Raphael Høegh-Krohn

Jan Raphael Høegh-Krohn (10 February 1938 – 24 January 1988) was a Norwegian mathematician.

He finished his Ph.D. in 1966, titled ''On Partly Gentle Perturbation with Application to Perturbation by Annihilation-Creation Operator,'' under the supervision of Kurt Friedrichs at the New York University.

He authored over 150 papers and is known for the discovery of a fundamental duality in relativistic quantum statistical mechanics by representing the basic correlation functions in terms of a certain stochastic process, now known as the Høegh-Krohn process. Provided by Wikipedia
