I am attending a short workshop from 30th April to 4th May on the topic of Nonlinear Time Series Analysis organized by the Indian Institute of Sciences, Bangalore. The course is being taught by Professor Marco Bittelli of the University of Bologna. I intend to keep (very brief) summaries of what is covered each day as it…

Starting off: The notion of a group

In this series of posts exploring the Rubik’s Cube, the notion of a group is going to be central. A set and an operation @ (like +, *, – ) are said to form a group if they satisfy the following conditions. (The text above looks different because I had to first type it in Tex and then take…
