This is a report on the workshop on Lattices and Applications in Number Theory held in Oberwolfach, from January 17 to January 23, 2016. The workshop brought together people working in various areas related to the field: ...
• #### 0009a - Lattices, Polytopes and Tilings ﻿

[TB-2000-9] (2000) - (27 Feb - 04 Mar 2000)
• #### Laws of small numbers : extremes and rare events ﻿

[OWS-23] (Birkhäuser Basel, 1994)
Since the publication of the first edition of this seminar book in 1994, the theory and applications of extremes and rare events have enjoyed an enormous and still increasing interest. The intention of the book is to give ...
• #### 0827b - Learning Theory and Approximation ﻿

[OWR-2008-30] (2008) - (29 Jun - 05 Jul 2008)
• #### 1226 - Learning Theory and Approximation ﻿

[OWR-2012-31] (2012) - (24 Jun - 30 Jun 2012)
Learning theory studies data structures from samples and aims at understanding unknown function relations behind them. This leads to interesting theoretical problems which can be often attacked with methods from Approximation ...
• #### 1627b - Learning Theory and Approximation ﻿

[OWR-2016-33] (2016) - (03 Jul - 09 Jul 2016)
The main goal of this workshop – the third one of this type at the MFO – has been to blend mathematical results from statistical learning theory and approximation theory to strengthen both disciplines and use synergistic ...
• #### Lectures on Algebraic Statistics ﻿

[OWS-39] (Birkhäuser Basel, 2009)
How does an algebraic geometer studying secant varieties further the understanding of hypothesis tests in statistics? Why would a statistician working on factor analysis raise open problems about determinantal varieties? ...
• #### Lectures on Hermitian-Einstein metrics for stable bundles and Kähler-Einstein metrics ﻿

[OWS-08] (Birkhäuser Basel, 1987)
These notes are based on the lectures I delivered at the German Mathematical Society Seminar in Schloss Michkeln in DUsseldorf in June. 1986 on Hermitian-Einstein metrics for stable bundles and Kahler-Einstein metrics. The ...
• #### Lectures on spaces of nonpositive curvature : with an appendix by Misha Brin Ergodicity of geodesic flows ﻿

[OWS-25] (Birkhäuser Basel, 1995)
Singular spaces with upper curvature bounds and, in particular, spaces of nonpositive curvature, have been of interest in many fields, including geometric (and combinatorial) group theory, topology, dynamical systems and ...
• #### Lectures on vanishing theorems ﻿

[OWS-20] (Birkhäuser Basel, 1992)
Introduction M. Kodaira's vanishing theorem, saying that the inverse of an ample invert­ ible sheaf on a projective complex manifold X has no cohomology below the dimension of X and its generalization, due to Y. Akizuki ...
• #### Legendrian Knots in Lens Spaces ﻿

[OWP-2011-01] (Mathematisches Forschungsinstitut Oberwolfach, 2011)
In this note, we first classify all topological torus knots lying on the Heegaard torus in Lens spaces, and then we classify Legendrian representatives of torus knots. We show that all Legendrian torus knots in universally ...
• #### Legendrian Lens Space Surgeries ﻿

[OWP-2016-10] (Mathematisches Forschungsinstitut Oberwolfach, 2016-06-17)
We show that every tight contact structure on any of the lens spaces $L(ns^2 - s + 1,s^2)$ with $n\geq 2, s \geq 1$, can be obtained by a single Legendrian surgery along a suitable Legendrian realisation of the negative ...
• #### Legendrian rational unknots in lens spaces ﻿

[OWP-2013-06] (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)
We classify Legendrian rational unknots with tight complements in the lens spaces $L(p,1)$ up to coarse equivalence. As an example of the general case, this classification is also worked out for $L(5, 2)$. The knots are ...
• #### Limits of graph sequences ﻿

[SNAP-2019-010-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-09-04)
Graphs are simple mathematical structures used to model a wide variety of real-life objects. With the rise of computers, the size of the graphs used for these models has grown enormously. The need to efficiently represent ...
• #### 0933 - Linear and Nonlinear Eigenproblems for PDEs ﻿

[OWR-2009-37] (2009) - (09 Aug - 15 Aug 2009)
The workshop discussed the numerical solution of linear and nonlinear eigenvalue problems for partial diﬀerential equations. It included the theoretical analysis the development of new (adaptive) methods, the iterative ...
• #### Linear Syzygies, Hyperbolic Coxeter Groups and Regularity ﻿

[OWP-2017-15] (Mathematisches Forschungsinstitut Oberwolfach, 2017-05-24)
We build a new bridge between geometric group theory and commutative algebra by showing that the virtual cohomological dimension of a Coxeter group is essentially the regularity of the Stanley–Reisner ring of its nerve. ...
• #### Linking and Closed Orbits ﻿

[OWP-2013-15] (Mathematisches Forschungsinstitut Oberwolfach, 2013-06-10)
We show that the Lagrangian of classical mechanics on a Riemannian manifold of bounded geometry carries a periodic solution of motion with prescribed energy, provided the potential satis es an asymptotic growth ...
• #### Local asymptotics for the area of random walk excursions ﻿

[OWP-2013-19] (Mathematisches Forschungsinstitut Oberwolfach, 2013-09-05)
We prove a local limit theorem for the area of the positive exursion of random walks with zero mean and finite variance. Our main result complements previous work of Caravenna and Chaumont, Sohier, as well as ...
• #### Localized Endomorphisms of Graph Algebras ﻿

[OWP-2011-04] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-7)
Endomorphisms of graph $C^*$-algebras are investigated. A combinatorial approach to analysis of permutative endomorphisms is developed. Then invertibility criteria for localized endomorphisms are given. Furthermore, ...
• #### Locally Compact Abelian p-Groups Revisited ﻿

[OWP-2017-06] (Mathematisches Forschungsinstitut Oberwolfach, 2017-03-03)
Even though the structure of locally compact abelian groups is generally considered to be rather thoroughly known through a wealth of publications, one keeps encountering corners that are not elucidated in up-to-date ...
