[OWR200726] (2007)  (13 May  19 May 2007)Galois theory is the study of symmetries in solution spaces of polynomial and differential equations and more generally of the relation between automorphism groups (or group schemes respectively) and the structure of ... 
1650  Asymptotic Phenomena in Local Algebra and Singularity Theory
[OWR201657] (2016)  (11 Dec  17 Dec 2016)The goal of this workshop was to highlight, and further, the interactions between local algebra and singularity theory. The timing was serendipitous for both subjects have witnessed tremendous progress recently, much of ... 
1350  Cluster Algebras and Related Topics
[OWR201358] (2013)  (08 Dec  14 Dec 2013)Cluster algebras are a class of commutative algebras intoduced by Fomin and Zelevinsky in 2000. Their original purpose was to obtain a combinatorial approach to Lusztig’s dual canonical bases of quantum groups and to total ... 
1631  Computational Group Theory
[OWR201637] (2016)  (31 Jul  06 Aug 2016)This was the seventh workshop on Computational Group Theory. It showed that Computational Group Theory has significantly expanded its range of activities. For example, symbolic computations with groups and their representations ...
