated to Linear Systems on Curves

Languages : en
Pages : 110
Book Description
For a connected smooth projective curve X of genus g, global sections of any line bundle L with deg(L) ≥ 2g + 1 give an embedding of the curve into projective space. We consider an analogous statement for a Berkovich skeleton in nonarchimedean geometry: We replace projective space by tropical projective space, and an embedding by a homeomorphism onto its image preserving integral structures (or equivalently, since X is a curve, an isometry), which is called a faithful tropicalization. Let K be an algebraically closed field which is complete with respect to a nontrivial nonarchimedean value. Suppose that X is defined over K and has genus g ≥ 2 and that Γ is a skeleton (that is allowed to have ends) of the analytification Xan of X in the sense of Berkovich. We show that if deg(L) ≥ 3g − 1, then global sections of L give a faithful tropicalization of Γ into tropical projective space. As an application, when Y is a suitable affine curve, we describe the analytification Y an as the limit of tropicalizations of an effectively bounded degree.

An Eye for the Tropics
Author: Krista A. ThompsonPublisher: Duke University Press
ISBN: 0822388561
Category : Photography
Languages : en
Pages : 421
Book Description
Images of Jamaica and the Bahamas as tropical paradises full of palm trees, white sandy beaches, and inviting warm water seem timeless. Surprisingly, the origins of those images can be traced back to the roots of the islands’ tourism industry in the 1880s. As Krista A. Thompson explains, in the late nineteenth century, tourism promoters, backed by British colonial administrators, began to market Jamaica and the Bahamas as picturesque “tropical” paradises. They hired photographers and artists to create carefully crafted representations, which then circulated internationally via postcards and illustrated guides and lectures. Illustrated with more than one hundred images, including many in color, An Eye for the Tropics is a nuanced evaluation of the aesthetics of the “tropicalizing images” and their effects on Jamaica and the Bahamas. Thompson describes how representations created to project an image to the outside world altered everyday life on the islands. Hoteliers imported tropical plants to make the islands look more like the images. Many prominent tourist-oriented spaces, including hotels and famous beaches, became off-limits to the islands’ black populations, who were encouraged to act like the disciplined, loyal colonial subjects depicted in the pictures. Analyzing the work of specific photographers and artists who created tropical representations of Jamaica and the Bahamas between the 1880s and the 1930s, Thompson shows how their images differ from the English picturesque landscape tradition. Turning to the present, she examines how tropicalizing images are deconstructed in works by contemporary artists—including Christopher Cozier, David Bailey, and Irénée Shaw—at the same time that they remain a staple of postcolonial governments’ vigorous efforts to attract tourists.

The Shaken and the Stirred
Author: Stephen SchneiderPublisher: Indiana University Press
ISBN: 025304975X
Category : Cooking
Languages : en
Pages : 432
Book Description
Over the past decade, the popularity of cocktails has returned with gusto. Amateur and professional mixologists alike have set about recovering not just the craft of the cocktail, but also its history, philosophy, and culture. The Shaken and the Stirred features essays written by distillers, bartenders and amateur mixologists, as well as scholars, all examining the so-called 'Cocktail Revival' and cocktail culture. Why has the cocktail returned with such force? Why has the cocktail always acted as a cultural indicator of class, race, sexuality and politics in both the real and the fictional world? Why has the cocktail revival produced a host of professional organizations, blogs, and conferences devoted to examining and reviving both the drinks and habits of these earlier cultures?
New York Ricans from the Hip Hop Zone
Author: R. RiveraPublisher: Springer
ISBN: 1403981671
Category : Social Science
Languages : en
Pages : 285
Book Description
New York Puerto Ricans have been an integral part of hip hop culture since day one: from 1970s pioneers like Rock Steady Crew's Jo-Jo, to recent rap mega-stars Big Punisher (R.I.P.) and Angie Martinez. Yet, Puerto Rican participation and contributions to hip hop have often been downplayed and even completely ignored. And when their presence has been acknowledged, it has frequently been misinterpreted as a defection from Puerto Rican culture and identity, into the African American camp. But nothing could be further from the truth. Through hip hop, Puerto Ricans have simply stretched the boundaries of Puerto Ricanness and latinidad.
Nonarchimedean and Tropical Geometry
Author: Matthew BakerPublisher: Springer
ISBN: 3319309455
Category : Mathematics
Languages : en
Pages : 534
Book Description
This volume grew out of two Simons Symposia on "Nonarchimedean and tropical geometry" which took place on the island of St. John in April 2013 and in Puerto Rico in February 2015. Each meeting gathered a small group of experts working near the interface between tropical geometry and nonarchimedean analytic spaces for a series of inspiring and provocative lectures on cutting edge research, interspersed with lively discussions and collaborative work in small groups. The articles collected here, which include high-level surveys as well as original research, mirror the main themes of the two Symposia. Topics covered in this volume include: Differential forms and currents, and solutions of Monge-Ampere type differential equations on Berkovich spaces and their skeletons; The homotopy types of nonarchimedean analytifications; The existence of "faithful tropicalizations" which encode the topology and geometry of analytifications; Relations between nonarchimedean analytic spaces and algebraic geometry, including logarithmic schemes, birational geometry, and the geometry of algebraic curves; Extended notions of tropical varieties which relate to Huber's theory of adic spaces analogously to the way that usual tropical varieties relate to Berkovich spaces; and Relations between nonarchimedean geometry and combinatorics, including deep and fascinating connections between matroid theory, tropical geometry, and Hodge theory.
Introduction to Tropical Geometry
Author: Diane MaclaganPublisher: American Mathematical Society
ISBN: 1470468565
Category : Mathematics
Languages : en
Pages : 363
Book Description
Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of the six chapters concludes with problems that will help the readers to practice their tropical skills, and to gain access to the research literature. This wonderful book will appeal to students and researchers of all stripes: it begins at an undergraduate level and ends with deep connections to toric varieties, compactifications, and degenerations. In between, the authors provide the first complete proofs in book form of many fundamental results in the subject. The pages are sprinkled with illuminating examples, applications, and exercises, and the writing is lucid and meticulous throughout. It is that rare kind of book which will be used equally as an introductory text by students and as a reference for experts. —Matt Baker, Georgia Institute of Technology Tropical geometry is an exciting new field, which requires tools from various parts of mathematics and has connections with many areas. A short definition is given by Maclagan and Sturmfels: “Tropical geometry is a marriage between algebraic and polyhedral geometry”. This wonderful book is a pleasant and rewarding journey through different landscapes, inviting the readers from a day at a beach to the hills of modern algebraic geometry. The authors present building blocks, examples and exercises as well as recent results in tropical geometry, with ingredients from algebra, combinatorics, symbolic computation, polyhedral geometry and algebraic geometry. The volume will appeal both to beginning graduate students willing to enter the field and to researchers, including experts. —Alicia Dickenstein, University of Buenos Aires, Argentina
