- Ruben W. Ambarzumjan (russisch Рубен Викторович Амбарцумя, englisch Rouben V. Ambartzumian, armenisch Ռուբեն Համբարձումյան Ruben Hambardsumjan; * 28. Oktober 1941 in Jelabuga) ist ein sowjetisch-armenischer Mathematiker. (de)
- Rouben V. Ambartzumian (Armenian: Ռուբեն Վ․ Համբարձումյան;Russian: Рубен В. Амбарцумян) (born 1941) is an Armenian mathematician and Academician of National Academy of Sciences of Armenia. He works in Stochastic Geometry and Integral Geometry where he created a new branch, combinatorial integral geometry. The subject of combinatorial integral geometry received support from mathematicians K. Krickeberg and D. G. Kendall at the 1976 Sevan Symposium (Armenia) which was sponsored by Royal Society of London and The London Mathematical Society. In the framework of the later theory he solved a number of classical problems in particular the solution to the Buffon Sylvester problem as well as the Hilbert's fourth problem in 1976. He is a holder of the Rollo Davidson Prize of Cambridge University of 1982. Rouben's interest in Integral Geometry was inherited from his father. Nobel prize winner Allan McLeod Cormack Laureate for Tomography wrote: "Ambartsumian gave the first numerical inversion of the Radon transform and it gives the lie to the often made statement that computed tomography would have been impossible without computers". Victor Hambardzumyan, in his book "A Life in Astrophysics", wrote about the work of Rouben V. Ambartzumian, "More recently, it came to my knowledge that the invariance principle or invariant embedding was applied in a purely mathematical field of integral geometry where it gave birth to a novel, combinatorial branch." See R. V. Ambartzumian, «Combinatorial Integral Geometry», John Wiley, 1982. (en)

Filho do astrofísico Viktor Ambartsumian, cresceu em Erevan, onde viveu a maior parte do tempo. Estudou matemática a partir de 1959 na Universidade Estatal de Moscou, obtendo o diploma em 1962, com doutorado no Instituto de Matemática Steklov, orientado por Yuri Prokhorov, onde obteve a habilitação em 1975 (Doktor nauk). A partir de 1968 foi diretor do Instituto de Matemática da . Em 1992 foi durante meio ano pesquisador visitante na Universidade Temple. Foi palestrante convidado do Congresso Internacional de Matemáticos em Vancouver (1974 - Solution of the Buffon-Sylvester problem and stereology). Recebeu o Prêmio Rollo Davidson de 1982. (pt)
