Pattern formation in micromagnetics

Micromagnetics deals with the spatial pattern formed by the magnetization of a ferromagnet. From the point of view of mathematics, micromagnetics is an ideal testbed for a pattern-forming system in materials science: There are abundant experiments   more››

Structure Theorems in Graph Theory

Fix a graph H. What is the most general graph that does not contain H? In other words, how do we explicitly construct all the graphs that do not contain H? To begin to make this precise, we have to say what 'contain' means;; we have   more››
