Rouben V. Ambartzumian () (born 1941) is an Armenian mathematician and Academician of National (Academy of Sciences of Republic of Armenia ) . He worked 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. Kendalll 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.〔R. V. Ambartzumian, A note on pseudo-metrics on the plane, Zeitschrift für Wahrscheinlichkeitstheorie und Verwandte Gebiete 1976, Volume 37, Issue 2, pp 145-155〕 He is a holder of the Rollo Davidson Prize of Cambridge University of 1982.〔(【引用サイトリンク】title=Prize Winners 1976-2014 )〕 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".〔Computed Tomography, Some History and Recent Developments, Proc. of Symposia in Applied Mathematics, Vol. 29, p. 35, 1985〕 Victor Hambardzumyan, in his book "A Life in Astrophysics",〔V. A. Ambartsumian, A Life in Astrophysics : Selected Papers of Viktor Ambartsumian, New York: Allerton Press, 1998, ISBN 0-89864-082-2〕 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.〔http://ambartsumian.ru/en/papers/epilogue-ambartsumian’-s-paper/〕 ==Experience==
