What is the Genus?

What is the Genus? PDF Author: Patrick Popescu-Pampu
Publisher: Springer
ISBN: 3319423126
Category : Mathematics
Languages : en
Pages : 181

Book Description
Exploring several of the evolutionary branches of the mathematical notion of genus, this book traces the idea from its prehistory in problems of integration, through algebraic curves and their associated Riemann surfaces, into algebraic surfaces, and finally into higher dimensions. Its importance in analysis, algebraic geometry, number theory and topology is emphasized through many theorems. Almost every chapter is organized around excerpts from a research paper in which a new perspective was brought on the genus or on one of the objects to which this notion applies. The author was motivated by the belief that a subject may best be understood and communicated by studying its broad lines of development, feeling the way one arrives at the definitions of its fundamental notions, and appreciating the amount of effort spent in order to explore its phenomena.

Genus

Genus PDF Author: Jonathan Trigell
Publisher: Hachette UK
ISBN: 1849017514
Category : Fiction
Languages : en
Pages : 223

Book Description
In the Britain of a few tomorrows time, physical perfection is commonplace and self improvement has become an extinct expression: all the qualities men and women could aspire to can be purchased prior to birth. GENUS is a time of genetic selection and enrichment - life chances come on a sliding scale according to wealth. For some there is no money or choice, and an underclass has evolved; London's King's Cross, or The Kross as it is now known, has become a ghetto for the Unimproved. In The Kross, the natural, the dated, the cheap and the dull, live a brittle and unenviable existence. But unrest is growing; tension is mounting and a murderer is abroad in these dark quarters... Acclaimed author Jonathan Trigell's third novel is a breathtaking tour de force, exploring a dystopia of the not-too-distant-a future which will leave readers wondering not 'what if', as the original audience of Huxley's Brave New World did, but 'when'. Praise for Jonathan Trigell: 'A compelling narrative, a beautifully structured piece of writing, and a thought-provoking novel of ideas. It's a wonderful debut.' - Sarah Waters, Chair of the Judges for the John Llewellyn Rhys Prize on Boy A 'A fine and moving debut novel... compulsively readable... a rare treat' The Independent on Boy A 'Does for extreme winter sports what Alex Garland's The Beach did for backpacking.' - Financial Times on Cham.

God without Parts

God without Parts PDF Author: James E. Dolezal
Publisher: Wipf and Stock Publishers
ISBN: 1621891097
Category : Religion
Languages : en
Pages : 260

Book Description
The doctrine of divine simplicity has long played a crucial role in Western Christianity's understanding of God. It claimed that by denying that God is composed of parts Christians are able to account for his absolute self-sufficiency and his ultimate sufficiency as the absolute Creator of the world. If God were a composite being then something other than the Godhead itself would be required to explain or account for God. If this were the case then God would not be most absolute and would not be able to adequately know or account for himself without reference to something other than himself. This book develops these arguments by examining the implications of divine simplicity for God's existence, attributes, knowledge, and will. Along the way there is extensive interaction with older writers, such as Thomas Aquinas and the Reformed scholastics, as well as more recent philosophers and theologians. An attempt is made to answer some of the currently popular criticisms of divine simplicity and to reassert the vital importance of continuing to confess that God is without parts, even in the modern philosophical-theological milieu.

Rereading the Fossil Record

Rereading the Fossil Record PDF Author: David Sepkoski
Publisher: University of Chicago Press
ISBN: 022627294X
Category : Science
Languages : en
Pages : 441

Book Description
Rereading the Fossil Record presents the first-ever historical account of the origin, rise, and importance of paleobiology, from the mid-nineteenth century to the late 1980s. Drawing on a wealth of archival material, David Sepkoski shows how the movement was conceived and promoted by a small but influential group of paleontologists and examines the intellectual, disciplinary, and political dynamics involved in the ascendency of paleobiology. By tracing the role of computer technology, large databases, and quantitative analytical methods in the emergence of paleobiology, this book also offers insight into the growing prominence and centrality of data-driven approaches in recent science.

Freshwater Algae of North America

Freshwater Algae of North America PDF Author: John D. Wehr
Publisher: Elsevier
ISBN: 0123858771
Category : Science
Languages : en
Pages : 1067

Book Description
Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms. - Extensive and complete - Describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus. - Full-color images throughout provide superb visual examples of freshwater algae - Updated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB) - Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problems - Updated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies

The Genus Citrus

The Genus Citrus PDF Author: Manuel Talon
Publisher: Woodhead Publishing
ISBN: 012812217X
Category : Technology & Engineering
Languages : en
Pages : 540

Book Description
The Genus Citrus presents the enormous amount of new knowledge that has been generated in recent years on nearly all topics related to citrus. Beginning with an overview of the fundamental principles and understanding of citrus biology and behavior, the book provides a comprehensive view from Citrus evolution to current market importance. Reporting on new insights supported by the elucidation of the citrus genome sequence, it presents groundbreaking theories and fills in previous knowledge gaps. Because citrus is among the most difficult plants to improve through traditional breeding, citrus researchers, institutions and industries must quickly learn to adapt to new developments, knowledge and technologies to address the biological constraints of a unique fruit-tree such as citrus. Despite the challenges of working with citrus, tremendous progress has been made, mostly through advances in molecular biology and genomics. This book is valuable for all those involved with researching and advancing, producing, processing, and delivering citrus products. - Includes the most current research on citrus genomic information - Provides the first detailed description of citrus origin, a new proposal for citrus taxonomy, and a redefinition of the genus Citrus - Details citrus challenges including climate change, global disease impacts, and plant improvement strategies
