0911  Enveloping Algebras and Geometric Representation Theory
[OWR200915] (2009)  (08 Mar  14 Mar 2009)The meeting brought together experts investigating Lie theory from the geometric, algebraic and combinatorial points of view to discuss recent progress and bring forward the research in this area by fostering scientiﬁc ... 
1210  Enveloping Algebras and Geometric Representation Theory
[OWR201213] (2012)  (04 Mar  10 Mar 2012)The workshop brought together experts investigating algebraic Lie theory from the geometric and combinatorial points of view. 
Epsilonhypercyclic operators
[OWP200819] (Mathematisches Forschungsinstitut Oberwolfach, 20080319)For each fixed number $\varepsilon$ in $(0, 1)$ we construct a bounded linear operator on the Banach space $\ell_1$ having a certain orbit which intersects every cone of aperture $\varepsilon$, but with every orbit avoiding ... 
Equidistribution of Elements of Norm 1 in Cyclic Extensions
[OWP201414] (Mathematisches Forschungsinstitut Oberwolfach, 20140820)Upon quotienting by units, the elements of norm 1 in a number field $K$ form a countable subset of a torus of dimension $r_1+r_21$ where $r_1$ are the numbers of real and pairs of complex embeddings. When $K$ is Galois ... 
Estimating the volume of a convex body
[SNAP2018015EN] (Mathematisches Forschungsinstitut Oberwolfach, 20181230)Sometimes the volume of a convex body needs to be estimated, if we cannot calculate it analytically. We explain how statistics can be used not only to approximate the volume of the convex body, but also its shape. 
Euler Reflexion Formulas for Motivic Multiple Zeta Functions
[OWP201517] (Mathematisches Forschungsinstitut Oberwolfach, 20151118)We introduce a new notion of *product of two integrable series with coeficients in distinct Grothendieck rings of algebraic varieties, preserving the integrability and commuting with the limit of rational series. In the ... 
Evenhomogeneous supermanifolds on the complex projective line
[OWP201302] (Mathematisches Forschungsinstitut Oberwolfach, 20130314)The classification of evenhomogeneous complex supermanifolds of dimension $1m$, $m<=3$, on $\mathbb{CP}^1$ up to isomorphism is given. An explicit description of such supermanifolds in terms of local charts and coordinates ... 
Exact Rate of Convergence of kNearestNeighbor Classification Rule
[OWP201725] (Mathematisches Forschungsinstitut Oberwolfach, 20171016)A binary classification problem is considered. The excess error probability of the knearest neighbor classification rule according to the error probability of the Bayes decision is revisited by a decomposition of the ... 
Exceptional Legendrian Torus Knots
[OWP201804] (Mathematisches Forschungsinstitut Oberwolfach, 20180321)We present classification results for exceptional Legendrian realisations of torus knots. These are the first results of that kind for nontrivial topological knot types. Enumeration results of DingLiZhang concerning ... 
Expander graphs and where to find them
[SNAP2019016EN] (Mathematisches Forschungsinstitut Oberwolfach, 20191122)Graphs are mathematical objects composed of a collection of “dots” called vertices, some of which are joined by lines called edges. Graphs are ideal for visually representing relations between things, and mathematical ... 
Experimenting with Symplectic Hypergeometric Monodromy Groups
[OWP201915] (Mathematisches Forschungsinstitut Oberwolfach, 20190522)We present new computational results for symplectic monodromy groups of hypergeometric differential equations. In particular, we compute the arithmetic closure of each group, sometimes justifying arithmeticity. The results ... 
Experimenting with Zariski Dense Subgroups
[OWP201731] (Mathematisches Forschungsinstitut Oberwolfach, 20171028)We give a method to describe all congruence images of a finitely generated Zariski dense group $H\leq SL(n, \mathbb{R})$. The method is applied to obtain efficient algorithms for solving this problem in odd prime degree ... 
An Explicit Formula for the Dirac Multiplicities on Lens Spaces
[OWP201419] (Mathematisches Forschungsinstitut Oberwolfach, 2014)We present a new description of the spectrum of the (spin) Dirac operator $D$ on lens spaces. Viewing a spin lens space $L$ as a locally symmetric space $\Gamma \setminus Spin(2m)/Spin(2m1)$ and exploiting the representation ...
