• #### 1014 - Arbeitsgemeinschaft: Mathematical Billards ﻿

[OWR-2010-17] (2010) - (04 Apr - 10 Apr 2010)
The workshop Mathematical Billiards, organised by Serge Tabachnikov (Penn State) and Serge Troubetzkoy (Marseille) was held April 4th–April 10th, 2010. This meeting was well attended by over 40 participants including a ...
• #### 1123 - Arithmetic Groups vs. Mapping Class Groups: Similarities, Analogies and Differences ﻿

[OWR-2011-30] (2011) - (05 Jun - 11 Jun 2011)
Arithmetic groups arise naturally in many fields such as number theory, algebraic geometry, and analysis. Mapping class groups arise in both low dimensional topology and geometric group theory. They have been studied ...
• #### 1119 - Billiards, Flat Surfaces, and Dynamics on Moduli Spaces ﻿

[OWR-2011-25] (2011) - (08 May - 14 May 2011)
This workshop brought together people working on the dynamics of various flows on moduli spaces, in particular the action of SL$_2(\mathbb R)$ on flat surfaces. The new results presented covered properties of interval ...
• #### Dirichlet Approximation and Universal Dirichlet ﻿

[OWP-2016-12] (Mathematisches Forschungsinstitut Oberwolfach, 2016-08-16)
We characterize the uniform limits of Dirichlet polynomials on a right half plane. We extend the approximation theorems of Runge, Mergelyan and Vitushkin to the Dirichlet setting with respect to the Euclidean distance and ...
• #### 1406b - Dirichlet Series and Function Theory in Polydiscs ﻿

[OWR-2014-6] (2014) - (02 Feb - 08 Feb 2014)
The interaction between Dirichlet series and function theory in polydiscs dates back to a fundamental insight of Harald Bohr and the subsequent groundbreaking work on multilinear forms and polarization by Bohnenblust and ...
• #### 1413 - Flat Surfaces and Dynamics on Moduli Space ﻿

[OWR-2014-15] (2014) - (23 Mar - 29 Mar 2014)
Dynamics of the Teichmüller geodesic flow on the moduli space of curves and asymptotic monodromy of the Hodge bundle along this flow have numerous applications to dynamics and geometry of measured foliations, to billiards ...
• #### A Function Algebra Providing New Mergelyan Type Theorems in Several Complex Variables ﻿

[OWP-2019-02] (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-11)
For compact sets $K\subset \mathbb C^{d}$, we introduce a subalgebra $A_{D}(K)$ of $A(K)$, which allows us to obtain Mergelyan type theorems for products of planar compact sets as well as for graphs of functions.
• #### The Index of Singular Zeros of Harmonic Mappings of Anti-Analytic Degree One ﻿

[OWP-2017-03] (Mathematisches Forschungsinstitut Oberwolfach, 2017-02-02)
We study harmonic mappings of the form $f(z) = h(z) - \overline{z}$, where $h$ is an analytic function. In particular we are interested in the index (a generalized multiplicity) of the zeros of such functions. Outside the ...
• #### The Initial and Terminal Cluster Sets of an Analytic Curve ﻿

[OWP-2016-25] (Mathematisches Forschungsinstitut Oberwolfach, 2016-12-21)
For an analytic curve $\gamma : (a,b) \to \mathbb{C}$, the set of values approaches by $\gamma(t)$, as $t ↘a$ and as $t↗b$ can be any two continuua of $\mathbb{C} \cup \{\infty\}$.
• #### 1744a - Interplay between Number Theory and Analysis for Dirichlet Series ﻿

[OWR-2017-51] (2017) - (29 Oct - 04 Nov 2017)
In recent years a number of challenging research problems have crystallized in the analytic theory of Dirichlet series and its interaction with function theory in polydiscs. Their solutions appear to require unconventional ...
• #### 0807a - Mini-Workshop: Complex Approximation and Universality ﻿

[OWR-2008-6] (2008) - (10 Feb - 16 Feb 2008)
• #### 0950a - Mini-Workshop: The Escaping Set in Transcendental Dynamics ﻿

[OWR-2009-54] (2009) - (06 Dec - 12 Dec 2009)
The escaping set of a transcendental entire or meromorphic function consists of all points which tend to inﬁnity under iteration. Its importance in transcendental dynamics has increased signiﬁcantly in recent years. The ...
• #### A new counting function for the zeros of holomorphic curves ﻿

[OWP-2009-25] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-18)
Let $f_1,..., f_p$ be entire functions that do not all vanish at any point, so that $(f_1,..., f_p)$ is a holomorphic curve in $\mathbb{CP}^{p-1}$. We introduce a new and more careful notion of counting the order of the ...
• #### 1407 - New Trends in Teichmüller Theory and Mapping Class Groups ﻿

[OWR-2014-7] (2014) - (09 Feb - 15 Feb 2014)
The program “New Trends in Teichmüller Theory and Mapping Class Groups” brought together people working in various aspects of the field and beyond. The focus was on the recent developments that include higher Teichmüller ...
• #### Non-Extendability of Holomorphic Functions with Bounded or Continuously Extendable Derivatives ﻿
