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

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

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

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

: 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.
