內容簡介

　　《國外數(shù)學名著系列（續(xù)1）（影印版）49：計算不變量理論》is about the computational aspects of invariant theory.Of central interest is the question how the invariant ring of a given group action can be calculated. Algorithms for this purpose form the main pillars around which the book is built. There are two introductory chapters， one on GrObner basis methods and one on the basic concepts of invariant theory， which prepare the ground for the algorithms. Then algorithms for computing invariants of finite and reductive groups are discussed. Particular emphasis lies on interrelations between structural properties of invariant rings and computational methods. Finally， the book contains a chapter on applications of invariant theory， covering fields as disparate as graph theory， coding theory， dynamical systems， and computer vision.The book is intended for postgraduate students as well as researchers in geometry， computer algebra， and， of course， invariant theory. The text is enriched with numerous explicit examples which illustrate the theoiw and should be of more than passing interest.
