David Gale – författare

In the past few decades, methods of linear algebra have become central to economic analysis, replacing older tools such as the calculus. David Gale has provided the first complete and lucid treatment of important topics in mathematical economics which can be analyzed by linear models. This self-contained work requires few mathematical prerequisites and provides all necessary groundwork in the first few chapters. After introducing basic geometric concepts of vectors and vector spaces, Gale proceeds to give the main theorems on linear inequalities—theorems underpinning the theory of games, linear programming, and the Neumann model of growth. He then explores such subjects as linear programming; the theory of two-person games; static and dynamic theories of linear exchange models, including problems of equilibrium prices and dynamic stability; and methods of play, optimal strategies, and solutions of matrix games. This book should prove an invaluable reference source and text for mathematicians, engineers, economists, and those in many related areas.

For those fascinated by the abstract universe of mathematics, David Gale''s columns in The Mathematical Intelligencer have been a prime source of entertainment. Here Gale''s columns are collected for the first time in book form. Encouraged by the magazine''s editor, Sheldon Axler, to write on whatever pleased him, Gale ranged far and wide across the field of mathematics but frequently returned to favorite themes: triangles, tilings, the mysterious properties of sequences given by simple recursions, games and paradoxes, and the particular automaton that gives this collection its title, the "automatic ant". The level is suitable for those with some familiarity with mathematical ideas, but great sophistication is not needed.
