E-Book Overview
This book presents the basics of mathematics that are needed for learning the physics of today. It describes briefly the theories of groups and operators, finite- and infinite-dimensional algebras, concepts of symmetry and supersymmetry, and then delineates their relations to theories of relativity and black holes, classical and quantum physics, electroweak fields and Yang–Mills. It concludes with a chapter on (the complex theory of) strings and superstrings and their link to black holes — an idea that fascinates both the physicist and the mathematician.

To reach this goal, however, the theory that is pursued at research level in selected schools has to be made available to a wider audience. This is possible only if the teaching (and a text) focuses not only on the string and superstring theories but also provides: (i) the elements of all the prerequisites; (ii) an overview of other great theories that have preceded it (since it uses their phenomenology); and (iii) a motivational thread to reach the end goal. The present text is organized to fulfill these objectives. Since the target here is a much larger population of physicists and mathematicians, we avoid the mathematical rigor. No theorems (with few exceptions) are proved in the main text, in fact they are stated as 'Results' and 'Facts,' and their proofs (in important cases) are given as solutions to the exercises at the end of a section. This offers the reader (the teacher) the option of choosing the preferred level of in-depth/non-depth coverage (in a class). Besides this, the material is often presented using the two points of view (mathematics and physics) which makes the subject easily comprehensible. The first six chapters provide
