Molecular Quantum Dynamics
[SNAP-2017-006-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-10-24)
We provide a brief introduction to some basic ideas
of Molecular Quantum Dynamics. We discuss the
scope, strengths and main applications of this field
of science. Finally, we also mention open problems
of current ...
Mathematische Modellierung von Krebswachstum
[SNAP-2017-004-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2017-10-17)
Krebs ist eine der größten Herausforderungen der modernen
Medizin. Der WHO zufolge starben 2012 weltweit
8,2 Millionen Menschen an Krebs. Bis heute sind
dessen molekulare Mechanismen nur in Teilen verstanden,
was eine ...
Aperiodic Order and Spectral Properties
[SNAP-2017-003-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-09-14)
Periodic structures like a typical tiled kitchen floor
or the arrangement of carbon atoms in a diamond
crystal certainly possess a high degree of order. But
what is order without periodicity? In this snapshot,
we are ...
A few shades of interpolation
[SNAP-2017-007-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-07)
The topic of this snapshot is interpolation. In the
ordinary sense, interpolation means to insert something
of a different nature into something else. In
mathematics, interpolation means constructing new
data points ...
Computational Optimal Transport
[SNAP-2017-008-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-21)
Optimal transport is the mathematical discipline of
matching supply to demand while minimizing shipping
costs. This matching problem becomes extremely
challenging as the quantity of supply and demand
points increases; ...
Mathematics plays a key role in scientific computing
[SNAP-2017-011-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-29)
I attended a very interesting workshop at the research
center MFO in Oberwolfach on “Recent Developments
in the Numerics of Nonlinear Hyperbolic Conservation
Laws”. The title sounds a bit technical,
but in plain language ...
Solving quadratic equations in many variables
[SNAP-2017-012-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-30)
Fields are number systems in which every linear equation
has a solution, such as the set of all rational
numbers $\mathbb{Q}$ or the set of all real numbers $\mathbb{R}$. All fields
have the same properties in relation ...
Computing the long term evolution of the solar system with geometric numerical integrators
[SNAP-2017-009-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-27)
Simulating the dynamics of the Sun–Earth–Moon system
with a standard algorithm yields a dramatically
wrong solution, predicting that the Moon is ejected
from its orbit. In contrast, a well chosen algorithm
with the ...
News on quadratic polynomials
[SNAP-2017-002-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-07-18)
Many problems in mathematics have remained unsolved because of missing links between mathematical disciplines, such as algebra, geometry, analysis, or number theory. Here we introduce a recently discovered result concerning ...
Winkeltreue zahlt sich aus
[SNAP-2017-001-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2017-08-23)
Nicht nur Seefahrerinnen, auch Computergrafikerinnen
und Physikerinnen wissen Winkeltreue zu schätzen.
Doch beschränkte Rechenkapazitäten und Vereinfachungen
in theoretischen Modellen erfordern es,
winkeltreue Abbildungen ...
