Combinatorial Aspects of Commutative Algebra and Algebraic Geometry

The Abel Symposium 2009 "Combinatorial aspects of Commutative Algebra and Algebraic Geometry", held at Voss, Norway, featured talks by leading researchers in the field. This is the proceedings of the Symposium, presenting contributions on syzygies, tropical geometry, Boij-Söderberg theory, Schubert calculus, and quiver varieties. The volume also includes an introductory survey on binomial ideals with applications to hypergeometric series, combinatorial games and chemical reactions. The contributions pose interesting problems, and offer up-to-date research on some of the most active fields of commutative algebra and algebraic geometry with a combinatorial flavour.

Contains contributions on syzygies, Boij-Söderberg theory, tropical geometry, Schubert calculus, and quiver varieties Contains an introductory survey by E.Miller on binomial ideals and their applications to hypergeometric series, combinatorial games and chemical reactions Contributions by leading researchers on topics in commutative algebra and algebraic geometry related to combinatorics Includes supplementary material: sn.pub/extras

Auteur
Gunnar Fløystad has published on topics in algebraic geometry, combinatorial commutative algebra and non-commutative algebra. Trygve Johnsen has published in algebraic geometry and coding theory, and is also interested in relations to matroids. Andreas Leopold Knutsen has published in algebraic geometry, especially in geometry of curves and surfaces, and in birational geometry.
