• #### A Quantitative Analysis of the “Lion-Man” Game ﻿

[OWP-2019-18] (Mathematisches Forschungsinstitut Oberwolfach, 2019-07-08)
In this paper we analyze, based on an interplay between ideas and techniques from logic and geometric analysis, a pursuit-evasion game. More precisely, we focus on a discrete lion and man game with an $\varepsilon$-capture ...
• #### Quantities that frequency-dependent selection maximizes ﻿

[OWP-2008-18] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-18)
We consider a model of frequency-dependent selection, to which we refer as the Wildcard Model, that accommodates as particular cases a number of diverse models of biologically specific situations. Two very different ...
• #### Quantum diffusion ﻿

[SNAP-2015-014-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
If you place a drop of ink into a glass of water, the ink will slowly dissipate into the surrounding water until it is perfectly mixed. If you record your experiment with a camera and play the film backwards, you will see ...
• #### Quotients of Index Two and General Quotients in a Space of Orderings ﻿

[OWP-2011-36] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-30)
In this paper we investigate quotient structures and quotient spaces of a space of orderings arising from subgroups of index two. We provide necessary and sufficient conditions for a quotient structure to be a quotient ...
• #### Random dynamics of transcendental functions ﻿

[OWP-2014-12] (Mathematisches Forschungsinstitut Oberwolfach, 2014-08-20)
This work concerns random dynamics of hyperbolic entire and meromorphic functions of finite order and whose derivative satisfies some growth condition at infinity. This class contains most of the classical families of ...
• #### 1118 - Random Matrices, Geometric Functional Analysis and Algorithms ﻿

[OWR-2011-24] (2011) - (01 May - 07 May 2011)

• #### Random permutations ﻿

[SNAP-2019-007-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-07-12)
100 people leave their hats at the door at a party and pick up a completely random hat when they leave. How likely is it that at least one of them will get back their own hat? If the hats carry name tags, how difficult ...
• #### Random sampling of domino and lozenge tilings ﻿

[SNAP-2016-002-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
A grid region is (roughly speaking) a collection of “elementary cells” (squares, for example, or triangles) in the plane. One can “tile” these grid regions by arranging the cells in pairs. In this snapshot we review different ...
• #### 0904 - Random Trees ﻿

[OWR-2009-3] (2009) - (18 Jan - 24 Jan 2009)
The meeting was devoted to random trees, a central concept in mathematics that provides a key way of thinking about relationships between objects such as particles in a ﬂuid, individuals in a population, or labels in a ...
• #### Rate of Convergence of the Density Estimation of Regression Residual ﻿

[OWP-2012-08] (Mathematisches Forschungsinstitut Oberwolfach, 2012)
