Contractive Idempotents on Locally Compact Quantum Groups
[OWP201219] (Mathematisches Forschungsinstitut Oberwolfach, 2012)A general form of contractive idempotent functionals on coamenable locally compact quantum groups is obtained, generalising the result of Greenleaf on contractive measures on locally compact groups. The image of a convolution ... 
Control of Volterra systems with scalar kernels
[OWP200916] (Mathematisches Forschungsinstitut Oberwolfach, 20090310)Volterra observations systems with scalar kernels are studied. New sufficient conditions for admissibility of observation operators are developed and some examples are discussed.

0605  Convex and Algebraic Geometry
[OWR20065] (2006)  (29 Jan  04 Feb 2006)The subjects of convex and algebraic geometry meet primarily in the theory of toric varieties. Toric geometry is the part of algebraic geometry where all maps are given by monomials in suitable coordinates, and all equations ... 
0949  Convex Geometry and its Applications
[OWR200953] (2009)  (29 Nov  05 Dec 2009)The geometry of convex domains in Euclidean space plays a central role in several branches of mathematics: functional and harmonic analysis, the theory of PDE, linear programming and, increasingly, in the study of other ... 
1550  Convex Geometry and its Applications
[OWR201556] (2015)  (06 Dec  12 Dec 2015)The past 30 years have not only seen substantial progress and lively activity in various areas within convex geometry, e.g., in asymptotic geometric analysis, valuation theory, the $L_p$BrunnMinkowski theory and stochastic ...

1744b  Copositivity and Complete Positivity
[OWR201752] (2017)  (29 Oct  04 Nov 2017)A real matrix $A$ is called copositive if $x^TAx \ge 0$ holds for all $x \in \mathbb R^n_+$. A matrix $A$ is called completely positive if it can be factorized as $A = BB^T$ , where $B$ is an entrywise nonnegative matrix. ... 
1516b  Copulae: On the Crossroads of Mathematics and Economics
[OWR201520] (2015)  (12 Apr  18 Apr 2015)The central focus of the workshop was on copula theory as well as applications to multivariate stochastic modelling. The programme was intrinsically interdisciplinary and represented areas with much recent progress. The ... 
1143a  Correlations and Interactions for Random Quantum Systems
[OWR201150] (2011)  (23 Oct  29 Oct 2011)Random quantum systems cover a broad range of mathematical models from random Schr¨odinger operators to random matrices and quantum spin models with random parameters. Their understanding requires techniques which combine ... 
Counting Curves on Toric Surfaces Tropical Geometry & the Fock Space
[OWP201718] (Mathematisches Forschungsinstitut Oberwolfach, 20170717)We study the stationary descendant Gromov–Witten theory of toric surfaces by combining and extending a range of techniques – tropical curves, floor diagrams, and Fock spaces. A correspondence theorem is established between ... 
Counting selfavoiding walks on the hexagonal lattice
[SNAP2019006EN] (Mathematisches Forschungsinstitut Oberwolfach, 20190604)In how many ways can you go for a walk along a lattice grid in such a way that you never meet your own trail? In this snapshot, we describe some combinatorial and statistical aspects of these socalled selfavoiding ...

Criteria for Algebraicity of Analytic Functions
[OWP201825] (Mathematisches Forschungsinstitut Oberwolfach, 20181112)We consider functions defined on an open subset of a nonsingular, either real or complex, algebraic set. We give criteria for an analytic function to be a Nash (resp. regular, resp. polynomial) function. Our criteria depend ... 
Cryptanalysis of Publickey Cryptosystems Based on Algebraic Geometry Codes
[OWP201201] (Mathematisches Forschungsinstitut Oberwolfach, 20120320)This paper addresses the question of retrieving the triple $(\mathcal{X},\mathcal{P},\mathcal{E})$ from the algebraic geometry code $\mathcal{C}_L(\mathcal{X},\mathcal{P},\mathcal{E})$, where $\mathcal{X}$ is an algebraic ...
