• #### Totally Acyclic Complexes ﻿

[OWP-2016-14] (Mathematisches Forschungsinstitut Oberwolfach, 2016-08-17)
We prove first (Proposition 3) that, over any ring $R$, an acyclic complex of projective modules is totally acyclic if and only if the cycles of every acyclic complex of Gorenstein projective modules are Gorenstein projective. ...
• #### Touching the transcendentals: tractional motion from the bir th of calculus to future perspectives ﻿

[SNAP-2019-013-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-11-21)
When the rigorous foundation of calculus was developed, it marked an epochal change in the approach of mathematicians to geometry. Tools from geometry had been one of the foundations of mathematics until the 17th century ...
• #### Towards a Mathematical Theory of Turbulence in Fluids ﻿

[SNAP-2016-015-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
Fluid mechanics is the theory of how liquids and gases move around. For the most part, the basic physics are well understood and the mathematical models look relatively simple. Despite this, fluids display a dazzling mystery ...

[OWR-2011-7] (2011) - (30 Jan - 05 Feb 2011)
Motivated both by industrial applications and the challenge of new problems, one observes an increasing interest in the field of image and surface processing over the last years. It has become clear that even though the ...
• #### 0704 - Trends in Mathematical Imaging and Surface Processing ﻿

[OWR-2007-3] (2007) - (21 Jan - 27 Jan 2007)
Motivated both by industrial applications and the challenge of new problems, one observes an increasing interest in the field of image and surface processing over the last years. It has become clear that even though the ...
• #### 1218 - Triangulations ﻿

[OWR-2012-24] (2012) - (29 Apr - 05 May 2012)
The earliest work in topology was often based on explicit combinatorial models – usually triangulations – for the spaces being studied. Although algebraic methods in topology gradually replaced combinatorial ones in the ...
• #### Tropical Algebraic Geometry ﻿

[OWS-35] (Birkhäuser Basel, 2007)
Tropical geometry is algebraic geometry over the semifield of tropical numbers, i.e., the real numbers and negative infinity enhanced with the (max,+)-arithmetics. Geometrically, tropical varieties are much simpler than ...
• #### 1518 - Tropical Aspects in Geometry, Topology and Physics ﻿

[OWR-2015-23] (2015) - (26 Apr - 02 May 2015)
The workshop Tropical Aspects in Geometry, Topology and Physics was devoted to a wide discussion and exchange of ideas between the leading experts representing various points of view on the subject. The development of ...
• #### Tropical geometry ﻿

[SNAP-2018-007-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2018-07-19)
What kind of strange spaces hide behind the enigmatic name of tropical geometry? In the tropics, just as in other geometries, one of the simplest objects is a line. Therefore, we begin our exploration by considering tropical ...
• #### 0750 - Tropical Geometry ﻿

[OWR-2007-57] (2007) - (09 Dec - 15 Dec 2007)
Tropical Geometry is a new and rapidly developing discipline that touches upon many branches of modern mathematics. It is characterized by the transition of algebro-geometric objects to piecewise-linear ones, thereby ...
• #### 1918 - Tropical Geometry: new directions ﻿

[OWR-2019-21] (2019) - (28 Apr - 04 May 2019)
The workshop "Tropical Geometry: New Directions" was devoted to a wide discussion and exchange of ideas between the leading experts representing various points of view on the subject, notably, to new phenomena that have ...
• #### The Tutte Polynomial of Ideal Arrangements ﻿

[OWP-2018-28] (Mathematisches Forschungsinstitut Oberwolfach, 2018-12-21)
The Tutte polynomial is originally a bivariate polynomial enumerating the colorings of a graph and of its dual graph. But it reveals more of the internal structure of the graph like its number of forests, of spanning ...
• #### 0125b - Two Hundred Years of Number Theory after Carl-Friedrich Gauß's Disquisitiones Arithmeticae ﻿

[TB-2001-26] (2001) - (17 Jun - 23 Jun 2001)
• #### 1911 - Uncertainty Quantification ﻿

[OWR-2019-12] (2019) - (10 Mar - 16 Mar 2019)
Uncertainty quantification (UQ) is concerned with including and characterising uncertainties in mathematical models. Major steps comprise proper description of system uncertainties, analysis and efficient quantification ...

[OWR-2013-49] (2013) - (29 Sep - 05 Oct 2013)
The topics of the workshop were recent progress in the theory of uniform distribution theory (also known as discrepancy theory) and new developments in its applications in analysis, approximation theory, computer science, ...
• #### A Uniform Model for Kirillov-Reshetikhin Crystals I: Lifting the Parabolic Quantum Bruhat Graph ﻿

[OWP-2012-18] (Mathematisches Forschungsinstitut Oberwolfach, 2012)
We consider two lifts of the parabolic quantum Bruhat graph, one into the Bruhat order in the affine Weyl group and the other into a level-zero weight poset first considered by Littelmann. The lift into the affine Weyl ...
• #### Upper bounds for the number of solutions to quartic thue equations ﻿
