Reflections on hyperbolic space
[SNAP-2021-007-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2021-08-24)In school, we learn that the interior angles of any triangle sum up to pi. However, there exist spaces different from the usual Euclidean space in which this is not true. One of these spaces is the ''hyperbolic space'', ... -
Searching for structure in complex data: a modern statistical quest
[SNAP-2021-003-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2021-03-29)Current research in statistics has taken interesting new directions, as data collected from scientific studies has become increasingly complex. At first glance, the number of experiments conducted by a scientist must ... -
Ultrafilter methods in combinatorics
[SNAP-2021-006-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2021-06-25)Given a set X, ultrafilters determine which subsets of X should be considered as large. We illustrate the use of ultrafilter methods in combinatorics by discussing two cornerstone results in Ramsey theory, namely ... -
Zopfgruppen, die Yang–Baxter-Gleichung und Unterfaktoren
[SNAP-2021-005-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2021-06-24)Die Yang–Baxter-Gleichung ist eine faszinierende Gleichung, die in vielen Gebieten der Physik und der Mathematik auftritt und die am besten diagrammatisch dargestellt wird. Dieser Snapshot schlägt einen weiten Bogen ...
