Partial Differential Equations in Physics

The topic with which I regularly conclude my six-term series of lectures in Munich is the partial differential equations of physics. We do not really deal with mathematical physics, but with physical mathematics; not with the mathematical formulation of physical facts, but with the physical motivation of mathematical methods. The oftmentioned “prestabilized harmony” between what is mathematically interesting and what is physically important is met at each step and lends an esthetic - I should like to say metaphysical -- attraction to our subject. The problems to be treated belong mainly to the classical matherhatical literature, as shown by their connection with the names of Laplace, Fourier, Green, Gauss, Riemann, and William Thomson. In order to show that these methods are adequate to deal with actual problems, we treat the propagation of radio waves in some detail in Chapter VI.

Symplectic Geometry

  • 1st Edition

Symplectic Geometry focuses on the processes, methodologies, and numerical approaches involved in symplectic geometry. The book first offers information on the symplectic and discontinuous groups, symplectic metric, and hermitian forms. Numerical calculations are presented to show the values and transformations of these groups. The text then examines the fundamental domain of the modular group and the volume of the fundamental domain of the modular group. Equations and matrices are provided to show the fundamental domain and volume of the fundamental domain of the modular group. The publication ponders on commensurable groups and unit groups of quinary quadratic forms. Numerical analyses are also offered to show the values and characteristics of commensurable and unit groups. The text is a helpful reference for researchers interested in symplectic geometry.

Planning IT

Planning IT provides a framework for assessing and improving the practice of information management in organizations. It describes the ways in which senior managers can diagnose the situation in their enterprise and generate an appropriate action plan. The book thus helps the manage, to make a more proactive and informed response to the opportunities of modern information technology and information systems. Comprised of nine chapters, this book begins with an introduction to six guidelines for information management: establish an information management partnership; distinguish the potential benefits of information technology and information systems; think strategically about information management; identify the benefits and their value; manage the achievement of the benefits; and prepare for the future. The next six chapters address each of these guidelines in more detail, and each chapter ends with a set of questions which the manager should consider in the context of himself/herself and his/her enterprise. This will produce a score, and some action points, as part of an information management audit. The eighth chapter explains how to produce a consolidated action plan, structured according to the time scale of the individual actions (short- or long-term) and according to whether they are personal or team actions in the enterprise. The last chapter consolidates the book's main points and exhorts the manager to action. This monograph is intended for both senior managers and non-specialists in information technology.

This volume contains 31 papers prepared for the Colloquium on Mathematical Logic in Programming held in Salgótarján, Hungary. Main topics of the Colloquium include:- Model theoretical, universal algebra and category theoretical approaches to program semantics- Logical and model theoretical approaches to program-verification, data representation and problem specification- Logical and model theoretical approaches to theorem proving, automatic programming and automatic problem solving- Very high level, logical based programming languages.

Among the large number of international combinatorial colloquia organized in Hungary by the János Bolyai Mathematical Society, this was the first one devoted entirely to matroid theory. Tutorial series on regular matroids and matroid minors, oriented matroids, matroid oracles, engineering applications of matroids, and a large number of invited and contributed talks gave an up-to-date picture of this rapidly developing branch of discrete mathematics. Special attention was paid to the applications of matroids, which are becoming more and more important in many areas.
