• #### Semi-Invertible Extensions of C*-Algebras ﻿

[OWP-2010-17] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-17)
We prolonge the list of $C^*$-algebras for which all extensions by any stable separable $C^*$-algebra are semi-invertible. In particular, we handle certain amalgamations, both of $C^*$-algebras and of groups. Concerning ...
• #### Seminar on empirical processes ﻿

[OWS-09] (Birkhäuser Basel, 1987)
• #### Seminar on geometrical measure theory ﻿

[OWS-07] (Birkhäuser Basel, 1986)
• #### 0712 - Semiparametric and Nonparametric Methods in Econometrics ﻿

[OWR-2007-15] (2007) - (18 Mar - 24 Mar 2007)
The main objective of this workshop was to bring together mathematical statisticians and econometricians who work in the field of nonparametric and semiparametric statistical methods. Nonparametric and semiparametric methods ...
• #### A series of algebras generalizing the Octonions and Hurwitz-Radon Identity ﻿

[OWP-2010-10] (Mathematisches Forschungsinstitut Oberwolfach, 2010)
We study non-associative twisted group algebras over $(\mathbb{Z}_2)^n$ with cubic twisting functions. We construct a series of algebras that extend the classical algebra of octonions in the same way as the Clifford algebras ...
• #### 0549 - Set Theory ﻿

[OWR-2005-55] (2005) - (04 Dec - 10 Dec 2005)
This meeting covered all important aspects of modern Set Theory, including large cardinal theory, combinatorial set theory, descriptive set theory, connections with algebra and analysis, forcing axioms and inner model ...
• #### 1102 - Set Theory ﻿

[OWR-2011-2] (2011) - (09 Jan - 15 Jan 2011)
This stimulating workshop exposed some of the most exciting recent develops in set theory, including major new results about the proper forcing axiom, stationary reflection, gaps in P(ω)/Fin, iterated forcing, the tree ...
• #### 0803 - Set Theory ﻿

[OWR-2008-2] (2008) - (13 Jan - 19 Jan 2008)
• #### 1403 - Set Theory ﻿

[OWR-2014-2] (2014) - (12 Jan - 18 Jan 2014)
This stimulating workshop featured a broad selection of some of the most important recent developments in combinatorial set theory, the theory and applications of forcing, large cardinal theory and descriptive set theory.
• #### 1707 - Set Theory ﻿

[OWR-2017-11] (2017) - (12 Feb - 18 Feb 2017)
This workshop included selected talks on pure set theory and its applications, simultaneously showing diversity and coherence of the subject.
• #### Shape Theory and Extensions of C*-Algebras ﻿

[OWP-2010-16] (Mathematisches Forschungsinstitut Oberwolfach, 2010-03-16)
Let A, A' be separable $C^*$-algebras, $B$ a stable $\sigma$-unital $C^*$-algebra. Our main result is the construction of the pairing $[[A', A]] \times Ext^{-1/2}(A,B) \to Ext^{-1/2}(A',B)$, where $[[A', A]]$ denotes the ...
• #### Sharp constants in the classical weak form of the John-Nirenberg inequality ﻿

[OWP-2013-07] (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)
The sharp constants in the classical John-Nirenberg inequality are found by using Bellman function approach.
• #### A short story on optimal transport and its many applications ﻿

[SNAP-2018-013-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2018-08-08)
We present some examples of optimal transport problems and of applications to different sciences (logistics, economics, image processing, and a little bit of evolution equations) through the crazy story of an industrial ...
• #### Simple graded commutative algebras ﻿

[OWP-2009-12] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-06)
We study the notion of $\Gamma$-graded commutative algebra for an arbitrary abelian group $\Gamma$. The main examples are the Clifford algebras already treated in [2]. We prove that the Clifford algebras are the only ...
• #### Simple vector bundles on plane degenerations of an elliptic curve ﻿

[OWP-2009-20] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-13)
In 1957 Atiyah classified simple and indecomposable vector bundles on an elliptic curve. In this article we generalize his classification by describing the simple vector bundles on all reduced plane cubic curves. Our main ...
• #### Simulation of Multibody Systems with Servo Constraints through Optimal Control ﻿

[OWP-2015-18] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We consider mechanical systems where the dynamics are partially constrained to prescribed trajectories. An example for such a system is a building crane with a load and the requirement that the load moves on a certain path. ...
