Alternative iterative methods for nonexpansive mappings, rates of convergence and applications
[OWP200919] (Mathematisches Forschungsinstitut Oberwolfach, 2009)Alternative iterative methods for a nonexpansive mapping in a Banach space are proposed and proved to be convergent to a common solution to a fixed point problem and a variational inequality. We give rates of asymptotic ...

1414  Arbeitsgemeinschaft: Superrigidity
[OWR201416] (2014)  (30 Mar  05 Apr 2014)The purpose of the Arbeitsgemeinschaft was to review old and new phenomenas of rigidity in mathematics. The broad spectrum of such results was covered, such as MargulisZimmer superrigidity, cocyle and character rigidity. 
Boundary Representations of Operator Spaces, and Compact Rectangular Matrix Convex Sets
[OWP201624] (Mathematisches Forschungsinstitut Oberwolfach, 20161213)We initiate the study of matrix convexity for operator spaces. We define the notion of compact rectangular matrix convex set, and prove the natural analogs of the KreinMilman and the bipolar theorems in this context. We ... 
2050  Computational Inverse Problems for Partial Differential Equations (hybrid meeting)
[OWR202039] (2020)  (06 Dec  12 Dec 2020)Inverse problems in partial differential equations (PDEs) consist in reconstructing some part of a PDE such as a coefficient, a boundary condition, an initial condition, the shape of a domain, or a singularity from ... 
Convolution in Dual Cesàro Sequence Spaces
[OWP202220] (Mathematisches Forschungsinstitut Oberwolfach, 20221216)We investigate convolution operators in the sequence spaces $d_p$, for 1 $\leqslant p<\infty$. These spaces, for $p$ > 1, arise as dual spaces of the Cesàro sequence spaces $ces_p$ thoroughly investigated by G. Bennett. A ...
