Download or read book Control and Relaxation over the Circle written by Bruce Hughes and published by American Mathematical Soc.. This book was released on 2000 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work formulates and proves a geometric version of the fundamental theorem of algebraic K-theory which relates the K-theory of the Laurent polynomial extension of a ring to the K-theory of the ring. The geometric version relates the higher simple homotopy theory of the product of a finite complex and a circle with that of the complex. By using methods of controlled topology, we also obtain a geometric version of the fundamental theorem of lower algebraic K-theory. The main new innovation is a geometrically defined nil space.
