Scaling limits and models in physical processes
[OWS28] (Birkhäuser Basel, 1998) 
Second Main Theorems and Unicity of Meromorphic Mappings with Moving Hypersurfaces
[OWP201138] (Mathematisches Forschungsinstitut Oberwolfach, 2011)In this article, we establish some new second main theorems for meromorphic mappings of $\mathbf{C}^m$ into $\mathbf{P}^n(\mathbf{C})$ and moving hypersurfaces with truncated counting functions. As an application, we prove ... 
Secondary heat flow between confocal ellipses: an application of extended thermodynamics
[OWP200711] (Mathematisches Forschungsinstitut Oberwolfach, 20070327)Much as nonNewtonian fluids exhibit secondary flows in elliptic pipes, rarefied gases exhibit secondary heat flows between elliptical cylinders. The phenomenon may be called nonFourierian, because it is not covered by ... 
Selfadjoint differentialalgebraic equations
[OWP201127] (Mathematisches Forschungsinstitut Oberwolfach, 20110524)Motivated from linearquadratic optimal control problems for differentialalgebraic equations (DAEs), we study the functional analytic properties of the operator associated with the necessary optimality boundary value ... 
Selfdual polygons and selfdual curves
[OWP200709] (Mathematisches Forschungsinstitut Oberwolfach, 20070325) 
SemiInvertible Extensions of C*Algebras
[OWP201017] (Mathematisches Forschungsinstitut Oberwolfach, 20100317)We prolonge the list of $C^*$algebras for which all extensions by any stable separable $C^*$algebra are semiinvertible. In particular, we handle certain amalgamations, both of $C^*$algebras and of groups. Concerning ... 
Seminar on empirical processes
(Birkhäuser Basel, 1987) 
A series of algebras generalizing the Octonions and HurwitzRadon Identity
[OWP201010] (Mathematisches Forschungsinstitut Oberwolfach, 2010)We study nonassociative 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 ... 
Shape Theory and Extensions of C*Algebras
[OWP201016] (Mathematisches Forschungsinstitut Oberwolfach, 20100316)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 JohnNirenberg inequality
[OWP201307] (Mathematisches Forschungsinstitut Oberwolfach, 20130314)The sharp constants in the classical JohnNirenberg inequality are found by using Bellman function approach. 
A short story on optimal transport and its many applications
[SNAP2018013EN] (Mathematisches Forschungsinstitut Oberwolfach, 20180808)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
[OWP200912] (Mathematisches Forschungsinstitut Oberwolfach, 20090306)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
[OWP200920] (Mathematisches Forschungsinstitut Oberwolfach, 20090313)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
[OWP201518] (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. ... 
Singer quadrangles
[OWP200907] (Mathematisches Forschungsinstitut Oberwolfach, 20090301) 
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 ... 
Solid extensions of the Cesàro operator on the Hardy space H2(D)
[OWP201311] (Mathematisches Forschungsinstitut Oberwolfach, 20130423)We introduce and study the largest Banach space of analytic functions on the unit disc which is solid for the coefficientwise order and to which the classical Ces`aro operator $\mathcal{C}:H^2 \to H^2$ can be continuously ... 
Solving quadratic equations in many variables
[SNAP2017012EN] (Mathematisches Forschungsinstitut Oberwolfach, 20171230)Fields are number systems in which every linear equation has a solution, such as the set of all rational numbers $\mathbb{Q}$ or the set of all real numbers $\mathbb{R}$. All fields have the same properties in relation ... 
Some Combinatorial Identities Related to Commuting Varieties and Hilbert Schemes
[OWP201102] (Mathematisches Forschungsinstitut Oberwolfach, 2011)In this article we explore some of the combinatorial consequences of recent results relating the isospectral commuting variety and the Hilbert scheme of points in the plane. 
Some Results on Reducibility of Parabolic Induction for Classical Groups
[OWP201709] (Mathematisches Forschungsinstitut Oberwolfach, 20170330)Given a (complex, smooth) irreducible representation $\pi$ of the general linear group over a nonarchimedean local field and an irreducible supercuspidal representation $\sigma$ of a classical group, we show that ...
