[OWR-2010-57] (2010) - (12 Dec - 18 Dec 2010)Polynomial vector fields are in the focus of research in various areas of mathematics and its applications. As a consequence, researchers from rather different disciplines work with polynomial vector fields. The main goal ... -
1609b - Mini-Workshop: Arrangements of Subvarieties, and their Applications in Algebraic Geometry
[OWR-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 ... -
1840b - Mini-Workshop: Asymptotic Invariants of Homogeneous Ideals
[OWR-2018-45] (2018) - (30 Sep - 06 Oct 2018)Recent decades have witnessed a shift in interest from isolated objects to families of objects and their limit behavior, both in algebraic geometry and in commutative algebra. A series of various invariants have been ... -
1810a - Mini-Workshop: Chromatic Phenomena and Duality in Homotopy Theory and Representation Theory
[OWR-2018-9] (2018) - (04 Mar - 10 Mar 2018)This mini-workshop focused on chromatic phenomena and duality as unifying themes in algebra, geometry, and topology. The overarching goal was to establish a fruitful exchange of ideas between experts from various areas, ... -
