My main interests are mathematics and (real
played) games. For details please have a look to the second US edition of my book "**Luck, logic and white lies: The mathematics of games**", a translation of the 7th edition of my German book "Glück, Logik und Bluff". Publisher is Routledge (Taylor & Francis Group).

An overview can be found on the sheets of my talks "Games in the View of Mathematics (2017)" and "Games in the view of mathematics (2000)" at the University of Strathclyde, Glasgow on 23/11/2017 resp. on a symposium of AIMe (Association of Industrial Mathematics Eindhoven) on 3.11.2000.

During the preparation of my book I wrote also a little overview concerning "Go and Mathematics" (in German).

In the years 2017 to 2019 I published some papers concerning the topic of measuring skill in games, which are the base of the new forth part of the book.

Also you can find: Test your skill of bluffing in the simple betting-and-bluffing game QUAAK! (The computer is playing a mixed minimax strategy). And you can look at two animations of Monopoly: How to find the probabilities using a Monte Carlo simulation resp. a computation of the Markov chain. Finally there is a JavaScript based calculator for the odds in the game blackjack (description as pdf file) .

Another overview is dealing with the "Ideas of galois
theory" (in German) - of course
there isn't any relation to games. But there is a relation to my
second book "

**Galois theory
for beginners**: A historical perspective.
" (a translation of my German book "Algebra für Einsteiger: Von der
Gleichungsauflösung zur Galois-Theorie"). The book contains the classical formulas for
solving equations up to the fourth degree, methods to solve
cyclotomic equations and special equations of fifth degree. Last
but not least I give an introduction to Galois theory including a
lot of concrete examples. The translated book was published by the
AMS (American Mathematical Society).

**About my person:**

In 1985 I made my Ph.D. in Bonn. In my thesis, which was supervised by Günter Harder (later one of the directors of the "Max-Planck-Institut für Mathematik" in Bonn) , I used topological methods to prove a Lefschetz fixed point formula for twisted Hecke operators (on the level of the cohomology of arithmetic groups). In the case of rank one I characterised the boundary contributions of the Lefschetz number as a Lefschetz number of a truncated Hecke correspondence defined on the contracting parts of the boundary. As a conclusion I got arithmetic results like class number relations. In the general case the terms of the adelic version are based on orbital integrals. For newer and more general results look to Goresky/MacPherson, Arthur and Mahnkopf.

From 1998 until 2019 I was Managing Director of subsidiaries of the Gauselmann AG: First of Mega-Spielgeräte in Limburg, which
is designing AWPs (__a__musement __w__ith __p__rices,
that means "slot machines" to be operated in German
pubs and arcades; see also DMV-Mitteilungen 3/98) and internet terminals (Mega Web) and later of GeWeTe, which is producing
change machines and automated pay machines.
