The goal of this book is to present a portrait of the n n-dimensional Cremona group with an emphasis on the 2-dimensional case. After recalling some crucial tools, the book describes a naturally defined infinite dimensional hyperbolic space on which the Cremona group acts. This space plays a fundamental role in the study of Cremona groups, as it allows one to apply tools from geometric group theory to explore properties of the subgroups of the Cremona group as well as the degree growth and dynamical behavior of birational transformations. The book describes natural topologies on the Cremona group, codifies the notion of algebraic subgroups of the Cremona groups and finishes with a chapter on the dynamics of their actions. This book is aimed at graduate students and researchers in algebraic geometry who are interested in birational geometry and its interactions with geometric group theory and dynamical systems.

From the ancient city of Jerusalem to the mountains of New York, the Scrolls of Onteora, known as the Cremona Document, tell the story of the Knights Templars who found artifacts and documents, revealing how the scrolls were transported to the Americas - centuries before they were settled by Europeans. Learn the meaning of these artifacts found beneath the walls of Jerusalem and follow Ralph de Sudeley and his companions as they endeavor to recover these lost scrolls. Examine the pictures and documents that Don Ruh has accumulated about them over the last 30 years and weigh the evidence yourself.

Councillor Krespel is an eccentric violin maker who lives with the mysterious Antonia. Considered to have the most beautiful singing voice the town has ever heard; she has only sung once in her life. Krespel is renowned for making the finest violins in the world, but never sells any and plays each violin he makes only once. What is the dark secret behind this odd couple’s behaviour? This classic short horror story was written by the famous German Romantic author E.T.A. Hoffmann and is perfect for fans of authors H.P. Lovecraft and Neil Gaiman. Ernst Theodor Wilhelm Hoffmann (1776-1822), better known as E. T. A. Hoffmann, was a German Romantic author of fantasy and gothic horror. He was also a composer, music critic, draftsman and caricaturist. Hoffmann's stories inspired several famous operatic composers, including Richard Wagner, Jacques Offenbach and Léo Delibes. He is also the author of the novella ‘The Nutcracker and the Mouse King’, on which Tchaikovsky’s famous ballet, ‘The Nutcracker’ is based. The story also inspired the film ‘The Nutcracker and the Four Realms’ (2018), starring Keira Knightley, Morgan Freeman, Helen Mirren.

This book contains a brief account of the history of Cremona violins - the rise and fall of the art that dominated over two centuries - and is primarily devoted to The physics behind the violin acoustics, specifically the research of William F "Jack" Fry over the past four decades and more. it chronicles his early research and The evolution of his ideas leading to a holistic approach to its acoustics, In sharp contrast to The conventional "reductionist" approach. With rare insights, he has come closer than anyone before in reproducing the sound of the great Italian masters. This historic achievement makes the book extremely valuable for violin makers, violin researchers, and young and aspiring violinists who would like to own excellent-sounding instruments with all the desirable characteristics of old instruments at affordable prices.

Ernst Theodor Amadeus Hoffmann (commonly abbreviated as E. T. A. Hoffmann; born Ernst Theodor Wilhelm Hoffmann; 24 January 1776 - 25 June 1822), was a Prussian Romantic author of fantasy and horror, a jurist, composer, music critic, draftsman and caricaturist. His stories form the basis of Jacques Offenbach's famous opera "The Tales of Hoffmann," in which Hoffmann appears (heavily fictionalized) as the hero. He is also the author of the novella "The Nutcracker and the Mouse King," on which the famous ballet "The Nutcracker" is based. The ballet "Coppelia" is based on two other stories that Hoffmann wrote, while Schumann's "Kreisleriana" is based on Hoffmann's character Johannes Kreisler. Hoffmann's stories were very influential during the 19th century, and he is one of the major authors of the Romantic movement."

Canadian Children's Book Centre Our Choice Matthew's dad is the strongest man this side of Cremona. He can lift Matthew over fences, and when he shouts at the cows, they scatter. But while helping repair a fence on their dairy farm, Matthew encounters something stronger than his dad: a tornado sweeping a path of devastation across the prairie. Thanks to his dad's quick thinking, they survive the tornado. But it has left Matthew shaken, and their beautiful farm has been damaged almost beyond recognition. While friends gather to help rebuild, Matthew discovers that the love he and his father share must be the strongest thing of all.

This book provides a self-contained exposition of the theory of plane Cremona maps, reviewing the classical theory. The book updates, correctly proves and generalises a number of classical results by allowing any configuration of singularities for the base points of the plane Cremona maps. It also presents some material which has only appeared in research papers and includes new, previously unpublished results. This book will be useful as a reference text for any researcher who is interested in the topic of plane birational maps.

Cremona Groups and the Icosahedron focuses on the Cremona groups of ranks 2 and 3 and describes the beautiful appearances of the icosahedral group A5 in them. The book surveys known facts about surfaces with an action of A5, explores A5-equivariant geometry of the quintic del Pezzo threefold V5, and gives a proof of its A5-birational rigidity.The a
