A textbook for a first-year PhD course in mathematics for economists and a reference for graduate students in economics.

The book contains the round table reports of the first European Congress of Mathematics, a new feature of this Congress devoted to furthering the contribution of mathematics to society and reporting on its interaction with the exact and social sciences. Topics: • Mathematics and the general public • Women and mathematics • Mathematics and educational policy • Let's cultivate mathematics! • Mathematical Europe: Myth or historical reality? • Philosophie des mathématiques : pourquoi ? comment ? • Mathématiques et sciences sociales • Mathe- matics and industry • Degree harmonization and student exchange programmes • The Pythagoras programme • Collaboration with devel- oping countries • Mathematical libraries in Europe • Mathematics and economics • Mathématiques et Chimie • Mathematics in medicine and biology. This book is also available in hardcover as Volume 121 of the series Progress in Mathematics, where it forms part of the three-volume set First European Congress of Mathematics. Volumes I (Invited Lectures Part 1) and II (Invited Lectures Part 2) of this set are also available separately as Volumes 119 and 120, respectively, of Progress in Mathematics.

These volumes chart the fundamental - methodological and analytical - change in economics that arose in the second half of the nineteenth century. The main characteristics of this change included an increasing reliance on mathematical methods, a revolution in the theory of value, and the rise of general equilibrium theory. This collection traces this long revolution over a fifty-year period for the first time, from William Stanley Jevons' The Theory of Political Economy (1871), to Eugen Slutsky's On the Theory of the Budget of the Consumer (1915).

​​​​In this book the authors take a rigorous look at the infinite-horizon discrete-time optimal control theory from the viewpoint of Pontryagin’s principles. Several Pontryagin principles are described which govern systems and various criteria which define the notions of optimality, along with a detailed analysis of how each Pontryagin principle relate to each other. The Pontryagin principle is examined in a stochastic setting and results are given which generalize Pontryagin’s principles to multi-criteria problems. ​Infinite-Horizon Optimal Control in the Discrete-Time Framework is aimed toward researchers and PhD students in various scientific fields such as mathematics, applied mathematics, economics, management, sustainable development (such as, of fisheries and of forests), and Bio-medical sciences who are drawn to infinite-horizon discrete-time optimal control problems.
