Abstract Bivariant Cuntz Semigroups
[OWP201704] (Mathematisches Forschungsinstitut Oberwolfach, 20170213)We show that abstract Cuntz semigroups form a closed symmetric monoidal category. Thus, given Cuntz semigroups $S$ and $T$, there is another Cuntz semigroup $((S,T))$ playing the role of morphisms from $S$ to $T$. Applied ... 
0629  Algebraic KTheory
[OWR200632] (2006)  (16 Jul  22 Jul 2006)This is the report on the Oberwolfach workshop Algebraic KTheory, held in July 2006. The talks covered mainly topics from Algebraic Geometry and Number Theory in connection with KTheory. Special emphasis was placed on ... 
1926  Algebraic Ktheory
[OWR201929] (2019)  (23 Jun  29 Jun 2019)Algebraic $K$theory has seen a fruitful development during the last three years. Part of this recent progress was driven by the use of $\infty$categories and related techniques originally developed in algebraic ... 
2219  Algebraic KTheory
[OWR202224] (2022)  (08 May  14 May 2022)Algebraic $K$theory has seen further progress during the last three years. One important aspect of this recent progress has been a better conceptual understanding of motivic filtrations on $K$theory and the systematic ... 
1626  Algebraic Ktheory and Motivic Cohomology
[OWR201631] (2016)  (26 Jun  02 Jul 2016)Algebraic $K$theory and motivic cohomology have developed together over the last thirty years. Both of these theories rely on a mix of algebraic geometry and homotopy theory for their construction and development, and ... 
1326  Algebraic Ktheory and Motivic Cohomology
[OWR201332] (2013)  (23 Jun  29 Jun 2013)Algebraic Ktheory and motivic cohomology are strongly related tools providing a systematic way of producing invariants for algebraic or geometric structures. The definition and methods are taken from algebraic topology, ... 
0927  Algebraic KTheory and Motivic Cohomology
[OWR200931] (2009)  (28 Jun  04 Jul 2009)Algebraic Ktheory and the related motivic cohomology are a systematic way of producing invariants for algebraic or geometric structures. Its deﬁnition and methods are taken from algebraic topology, but it has also proved ... 
1428  Algebraische Zahlentheorie
[OWR201432] (2014)  (06 Jul  12 Jul 2014)The workshop brought together leading experts in Algebraic Number Theory. The talks presented new methods and results that intertwine a multitude of topics ranging from classical diophantine themes to modern arithmetic ... 
1732  Analysis, Geometry and Topology of Positive Scalar Curvature Metrics
[OWR201736] (2017)  (06 Aug  12 Aug 2017)Riemannian manifolds with positive scalar curvature play an important role in mathematics and general relativity. Obstruction and existence results are connected to index theory, bordism theory and homotopy theory, using ... 
1432  Analysis, Geometry and Topology of Positive Scalar Curvature Metrics
[OWR201436] (2014)  (03 Aug  09 Aug 2014)One of the fundamental problems in Riemannian geometry is to understand the relation of locally defined curvature invariants and global properties of smooth manifolds. This workshop was centered around the investigation ... 
2126a  Analysis, Geometry and Topology of Positive Scalar Curvature Metrics (hybrid meeting)
[OWR202130] (2021)  (27 Jun  03 Jul 2021)The investigation of Riemannian metrics with lower scalar curvature bounds has been a central topic in differential geometry for decades. It addresses foundational problems, combining ideas and methods from global analysis, ...

[OWR200646] (2006)  (08 Oct  14 Oct 2006)The “Arbeitsgemeinsschaft mit aktuellem Thema ‘Twisted KTheory’ ” gave an introduction to several aspects of twisted Ktheory. It started with a couple of different definitions of twisted Ktheory, suitable in situations ... 
1814  Arbeitsgemeinschaft: Topological Cyclic Homology
[OWR201815] (2018)  (01 Apr  07 Apr 2018)Introduced by BökstedtHsiangMadsen in the nineties, topological cyclic homology is a manifestation of the dual visions of ConnesTsygan and Waldhausen to extend de Rham cohomology to a noncommutative setting and to ...
