◀▲▶History / 20th-century / Person: Sharkovsky, Oleksandr Mikolaiovich

Oleksandr Sharkovsky was a Ukrainian mathematician who made contributions to the theory of discrete dynamical systems.

Mathematical Profile (Excerpt):

• Sharkovsky's main areas of interest are the theory of dynamical systems, the theory of stability and the theory of oscillations.
• He published this result, known today as Sharkovsky's Theorem, in the Russian paper Co-existence of cycles of a continuous mapping of the line into itself (1964).
• Although the result did not attract a great deal of interest at the time of its publication, during the 1970s other surprising results were proved which turned out to be special cases of Sharkovsky's theorem.
• The Sharkovsky theorem led to the appearance of numerous works in this direction, where one can often encounter terms such as the Sharkovsky theorem, Sharkovsky order, Sharkovsky space, Sharkovsky
