# Cones and Duality

*Charalambos D. Aliprantis; Rabee Tourky*

Ordered vector spaces and cones made their debut in mathematics at the
beginning of the twentieth century. They were developed in parallel (but
from a different perspective) with functional analysis and operator theory.
Before the 1950s, ordered vector spaces appeared in the literature in a
fragmented way. Their systematic study began around the world after 1950
mainly through the efforts of the Russian, Japanese, German, and Dutch
schools.

Since cones are being employed to solve optimization problems, the theory of
ordered vector spaces is an indispensable tool for solving a variety of
applied problems appearing in several diverse areas, such as engineering,
econometrics, and the social sciences. For this reason this theory plays a
prominent role not only in functional analysis but also in a wide range of
applications.

This is a book about a modern perspective on cones and ordered vector
spaces. It includes material that has not been presented earlier in a
monograph or a textbook. With many exercises of varying degrees of
difficulty, the book is suitable for graduate courses.

Most of the new topics currently discussed in the book have their origins
in problems from economics and finance. Therefore, the book will be
valuable to any researcher and graduate student who works in mathematics,
engineering, economics, finance, and any other field that uses
optimization techniques.

#### Readership

Graduate students and research mathematicians interested in functional analysis and applications, in particular to optimization.

#### Reviews & Endorsements

...the book will be valuable not only for students and researchers in mathematics but also for those interested in economics, finance and engineering.

-- EMS Newsletter

As a whole, this book is an excellent reference of general interest in ordered vector spaces.

-- Mathematical Reviews

This book will find its grateful readership as it bridges the gap between the theory of ordered vector spaces as cultivated in functional analysis and the theory of positivity as requested in applications to economics.
