• #### Positivity of the T-system cluster algebra ﻿

[OWP-2009-21] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-14)
We give the path model solution for the cluster algebra variables of the $A_r$ T-system with generic boundary conditions. The solutions are partition functions of (strongly) non-intersecting paths on weighted graphs. The ...
• #### A potential reduction algorithm for two-person zero-sum mean payoff stochastic games ﻿

[OWP-2015-19] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We suggest a new algorithm for two-person zero-sum undiscounted stochastic games focusing on stationary strategies. Given a positive real $\epsilon$, let us call a stochastic game $\epsilon$-ergodic, if its values from any ...
• #### Preconditioning of Block Tridiagonal Matrices ﻿

[OWP-2008-05] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-09)
Preconditioning methods via approximate block factorization for block tridiagonal matrices are studied. Bounds for the resulting condition numbers are given, and two methods for the recursive construction of the approximate ...
• #### Prediction and Quantification of Individual Athletic Performance ﻿

[OWP-2015-11] (Mathematisches Forschungsinstitut Oberwolfach, 2015-08-27)
We present a novel, quantitative view on the human athletic performance of individuals. We obtain a predictor for athletic running performances, a parsimonious model, and a training state summary consisting of three numbers, ...
• #### Prime tuples in function fields ﻿

[SNAP-2016-010-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
How many prime numbers are there? How are they distributed among other numbers? These are questions that have intrigued mathematicians since ancient times. However, many questions in this area have remained unsolved, and ...
• #### 0621 - Pro-p Extensions of Global Fields and pro-p Groups ﻿

[OWR-2006-25] (2006) - (21 May - 27 May 2006)
• #### 1521 - Probabilistic Techniques in Modern Statistics ﻿

[OWR-2015-26] (2015) - (17 May - 23 May 2015)
The aim of the workshop was to bring together researchers in modern probability theory and statistics to discuss recent advances and challenging open problems at the intersection of both fields. It focussed on the most ...
• #### 0211 - Probability and Statistics of Random Algebraic Structures ﻿

[TB-2002-14] (2002) - (10 Mar - 16 Mar 2002)

[OWR-2014-50] (2014) - (02 Nov - 08 Nov 2014)
The subject of this workshop were probabilistic aspects of algorithms for fundamental problems such as sorting, searching, selecting of and within data, random permutations, algorithms based on combinatorial trees or search ...
• #### Das Problem der Kugelpackung ﻿

[SNAP-2016-004-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
Wie würdest du Tennisbälle oder Orangen stapeln? Oder allgemeiner formuliert: Wie dicht lassen sich identische 3-dimensionale Objekte überschneidungsfrei anordnen? Das Problem, welches auch Anwendungen in der digitalen ...
• #### Products of pairs of Dehn twists and maximal real Lefschetz fibrations ﻿

[OWP-2011-32] (Mathematisches Forschungsinstitut Oberwolfach, 2011)
We address the problem of existence and uniqueness of a factorization of a given element of the modular group into a product of two Dehn twists. As a geometric application, we conclude that any maximal real elliptic ...

• #### Profinite groups ﻿

[SNAP-2016-014-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
Profinite objects are mathematical constructions used to collect, in a uniform manner, facts about infinitely many finite objects. We shall review recent progress in the theory of profinite groups, due to Nikolov and Segal, ...
