Publisher's Synopsis
Excerpt from A New Lower Bound Construction for the Word Problem for Commutative Thue Systems
Let be a commutative Thue System, 2 Let R denote the polynomial ring q[z] where Q is the field of rational numbers. For each rule a 5 6 S, we form the polynomial fl - a 6 R, and let F5 denote the resulting set of polynomials. The word problem (for commutative Thue systems) is this: Given B) where a,fl are commutative words over 2, we want to know if a fl(mods). The ideal membership problem is this: Given (f, f) where F Q R is a finite set of polynomials and f G R, we want to know if f 6 (f) where (f) Q R is the ideal generated by F. As shown in the word problem can be reduced to the ideal membership problem as follows. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
