In his autobiography, Abraham Halevi Fraenkel describes growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. In his memoir, originally published in German in 1967, Fraenkel painted a unique picture of the complexity of Jewish life in Germany with special emphasis on the developments in the Orthodox community. He described the world of mathematics in Germany in the first half of the twentieth century, in the context of the great mathematicians he met, many of whom were Jews or had Jewish roots. In his personal life, Fraenkel merged the worlds of orthodox Judaism, liberal Zionism and mathematics, in a period of global and national upheavals, which included the two World Wars and the establishment of the State of Israel. The last chapter of the book, which describes his extensive public activity in Israel from the 1930s until his death in 1965, was written by Prof. Jiska Cohen-Mansfield. Introductions were added by Prof. Yehoshua Bar-Hillel and Prof. Menachem Magidor, the former president of the Hebrew University.

Graph Theory is, as far as we know, the first to be written by this approach. Its initial purpose was to serve as a high-school textbook for students learning graph theory in a systematic and orderly manner. Until the publication of this book, graph theory was only taught in academic institutions. The book soon began to serve as a reference book and even as a textbook in colleges and academic institutes for lecturers and students of mathematics and computer science. The book in its current format includes five chapters: 1. Definitions, Examples and Basic Concepts; 2. Paths and Circuits in Graphs; 3. Trees 4. Networks 5. Games, Puzzles and Graph Theory. The intention is to release it in a new and expanded edition.

This course book features a systematic method of presenting the foundations of modern algebra, focusing on three main theories: groups, rings, and fields. It contains numerous exercises.

Elementary School Mathematics is written for elementary school teachers as well as parents who wish to be involved in their childrens first steps in mathematical education. The reading of this book will benefit educators - whether at home or at school - by consolidating their content knowledge, while exposing them to both complexity and beauty of elementary mathematics.

Game theory is a mathematical discipline that deals with the modeling and the analysis of interactive decision situations. Such situations involve several decision makers that have different goals, and the decision of each one of them may affect the other decision makers. The theory originated in the 1940s, and since then it has been applied in many areas , like economics, biology, computer science, and political science. The book is especially well adapted to teaching: classical mathematical results are presented with mathematical completeness and rigor. The teacher will find all the material necessary for a mathematical understanding of the theory, without any need to use other sources. In addition, the book is replete with exercises of varying levels of difficulty, starting with easy exercises for beginners and ending with difficult ones suited for Ph.D. students.
