Closed geodesics on surfaces and Riemannian manifolds
[SNAP-2017-005-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-07)
Geodesics are special paths in surfaces and so-called
Riemannian manifolds which connect close points
in the shortest way. Closed geodesics are geodesics
which go back to where they started. In this snapshot
we talk ...
Spaces of Riemannian metrics
[SNAP-2017-010-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-28)
Riemannian metrics endow smooth manifolds such as
surfaces with intrinsic geometric properties, for example
with curvature. They also allow us to measure
quantities like distances, angles and volumes. These
are the ...
Drogen, Herbizide und numerische Simulation
[SNAP-2014-010-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2017-08)
Die kolumbianische Regierung versprüht Unkrautbekämpfungsmittel (Herbizide) über Coca-Feldern, um die Drogenproduktion im Land zu reduzieren. Sprühverwehungen entlang der Grenze Kolumbiens zu Ecuador wurden zu einem ...
