Klaus Truemper is Professor Emeritus of Computer Science. His research has focused on problems in Mathematics and Computer Science, but now also concerns questions of philosophy.

Is mathematics created or discovered? The answer has been debated for centuries. This book answers the question clearly and decisively by applying the concept of language games, invented by the philosopher Wittgenstein to solve difficult philosophical issues.

Matroid Decomposition (Revised Edition) , Leibniz Company, 2017. Can also be downloaded free of charge as e-book . See the Internet for mirror websites.

Matroids, first defined in 1935, are an abstract generalization of graphs and matrices. The book covers the part of the theory dealing with composition and decomposition of matroids. For the reader unfamiliar with matroid theory, the book may serve as an easy and intuitive introduction to that beautiful part of combinatorics.

Effective Logic Computation (Revised Edition) , Leibniz Company, 2017.

The book proposes an effective computational method for logic. It makes use of a theory of logic computation based on matroid theory, in particular matroid decomposition. The methodology is used in the Leibniz System.

Design of Logic-based Intelligent Systems , Wiley, 2004. Errata.

The book developes principles and methods for constructing intelligent systems for complex tasks that are readily done by humans but are difficult for machines.

German edition: Einführung in Wittgensteins Tractatus Logico-Philosophicus by F. Hülster, edited by K. Truemper, Leibniz Company, 2018.

In 1921, Ludwig Wittgenstein (1889-1951) published a landmark book in philosophy: the Tractatus Logico-Philosophicus, usually called just the Tractatus. It is an understatement to say that the Tractatus is difficult to read and understand. This book brings out the fundamental ideas of the Tractatus in simple, everyday language, with all concepts and conclusions illustrated by numerous examples taken from the natural sciences. This book is available in English as well as German.
