The first book in the Skolian Empire saga by the Nebula Award–winning author. “Fast, smart, speculative . . . another stellar debut.” —Los Angeles Daily News Soz Valdoria, a bioengineered fighter pilot—and first in line for the military command of her people—has found refuge with her squad on the sanctuary planet of Delos. It offers a respite from the war that rages between her Skolian people and their enemies, the Traders. Looking for rest and relaxation, they must still be on their guard for the Trader soldiers who also visit the sanctuary. In a bar, they confront the worst of the worst: an Aristo from the Trader ruling caste, seemingly on the prowl for a “provider” he can use for his barbaric impulses. His presence takes Soz back to her days as a prisoner of war, when she became the plaything of a sadistic and soulless Aristo. And yet something is off about this Aristo. Unable to ignore her instincts, Soz searches the city until she finds him in a secured mansion. Breaching its fortifications and eluding its guards, she discovers a devastating truth: this man is no true Aristo. He is a genetic anomaly like Soz, one of the few people who can handle the massive neurological demands of the psibernet, the technological marvel that gives the Skolians their only advantage over the Traders. This false Aristo, this sheep in a wolf’s clothing, is heir to the Trader throne. The emperor created him for one reason—to take control of the Skolian network and conquer Soz’s people. But Soz has never felt such a connection as she does to this Trader heir. It may prove her—and the universe’s—undoing . . . “This is one of the best SF first novels in years.” —Booklist

This book describes the theory and practice of inverting seismic data for the subsurface rock properties of the earth. The primary application is for inverting reflection and/or transmission data from engineering or exploration surveys, but the methods described also can be used for earthquake studies. Seismic Inversion will be of benefit to scientists and advanced students in engineering, earth sciences, and physics. It is desirable that the reader has some familiarity with certain aspects of numerical computation, such as finite-difference solutions to partial differential equations, numerical linear algebra, and the basic physics of wave propagation. For those not familiar with the terminology and methods of seismic exploration, a brief introduction is provided. To truly understand the nuances of seismic inversion, we have to actively practice what we preach (or teach). Therefore, computational labs are provided for most of the chapters, and some field data labs are given as well.

It is rarely taught in an undergraduate or even graduate curriculum that the only conformal maps in Euclidean space of dimension greater than two are those generated by similarities and inversions in spheres. This is in stark contrast to the wealth of conformal maps in the plane. The principal aim of this text is to give a treatment of this paucity of conformal maps in higher dimensions. The exposition includes both an analytic proof in general dimension and a differential-geometric proof in dimension three. For completeness, enough complex analysis is developed to prove the abundance of conformal maps in the plane. In addition, the book develops inversion theory as a subject, along with the auxiliary theme of circle-preserving maps. A particular feature is the inclusion of a paper by Caratheodory with the remarkable result that any circle-preserving transformation is necessarily a Mobius transformation, not even the continuity of the transformation is assumed. The text is at the level of advanced undergraduates and is suitable for a capstone course, topics course, senior seminar or independent study. Students and readers with university courses in differential geometry or complex analysis bring with them background to build on, but such courses are not essential prerequisites.

Winner of the Nebula Award, this science fiction adventure “features sound characterization, straightforward plotting, abundant world building detail, and almost as much humor” (Booklist). As the young ruler of a destitute province burdened by obsolete technology, Kamoj Argali must marry to save her people from starvation. She has managed to make peace with her betrothal to the arrogant leader of a wealthy neighboring province. Then Havyrl Lionstar, a mysterious visitor to their land, steps in to claim Kamoj as his wife, sowing chaos in their lives. In this science fictional retelling of a classic folk tale, Havryl appears as a beast to Kamoj’s people. But what is the truth behind his strange, erratic behavior? In dealing with the upheavals he brings to their world, Kamoj discovers that the universe is much larger than she ever understood. This new edition contains a revised, expanded version of the essay that appeared in the original book, in which Catherine Asaro explains how she found inspiration for The Quantum Rose while earning her doctorate at the Harvard-Smithsonian Center for Astrophysics, where she studied the quantum theory of scattering processes. “A freestanding page-turner as a romance, with a hard science fiction framework.” —Publishers Weekly “Bolsters [Asaro’s] reputation for skillfully putting classic romance elements in an sf setting.” —Booklist “Fans of futuristic romance will revel in the delights of a top notch romantic adventure set against an impeccably crafted, richly imagined background.” —Romantic Times “Sturdy and absorbing.” —Kirkus Reviews “Asaro plants herself firmly into that grand SF tradition of future history franchises favored by luminaries like Heinlen, Asimov, Herbert, Anderson, Dickson, Niven, Cherryh, and BaxterBaxter.” —Paul Di Filippo, Locus

Inverse problems are of interest and importance across many branches of physics, mathematics, engineering and medical imaging. In this text, the foundations of imaging and wavefield inversion are presented in a clear and systematic way. The necessary theory is gradually developed throughout the book, progressing from simple wave equation based models to vector wave models. By combining theory with numerous MATLAB based examples, the author promotes a complete understanding of the material and establishes a basis for real world applications. Key topics of discussion include the derivation of solutions to the inhomogeneous and homogeneous Helmholtz equations using Green function techniques; the propagation and scattering of waves in homogeneous and inhomogeneous backgrounds; and the concept of field time reversal. Bridging the gap between mathematics and physics, this multidisciplinary book will appeal to graduate students and researchers alike. Additional resources including MATLAB codes and solutions are available online at www.cambridge.org/9780521119740.

“Powerful characterization and intriguing scientific concepts . . . an elegant subtlety and a far-reaching sense of destiny that carries [Asaro] to the highest rank of master storyteller.” —Romantic Times Reeling from a battle, pilot Kelric Valdoria crash-lands his Jag starfighter on Coba, the closest safe planet he can find after a Trader squad cripples his ship. Although the military of Kelric’s people have given Coba Restricted status, Kelric sees no reason for such draconian measures to isolate the seemingly benign world. While recovering, the dashing Kelric becomes the target of affection for high-powered women in Coba’s matriarchal society, including Deha Dahl, an Estate Manager, and young Ixpar Karn, the chosen successor of the Minister. Distracted by their flirtations, Kelric doesn’t at first realize the Restricted status of the planet was their own choice—and that they can’t risk letting him go. However, Kelric’s internal biomech system is failing, causing his brain to malfunction. His only hope is to escape. But when his attempt fails, ending in the death of a guard, he must face a trial that could mean his execution, unless he can win the trust of the people who both covet and fear him . . . “Well-written, entertaining, classic science fiction fun.” —The Plain Dealer “Impossible to put down.” —L. E. Modesitt, Jr., New York Times–bestselling author “A smoothly absorbing space opera that mixes high-tech gimmickry with galactic politics and plenty of romance.” —Publishers Weekly
