Large part of my research interests used to be centered around the concept of the monodromy matrix in its many forms and names:

  • The Fundamental Solution Matrix,
  • The Ordered Exponential Matrix,
  • The Floquet Matrix.

It is an integral matrix characterization of the periodic dynamical systems. John Baez gives nice layman explanation what it is. Related concepts are the Monodromy Group and the Monodromy Principle.

The Erdos Number

A simple metric on the space of the publishing mathematicians. That space consists of the discrete nodes that represent each publishing mathematician. For each jointly publication there is a link between the two nodes representing authors of that publication. If two authors have N common publications, the link connecting them has weight N. A distance between two nodes (x and y) is defined as the shortest number of steps from x to y. The Erdos Number is the distance (metric) of x to the one specific node (Paul Erdos). Majority of the nodes in the space belong to a one extremely large cluster/graph (a dominant/principal component). Still, there are many solitary nodes.

Mandorla is a medieval Italian term denoting the heart-like symbol consisting of two overlapping ovals/circles, where the almond-shaped area in the center gives name to the whole symbol (Mandorla stands for the Almond in Italian). It represents the overlapping (i.e. unity) of two otherwise separate domains, for example, of the left and right, of the dark and light, of the consciousness and the unconsciousness, human and god, The central area is the unity of heteregeneous natures, symbolising the transcedence of both.
