This book describes the representations of Lie superalgebras that are yielded by a graded version of Hudson-Parthasarathy quantum stochastic calculus. Quantum stochastic calculus and grading theory are given concise introductions, extending readership to mathematicians and physicists with a basic knowledge of algebra and infinite-dimensional Hilbert spaces. The develpment of an explicit formula for the chaotic expansion of a polynomial of quantum stochastic integrals is particularly interesting. The book aims to provide a self-contained exposition of what is known about Z_2-graded quantum stochastic calculus and to provide a framework for future research into this new and fertile area.

In the all-too-immediate future, the day has finally come when crime, drugs, and pollution have made the cities of the world virtually uninhabitable. Gangs roam the streets at will, the police have nearly surrendered, and the air and water are slowly killing the residents who remain. But one small group of survivors has decided to escape the madness. Packing what they can carry, they head off to what they hope will be the unspoiled wilderness of northern Canada, intent on making a new start, a new life. But nature isn't that forgiving. For far too long mankind has destroyed the planet, ravaging the landscape and slaughtering the animals. At long last, nature has had enough. Now the Earth is ready to fight back, to rid itself of its abusers. A new day has come. But will anyone survive...

C.J. Cherryh

One of science fiction's greatest writers -- a three-time Hugo Award winner -- introduces an all-new universe for the first time in decades. An innocent desert world is trapped between two hostile interstellar empires.One of the most renowned figures in science fiction, C. J. Cherryh has been enthralling audiences for nearly thirty years with rich and complex novels. Now at the peak of her career, this three-time Hugo Award Winner launches her most ambitious work in decades, Hammerfall, part of a far-ranging series, The Gene Wars, set in an entirely new universe scarred by the most vicious of future weaponry, nanotechnology. In this brilliant novel -- possibly Cherryh's masterwork -- the fate of billions has come down to a confrontation between two profoundly alien cultures on a single desert planet.

A bizarre other world occupying the same space as ours... a place shrouded in pulsating nightmarish mists that lived and killed... where thoughts could become realities and realities were irrelevant... where primitive Toparians battled telepathic Vorteds for survival... and where three desperate aliens from earth raced against time that had no meaning to save the future...
