2139  Singularities (hybrid meeting)
[OWR202147] (2021)  (26 Sep  02 Oct 2021)Singularity theory concerns local and global structure of singularities of (algebraic) varieties and maps. As such, it combines tools from algebraic geometry, complex analysis, topology, algebra and combinatorics. 
Singularities and Bifurcations of Pseudospherical Surfaces
[OWP202008] (Mathematisches Forschungsinstitut Oberwolfach, 20200317)We study singularities and bifurcations of constant negative curvature surfaces in Euclidean 3space via their association with Lorentzian harmonic maps. This preprint presents the basic results on this, the full proofs ...

1907  Singularities and Homological Aspects of Commutative Algebra
[OWR20196] (2019)  (10 Feb  16 Feb 2019)Commutative algebra has recently witnessed a number of spectacular developments, resulting in the resolution of longstanding problems. The new techniques and perspectives, such as methods from the theory of perfectoid ... 
1217b  Singularity Theory and Integrable Systems
[OWR201223] (2012)  (22 Apr  28 Apr 2012)The workshop brought together three very different areas of mathematics, namely singularity theory, integrable systems and quantum cohomology. They are linked by their applications in topological quantum field theory and ... 
2309a  Skew Braces and the YangBaxter Equation
[OWR20239] (2023)  (26 Feb  04 Mar 2023)The workshop was focused on the interplay between settheoretic solutions to the YangBaxter equation and several algebraic structures used to construct and understand new solutions. In this vein, the YBE and properties ... 
Slowly oscillating wave solutions of a single species reactiondiffusion equation with delay
[OWP200712] (Mathematisches Forschungsinstitut Oberwolfach, 20070328)We study positive bounded wave solutions $u(t, x) = \phi(\nu \cdot x+ct)$, $\phi(\infty)=0$, of equation $u_t(t, x)=\delta u(t,x)−u(t,x) +g(u(t−h,x))$, $x \in \mathbb{R}^m$(*). It is supposed that Eq. (∗) has exactly two ...

[OWR202116] (2021)  (21 Mar  27 Mar 2021)The classical theory of electromagnetism describes the interaction of electrically charged particles through electromagnetic forces, which are carried by the electric and magnetic fields. The propagation of the electromagnetic ... 
Snake graphs, perfect matchings and continued fractions
[SNAP2019001EN] (Mathematisches Forschungsinstitut Oberwolfach, 20190213)A continued fraction is a way of representing a real number by a sequence of integers. We present a new way to think about these continued fractions using snake graphs, which are sequences of squares in the plane. You ...
