• #### Fokus-Erkennung bei Epilepsiepatienten mithilfe moderner Verfahren der Zeitreihenanalyse ﻿

[SNAP-2016-008-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2016)
Viele epileptische Anfälle entstehen in einer begrenzten Region im Gehirn, dem sogenannten Anfallsursprung. Eine chirurgische Entfernung dieser Region kann in vielen Fällen zu Anfallsfreiheit führen. Aus diesem Grund ist ...

• #### Formal adjoints of linear DAE operators and their role in optimal control ﻿

[OWP-2011-15] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-16)
For regular strangeness-free linear differential-algebraic equations (DAEs) the definition of an adjoint DAE is straightforward. This definition can be formally extended to general linear DAEs. In this paper, we analyze ...
• #### Formal punctured ribbons and two-dimensional local fields ﻿

[OWP-2008-01] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-05)
We investigate formal ribbons on curves. Roughly speaking, formal ribbon is a family of locally linearly compact vector spaces on a curve. We establish a one-to-one correspondence between formal ribbons on curves plus some ...
• #### Formation Control and Rigidity Theory ﻿

[SNAP-2019-017-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-12-11)
Formation control is one of the fundamental coordination tasks for teams of autonomous vehicles. Autonomous formations are used in applications ranging from search-and-rescue operations to deep space exploration, with ...
• #### 1922 - Foundations and New Horizons for Causal Inference ﻿

[OWR-2019-25] (2019) - (26 May - 01 Jun 2019)
While causal inference is established in some disciplines such as econometrics and biostatistics, it is only starting to emerge as a valuable tool in areas such as machine learning and artificial intelligence. The ...
• #### 2118 - Foundations of Bayesian Inference for Complex Statistical Models (hybrid meeting) ﻿

[OWR-2021-22] (2021) - (02 May - 08 May 2021)
In this virtual workshop a variety of recent developments in Bayesian high-dimensional and nonparametric statistics were discussed in depth. There were 12 in depth talks delivered via zoom in the afternoons (to allow for ...
• #### 0632 - Four-dimensional Manifolds ﻿

[OWR-2006-35] (2006) - (06 Aug - 12 Aug 2006)
This workshop has provided a broad panorama of recent developments in the study of topological, smooth, and symplectic 4-manifolds. Related invariants of knots and 3-manifolds were also discussed.
• #### The Fourier Transform on Harmonic Manifolds of Purely Exponential Volume Growth ﻿

[OWP-2019-12] (Mathematisches Forschungsinstitut Oberwolfach, 2019-05-08)
Let $X$ be a complete, simply connected harmonic manifold of purely exponential volume growth. This class contains all non-flat harmonic manifolds of non-positive curvature and, in particular all known examples of harmonic ...
• #### Fourier-Mukai transform on Weierstrass cubics and commuting differential operators ﻿

[OWP-2016-03] (Mathematisches Forschungsinstitut Oberwolfach, 2016-05-10)
In this article, we describe the spectral sheaves of algebras of commuting differential operators of genus one and rank two with singular spectral curve, solving a problem posed by Previato and Wilson. We also classify all ...
• #### 1524 - Free Probability Theory ﻿

[OWR-2015-28] (2015) - (07 Jun - 13 Jun 2015)

• #### 0513 - Free Probability Theory ﻿

[OWR-2005-15] (2005) - (27 Mar - 02 Apr 2005)
Free probability theory is a line of research which parallels aspects of classical probability, in a non-commutative context where tensor products are replaced by free products, and independent random variables are replaced ...
• #### Freeness of Multi-Reflection Arrangements via Primitive Vector Fields ﻿

[OWP-2017-10] (Mathematisches Forschungsinstitut Oberwolfach, 2017-04-20)
In 2002, Terao showed that every reflection multi-arrangement of a real reflection group with constant multiplicity is free by providing a basis of the module of derivations. We first generalize Terao's result to ...
• #### Friezes and tilings ﻿

[SNAP-2015-004-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
Friezes have occured as architectural ornaments for many centuries. In this snapshot, we consider the mathematical analogue of friezes as introduced in the 1970s by Conway and Coxeter. Recently, infinite versions of such ...
• #### 1310 - From "Mixed" to "Applied" Mathematics: Tracing an important dimension of mathematics and its history ﻿

[OWR-2013-12] (2013) - (03 Mar - 09 Mar 2013)
