Aside from being a reference for pursuit games, the book itself is a monumental work in : Authors : Nelson Dunford and Jacob T. Schwartz.

: The lion wants to eat the man; the man wants to survive.

In many mathematical circles, this book is cited as a reference in discussions about and pursuit-evasion problems. The "story" typically follows these lines:

: A famished lion and a man are trapped inside a closed circular arena.

: If both move at the same maximum speed, can the lion ever catch the man?

: It covers the general theory of linear operators, including spectral theory and the behavior of operators in Banach spaces.

: For years, it was believed the lion could always catch the man by staying on the same radius. However, in the 1950s, mathematician Abram Samoilovitch Besicovitch proved that the man can actually stay away from the lion forever by following a specific zigzag path, even in a confined space.
