• 1650 - Asymptotic Phenomena in Local Algebra and Singularity Theory 

      [OWR-2016-57] Workshop Report 2016,57 (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 ...
    • 1631 - Computational Group Theory 

      [OWR-2016-37] Workshop Report 2016,37 (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 ...
    • 1643 - Definability and Decidability Problems in Number Theory 

      [OWR-2016-49] Workshop Report 2016,49 (2016) - (23 Oct - 29 Oct 2016)
      This workshop brought together experts working on variations of Hilbert’s Tenth Problem and more general decidability issues for structures other than the ring of integers arising naturally in number theory and algebraic geometry.
    • 1607b - Hochschild Cohomology in Algebra, Geometry, and Topology 

      [OWR-2016-10] Workshop Report 2016,10 (2016) - (14 Feb - 20 Feb 2016)
      In 1945 Gerhard Hochschild published "On the cohomology groups of an associative algebra" in the Annals of Mathematics and thereby created what is now called Hochschild theory. In 1963, Murray Gerstenhaber proved that the ...
    • 1609b - Mini-Workshop: Arrangements of Subvarieties, and their Applications in Algebraic Geometry 

      [OWR-2016-14] Workshop Report 2016,14 (2016) - (28 Feb - 05 Mar 2016)
      While arrangements of hyperplanes have been studied in algebra, combinatorics and geometry for a long time, recent discoveries suggest that they (and more generally arrangements of nonlinear subvarieties) play an even more ...
    • 1651c - Mini-Workshop: Surreal Numbers, Surreal Analysis, Hahn Fields and Derivations 

      [OWR-2016-60] Workshop Report 2016,60 (2016) - (18 Dec - 23 Dec 2016)
      New striking analogies between H. Hahn’s fields of generalised series with real coefficients, G. H. Hardy’s field of germs of real valued functions, and J. H. Conway’s field No of surreal numbers, have been lately discovered ...
