Der Artikel Matroids: The Value of Abstraction versucht am Beispiel der Matroidtheorie den grossen Vorteil der Abstraktion in der Mathematik zu erlären.
A matroid is a mathematical construct, just as a group, a field, or a topology is a construct. It has a somewhat surprisingly large number of associated operators or special collections of subsets, and perhaps just as surprisingly, one can use any one of these to "define" what a matroid actually is. I'll be using the following definition, set forth by Oxley [...]
