Supertropical semirings and supervaluations
[OWP201005] (Mathematisches Forschungsinstitut Oberwolfach, 2010)We interpret a valuation $\upsilon$ on a ring $R$ as a map $\upsilon:R \rightarrow M$ into a so called bipotent semiring $M$ (the usual maxplus setting), and then define a supervaluation $\varphi$ as a suitable map into ... 
Sur le Minimum de la Fonction de Brjuno
[OWP201826] (Mathematisches Forschungsinstitut Oberwolfach, 20181211)The Brjuno function attains a strict global minimum at the golden section. 
1649  Surface Bundles
[OWR201656] (2016)  (04 Dec  10 Dec 2016)This workshop brought together specialists in algebraic topology, low dimensional topology, geometric group theory, algebraic geometry and neighboring fields. It provided a good overview of the current developments, and ... 
1904  Surface, Bulk, and Geometric Partial Differential Equations: Interfacial, stochastic, nonlocal and discrete structures
[OWR20193] (2019)  (20 Jan  26 Jan 2019)Partial differential equations in complex domains with free\linebreak boundaries and interfaces continue to be flourishing research areas at the interfaces between PDE theory, differential geometry, numerical analysis ... 
Surgery theory and geometry of representations
[OWS11] (Birkhäuser Basel, 1988)These notes were prepared for the DMVSeminar held in Dusseldorf, Schloss Mickeln from June 28 to July 5, 1987. They consist of two parts which can be read independently. The reader is presumed to have a basic education ... 
A surprising connection between quantum mechanics and shallow water waves
[SNAP2019018EN] (Mathematisches Forschungsinstitut Oberwolfach, 20191211)We describe a connection between quantum mechanics and nonlinear wave equations and highlight a few problems at the forefront of modern research in the intersection of these areas. 
Swallowtail on the shore
[SNAP2014007EN] (Mathematisches Forschungsinstitut Oberwolfach, 2014)Platonic solids, Felix Klein, H.S.M. Coxeter and a flap of a swallowtail: The five Platonic solids tetrahedron, cube, octahedron, icosahedron and dodecahedron have always attracted much curiosity from mathematicians, not ... 
Swarming robots
[SNAP2016001EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)When lots of robots come together to form shapes, spread in an area, or move in one direction, their motion has to be planned carefully. We discuss how mathematicians devise strategies to help swarms of robots behave like ... 
The Sylow Structure of Scalar Automorphism Groups
[OWP201805] (Mathematisches Forschungsinstitut Oberwolfach, 20180322)For any locally compact abelian periodic group A its automorphism group contains as a subgroup those automorphisms that leave invariant every closed subgroup of A, to be denoted by SAut(A). This subgroup is again a locally ... 
Symmetry and characters of finite groups
[SNAP2016005EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)Over the last two centuries mathematicians have developed an elegant abstract framework to study the natural idea of symmetry. The aim of this snapshot is to gently guide the interested reader through these ideas. In ... 
The TGraph of a Multigraded Hilbert Scheme
[OWP201134] (Mathematisches Forschungsinstitut Oberwolfach, 2011)The $T$graph of a multigraded Hilbert scheme records the zero and onedimensional orbits of the $T=(K^*)^n$ action on the Hilbert scheme induced from the $T$action on $\mathbb{A}^n$. It has vertices the $T$fixed points, ... 
A tale of three curves
[SNAP2022010EN] (Mathematisches Forschungsinstitut Oberwolfach, 20221027)In this snapshot, we give a survey of some problems in the study of rational points on higher genus curves, discussing questions ranging from the era of the ancient Greeks to a few posed by mathematicians of the 20th ...

Ten lectures on random media
[OWS32] (Birkhäuser Basel, 2002)The following notes grew out oflectures held during the DMVSeminar on Random Media in November 1999 at the Mathematics Research Institute of Oberwolfach, and in FebruaryMarch 2000 at the Ecole Normale Superieure in Paris. ... 
Tensor Representations of q(∞)
[OWP201609] (Mathematisches Forschungsinstitut Oberwolfach, 20160617)We introduce a symmetric monoidal category of modules over the direct limit queer superalgebra $\mathfrak{q}(\infty)$. The category can be defined in two equivalent ways with the aid of the large annihilator condition. ... 
The ternary Goldbach problem
[SNAP2014003EN] (Mathematisches Forschungsinstitut Oberwolfach, 2014)Leonhard Euler (1707–1783) – one of the greatest mathematicians of the eighteenth century and of all times – often corresponded with a friend of his, Christian Goldbach (1690–1764), an amateur and polymath who lived and ... 
Das ternäre GoldbachProblem
[SNAP2014003DE] (Mathematisches Forschungsinstitut Oberwolfach, 2020)Leonhard Euler (1707–1783) war einer der besten Mathematiker des 18. Jahrhunderts und wohl auch aller Zeiten. Er korrespondierte oft mit seinem Freund, Christoph Goldbach (1690–1764), einem Universalgelehrten, der auch ...
