Isaak Markovich Khalatnikov (Russian: Исаак Маркович Халатников; b. 17 October 1919) is a leading Ukrainian physicist, well known for his role in developing the BKL conjecture in general relativity. October 17 is the 290th day of the year (291st in leap years) in the Gregorian calendar. ... Year 1919 (MCMXIX) was a common year starting on Wednesday (link will display the full calendar). ... ... General relativity (GR) [also called the general theory of relativity (GTR) and general relativity theory (GRT)] is the geometrical theory of gravitation published by Albert Einstein in 1915/16. ...

Khalatnikov was born in Dnipropetrovsk and graduated from Dnipropetrovsk State University with a degree in Physics in 1941. He earned his doctorate in 1952. Location Map of Ukraine with Dnipropetrovsk highlighted. ...

Much of Khalatnikov's research has been a collaboration with, or inspired by, Lev Landau, including the Landau-Khalatnikov theory of superfluidity. Lev Davidovich Landau Lev Davidovich Landau (Russian language: Ле́в Дави́дович Ланда́у) (January 22, 1908 – April 1, 1968) was a prominent Soviet physicist, who made fundamental contributions to many areas of theoretical physics. ... Superfluidity is a phase of matter characterised by the complete absence of viscosity. ...

In 1970, inspired by the mixmaster model introduced by Charles W. Misner, then at Princeton University, Khalatnikov, together with Vladimir A. Belinsky and Evgeny Mikhailovich Lifshitz, introduced what has become known as the BKL conjecture, which is widely regarded as one of the most outstanding open problems in the classical theory of gravitation. Charles W. Misner is one of the authors of Gravitation. He has also invented Misner space, a topology and relativity-related mathematical structure. ...

Khalatnikov directed the Landau Institute for Theoretical Physics in Moscow from 1965 to 1992. He was elected to the Soviet Academy of Sciences in 1984. He has been awarded the Landau Prize and the Alexander von Humboldt Award, and is a foreign member of the Royal Society of London. L.D.
