CONFIGURATIONS IN ALGEBRAIC GEOMETRY

Computational algebraic geometry

Algebraic geometry is a powerful combination of algebra and geometry, with a rich history and many applications, both theoretical and practical. It also has an intimidating reputation. Hence it is important to have a variety of introductory texts at different levels of sophistication. We will see that Schenck's book offers an interesting path into this wonderful subject. 1. What is algebraic ge...

3 Abstract Configurations in Algebraic Geometry

An abstract (vk, br)-configuration is a pair of finite sets of cardinalities v and b with a relation on the product of the sets such that each element of the first set is related to the same number k of elements from the second set and, conversely, each element of the second set is related to the same number r of elements in the first set. An example of an abstract configuration is a finite geo...

Applications of Some Properties of the Canonical Module in Computational Projective Algebraic Geometry

Introduction. The aim of this article is to show how one may use interesting properties of the canonical module for computational applications. It seems that the ideas we develop here are not used in computational algebraic geometry today. We do not claim any major improvement on the theoretical complexity of the problems we address, however we have the feeling that this alternative approach fo...
