Available in PDF, EPUB and Kindle. Book excerpt: This is the first book of its kind on seismic amplitude inversion in the context of reflection tomography. The aim of the monograph is to advocate the use of ray-amplitude data, separately or jointly with traveltime data, in reflection seismic tomography.The emphasis of seismic exploration is on imaging techniques, so that seismic section can be interpreted directly as a geological section. In contrast it is perhaps ironic that, in decades of industrial seismology, one major aspect of waveform data that potentially is easier to measure and analyse has generally been ignored. That is, the information content of seismic amplitudes. Perhaps the potential complexity has deterred most researchers from a more thorough investigation of the practical use of seismic amplitude data. The author of this volume presents an authoritative and detailed study of amplitude data, as used in conjunction with traveltime data, to provide better constraints on the variation of seismic wave speed in the subsurface.One of the fundamental problems in conventional reflection seismic tomography using only traveltime data is the possible ambiguity between the velocity variation and the reflector depth. The inclusion of amplitude data in the inversion may help to resolve this problem because the amplitudes and traveltimes are sensitive to different features of the subsurface model, and thereby provide more accurate information about the subsurface structure and the velocity distribution. An essential goal of this monograph is to make the amplitude inversion method work with real reflection seismic data.

Download or read book Arrangements of Hyperplanes written by Peter Orlik and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: An arrangement of hyperplanes is a finite collection of codimension one affine subspaces in a finite dimensional vector space. Arrangements have emerged independently as important objects in various fields of mathematics such as combinatorics, braids, configuration spaces, representation theory, reflection groups, singularity theory, and in computer science and physics. This book is the first comprehensive study of the subject. It treats arrangements with methods from combinatorics, algebra, algebraic geometry, topology, and group actions. It emphasizes general techniques which illuminate the connections among the different aspects of the subject. Its main purpose is to lay the foundations of the theory. Consequently, it is essentially self-contained and proofs are provided. Nevertheless, there are several new results here. In particular, many theorems that were previously known only for central arrangements are proved here for the first time in completegenerality. The text provides the advanced graduate student entry into a vital and active area of research. The working mathematician will findthe book useful as a source of basic results of the theory, open problems, and a comprehensive bibliography of the subject.
Download or read book Unitary Reflection Groups written by Gustav I. Lehrer and published by Cambridge University Press. This book was released on 2009-08-13 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unitary reflection is a linear transformation of a complex vector space that fixes each point in a hyperplane. Intuitively, it resembles the transformation an image undergoes when it is viewed through a kaleidoscope, or an arrangement of mirrors. This book gives a complete classification of all finite groups which are generated by unitary reflections, using the method of line systems. Irreducible groups are studied in detail, and are identified with finite linear groups. The new invariant theoretic proof of Steinberg's fixed point theorem is treated fully. The same approach is used to develop the theory of eigenspaces of elements of reflection groups and their twisted analogues. This includes an extension of Springer's theory of regular elements to reflection cosets. An appendix outlines links to representation theory, topology and mathematical physics. Containing over 100 exercises, ranging in difficulty from elementary to research level, this book is ideal for honours and graduate students, or for researchers in algebra, topology and mathematical physics.

Download or read book Hessians written by Friederike Baer and published by Oxford University Press. This book was released on 2022 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 1776 and 1783, Britain hired an estimated 30,000 German soldiers to fight in its war against the Americans. Collectively known as Hessians, they actually came from six German territories within the Holy Roman Empire. Over the course of the war, members of the German corps, including women and children, spent extended periods of time in locations as dispersed and varied as Canada in the North to West Florida and Cuba in the South. They shared in every significant British military triumph and defeat. Thousands died of disease, were killed in battle, were captured by the enemy, or deserted. Collectively, they recorded their experiences and observations of the war they fought in, the land they traversed, and the people they encountered in a large body of letters, diaries, and similar private and official records. Friederike Baer presents a study of Britain's war against the American rebels from the perspective of the German soldiers, a people uniquely positioned both in the midst of the war and at its margins. The book offers a ground-breaking reimagining of this watershed event in world history.

Download or read book Reflection Groups and Coxeter Groups written by James E. Humphreys and published by Cambridge University Press. This book was released on 1992-10 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This graduate textbook presents a concrete and up-to-date introduction to the theory of Coxeter groups. The book is self-contained, making it suitable either for courses and seminars or for self-study. The first part is devoted to establishing concrete examples. Finite reflection groups acting on Euclidean spaces are discussed, and the first part ends with the construction of the affine Weyl groups, a class of Coxeter groups that plays a major role in Lie theory. The second part (which is logically independent of, but motivated by, the first) develops from scratch the properties of Coxeter groups in general, including the Bruhat ordering and the seminal work of Kazhdan and Lusztig on representations of Hecke algebras associated with Coxeter groups is introduced. Finally a number of interesting complementary topics as well as connections with Lie theory are sketched. The book concludes with an extensive bibliography on Coxeter groups and their applications.

Available in PDF, EPUB and Kindle. Book excerpt: Published to commemorate the bicentennial of Thomas Paine's death, these texts have remained two of the most influential arguments for liberty in political thought. Common Sense is a pamphlet that Paine wrote in support of American independence. Due to its original and simple style it spread like wildfire through the colonies, inspiring the American Revolution. The Rights of Man is Paine's passionate defense of the French Revolution that led to his trial for sedition and libel. The acclaimed historian Peter Linebaugh provides an original examination of Paine's thought and legacy.
Download or read book Regular Complex Polytopes written by Coxeter and published by Cambridge University Press. This book was released on 1975-03-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of regular solids exercise a fascination which often appeals strongly to the mathematically inclined, whether they are professionals, students or amateurs. In this classic book Professor Coxeter explores these properties in easy stages, introducing the reader to complex polyhedra (a beautiful generalization of regular solids derived from complex numbers) and unexpected relationships with concepts from various branches of mathematics: magic squares, frieze patterns, kaleidoscopes, Cayley diagrams, Clifford surfaces, crystallographic and non-crystallographic groups, kinematics, spherical trigonometry, and algebraic geometry. In the latter half of the book, these preliminary ideas are put together to describe a natural generalization of the Five Platonic Solids. This updated second edition contains a new chapter on Almost Regular Polytopes, with beautiful 'abstract art' drawings. New exercises and discussions have been added throughout the book, including an introduction to Hopf fibration and real representations for two complex polyhedra.
