A 3local characterization of Co2
[OWP200811] (Mathematisches Forschungsinstitut Oberwolfach, 20080315)Conway’s second largest simple group, $Co_2$, is characterized by the centralizer of an element of order 3 and certain fusion data. 
A 3local identification of the alternating group of degree 8, the McLaughlin simple group and their automorphism groups
[OWP200702] (Mathematisches Forschungsinstitut Oberwolfach, 20070320)In this article we give 3local characterizations of the alternating and symmetric groups of degree 8 and use these characterizations to recognize the sporadic simple group discovered by McLaughlin from its 3local subgroups. 
4 = 2 × 2, or the Power of Even Integers in Fourier Analysis
[SNAP2023006EN] (Mathematisches Forschungsinstitut Oberwolfach, 20231230)We describe how simple observations related to vectors of length 1 recently led to the proof of an important mathematical fact: the sharp Stein–Tomas inequality from Fourier restriction theory, a pillar of modern harmonic ...

[TB200128] (2001)  (01 Jul  07 Jul 2001) 
75 Jahre  Festschrift zum Jubiläum
(Mathematisches Forschungsinstitut Oberwolfach, 2022)The Festschrift that marks the 75th anniversary of the MFO in July 2019 includes many interesting contributions, documents and pictures. We would like to put your special focus on the lecture of Stefan Müller (Universität ... 
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 ... 
Abundance of 3Planes on Real Projective Hypersurfaces
[OWP201414] (Mathematisches Forschungsinstitut Oberwolfach, 20141111)We show that a generic real projective ndimensional hypersurface of odd degree $d$, such that $4(n2)=\binom{d+3}{3}$, contains "many" real 3planes, namely, in the logarithmic scale their number has the same rate of ... 
1036  Actions and Invariants of Residually Finite Groups: Asymptotic Methods
[OWR201040] (2010)  (05 Sep  11 Sep 2010)The workshop brought together experts in finite group theory, L2cohomology, measured group theory, the theory of lattices in Lie groups, probability and topology. The common object of interest was residually finite groups, ... 
1638a  Adaptive Algorithms
[OWR201644] (2016)  (18 Sep  24 Sep 2016)Overwhelming empirical evidence in computational science and engineering proved that selfadaptive meshgeneration is a mustdo in reallife problem computational partial differential equations. The mathematical understanding ... 
The adaptive finite element method
[SNAP2016013EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)Computer simulations of many physical phenomena rely on approximations by models with a finite number of unknowns. The number of these parameters determines the computational effort needed for the simulation. On the other ...

1207  Advanced Computational Engineering
[OWR20129] (2012)  (12 Feb  18 Feb 2012)The finite element method is the established simulation tool for the numerical solution of partial differential equations in many engineering problems with many mathematical developments such as mixed finite element methods ... 
AeppliBottChernMassey Products, Bigraded Notions of Formality, and NonZero Degree Maps
[OWP202204] (Mathematisches Forschungsinstitut Oberwolfach, 20220215)We introduce and study notions of bigraded formality for the algebra of forms on a complex manifold, along with their relation to higher AeppliBottChernMassey products which extend, in an augmented setting, the case of ...

Affine Space Fibrations
[OWP201819] (Mathematisches Forschungsinstitut Oberwolfach, 20180905)We discuss various aspects of affine space fibrations. Our interest will be focused in the singular fibers, the generic fiber and the propagation of properties of a given smooth special fiber to nearby fibers. 
Alexander rTuples and Bier Complexes
[OWP201617] (Mathematisches Forschungsinstitut Oberwolfach, 201610)We introduce and study Alexander $r$Tuples $\mathcal{K} = \langle K_i \rangle ^r_{i=1}$ of simplicial complexes, as a common generalization of pairs of Alexander dual complexes (Alexander 2tuples) and runavoidable ... 
The algebra of differential operators for a Gegenbauer weight matrix
[OWP201507] (Mathematisches Forschungsinstitut Oberwolfach, 20150729)In this work we study in detail the algebra of differential operators $\mathcal{D}(W)$ associated with a Gegenbauer matrix weight. We prove that two second order operators generate the algebra, indeed $\mathcal{D}(W)$ is ...
