Informal introduction to the holonomy decomposition of transformation semigroups

The holonomy algorithm is the main method used in SgpDec for computational tools of the Krohn-Rhodes theory. The details of the algorithm might not be the easiest to grasp, but the underlying ideas are quite simple. Here is a short description of the general ideas used in the holonomy decomposition.

An algebraic view of computation

I am not particularly interested in doing philosophy, as my research is about using computers to extend mathematical knowledge. But it turns out that this involves questions that are not mathematical or technical, but of fundamental nature. I write code and run computer experiments all the time, so the question `What is computation?’ is on my mind continuously. Here is an attempt, a draft version of a somewhat philosophical paper to address the question for the $(n+1)$th time.

Euler's Formula in College Algebra

Once complex numbers are introduced in a College Algebra/PreCalculus course, why not discuss Euler’s formula? Especially the equation $e^{\pi i}+1=0$, that looks good on a T-shirt. A full proof is out of question, but the power series definitions of the exponential and trigonometric functions provide a walkable path up to the summit. With a computer algebra system it is easy to demonstrate how the approximations work, just by entering a few terms of the infinite sums.

Talk on finite computational structures

Here are the slides for my talk “Finite Computational Structures and Implementations” for the The 4th International Symposium on Computing and Networking CANDAR’16 held in Hiroshima, Japan, November 22-25, 2016.

The photo was taken in the Higashi Hiroshima Arts and Culture Hall, the venue of the conference.
