Noncommutative Geometry and Cayley-smooth Orders By: Lieven Le Bruyn Publisher: Chapman and Hall/CRC Print ISBN: 9781420064223, 1420064223 eText ISBN: 9781420064230, 1420064231 Edition: 1st Copyright year: 2007 Format: PDF Available from $ 23.18 USD SKU 9781420064230R90 Noncommutative Geometry and Cayley-smooth Orders explains the theory of Cayley-smooth orders in central simple algebras over function fields of varieties. In particular, the book describes the étale local structure of such orders as well as their central singularities and finite dimensional representations. After an introduction to partial desingularizations of commutative singularities from noncommutative algebras, the book presents the invariant theoretic description of orders and their centers. It proceeds to introduce étale topology and its use in noncommutative algebra as well as to collect the necessary material on representations of quivers. The subsequent chapters explain the étale local structure of a Cayley-smooth order in a semisimple representation, classify the associated central singularity to smooth equivalence, describe the nullcone of these marked quiver representations, and relate them to the study of all isomorphism classes of n-dimensional representations of a Cayley-smooth order. The final chapters study Quillen-smooth algebras via their finite dimensional representations. Noncommutative Geometry and Cayley-smooth Orders provides a gentle introduction to one of mathematics' and physics' hottest topics. Download eBook Free: https://ouo.io/iboj2J
