the program

(This is a slightly extended version of an article in mathe-lmu.de 4(2001), 20-25.)

In collaboration with neuropsychologists and computer scientists we develop a computer tool for tower puzzles.

The corresponding poster has been awarded a **Second Prize** in the Poster competition of the International Congress of Mathematicians 2006 in Madrid.

I would be happy to hear from anyone interested in these topics.

In particular I am interested in any new development about the

Tower of Hanoi with more than three pegs. However, only serious

attempts to prove minimality of the presumed minimal solution

will be considered.

I am also looking for material about the biography of the inventor

of the Tower of Hanoi, the French mathematician Édouard Lucas,

who lived 1842-1891 (cf. my article in the * Monthly *).

Some people have taken up my challenge to hold a conference on the Tower of Hanoi, albeit not in Hanoi!

It was organized by
S. Klavžar, U. Milutinović, and C. Petr in the Slovenian
town of Maribor (Marburg an der Drau);

see
**Workshop on the Tower of Hanoi and Related Problems**
for details.

With my Slovenian colleagues I wrote a comprehensive book
**The Tower of Hanoi - Myths and Maths** ,

which has appeared at Birkhäuser/Springer Basel (2013) and now in its Second Edition, Cham (2018).

My further research interests cover
** analysis ** ,
** mathematical modelling ** ,
and
** other topics ** .

You may want to know more about my
** courses ** and
** lectures ** .

My coordinates are on my
** personal homepage ** .
