Analytic number theory

Number theory is such a vast and rich field that a one-year course cannot do justice to all its parts. The choice of topics included here is intended to provide some variety and some depth. Problems which have fascinated generations of professional and amateur mathematicians are discussed together with some of the techniques for solving them.

Knowledge iS POWER

This book cover a series of programming techniques used in sport programming competitions, such as ACM-ICPC, IOI, etc. It is incredible useful in practice because it contains the solution and the code of the problems.

Computational geometry emerged from the field of algorithms design and analysis in the late 1970s. It has grown into a recognized discipline with its own journals, conferences, and a large community of active researchers. The success of the field as a research discipline can on the one hand be explained from the beauty of the problems studied and the solutions obtained, and, on the other hand, by the many application domains—computer graphics, geographic information systems (GIS), robotics, and others—in which geometric algorithms play a fundamental role. For many geometric problems the early algorithmic solutions were either slow or difficult to understand and implement. In recent years a number of new algorithmic techniques have been developed that improved and simplified many of the previous approaches. In this textbook we have tried to make these modern algorithmic solutions accessible to a large audience. The book has been written as a textbook for a course in computational geometry, but it can also be used for self-study.

Diseño Mecánico

Sadly, just one year after the publication of the fourth German edition in 1997, my co-author Wolfgang Beitz died after a short but severe illness. His many outstanding contributions to engineering design, including his contribution to this book, were honoured in a memorialcolloquium held in Berlin. It would have made me very happy if he had been able to see the continuing success of our book, including its translation into Portuguese. Our collaboration was a perfect one— always fruitful, always beneficial. I am deeply grateful to him. The book, “Pahl/Beitz—Konstruktionslehre”, has now been translated into eight languages and recognized as an international reference text. For reasons of continuity, our publisher Springer wanted to pub- lish a fifth German edition of the book. To assist with this task two former students of Wolfgang Beitz became involved: Professor Dr.-Ing. Jörg Feldhusen and Professor Dr.-Ing. Karl-Heinrich Grote, both of whom have continually promoted and expanded his ideas. Professor Feldhusen worked for many years as a senior designer in the auto- motive industry and is now at RWTH Aachen University, succeeding Professor Dr. Ing. R. Koller. Professor Grote has considerable experience of teaching design and running projects as a Professor in the USA, and is now at the Otto-von-Guericke University in Magdeburg. He succeeded Professor Beitz as the Editor of the Dubbel Handbook for Mechanical Engineering.
