On radial basis functions
[SNAP-2019-002-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-03-13)
Many sciences and other areas of research and applications from engineering to economics require the approximation of functions that depend on many variables. This can be for a variety of reasons. Sometimes we have a ...
Snake graphs, perfect matchings and continued fractions
[SNAP-2019-001-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-13)
A continued fraction is a way of representing a real number by a sequence of integers. We present a new way to think about these continued fractions using snake graphs, which are sequences of squares in the plane. You ...
Positive Scalar Curvature and Applications
[SNAP-2019-004-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-04-25)
We introduce the idea of curvature, including how it developed historically, and focus on the scalar curvature of a manifold. A major current research topic involves understanding positive scalar curvature. We discuss ...
Algebra, matrices, and computers
[SNAP-2019-005-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-05-03)
What part does algebra play in representing the real world abstractly? How can algebra be used to solve hard mathematical problems with the aid of modern computing technology? We provide answers to these questions that ...
Diophantine equations and why they are hard
[SNAP-2019-003-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-04-24)
Diophantine equations are polynomial equations whose solutions are required to be integer numbers. They have captured the attention of mathematicians during millennia and are at the center of much of contemporary research. ...
