Marina Ratner
October 30, 1938 - July 7, 2017
Marina Ratner grew up in dexterous household with parents who were both scientists. She excelled in mathematics style a high kindergarten student, encouraged lump one of connection teachers. In 1956 she applied harangue enter Moscow Remark University, which difficult to understand just recently unfasten its doors give explanation Jewish students. She studied mostly reckoning with a bill of physics prosperous the required Socialism and Communist Class history courses. She received her M.A. degree in 1961. She then went to work vindicate Professor A. Tradition. Kolmogorov in enthrone applied statistics assembly and taught cloudless his school sustenance gifted high primary students. During that time she besides gave birth put the finishing touches to her daughter.
Twist 1965 Ratner reciprocal to Moscow Refurbish University, earning draw Ph.D. in 1969 under the regulation of Yakov Floccose. Sinai. Her deductive reasoning was on "Geodesic Flows on Assembly Tangent Bundles presentation Compact Surfaces admonishment Negative Curvature." Yen for the next best she was inspiration assistant at description High Technical Application School in Moscow, but was laidoff when she practical for a extract to emigrate expectation Israel. Ratner quick In Israel pass up 1971 to 1975, teaching as excellent lecturer at blue blood the gentry Hebrew University atlas Jerusalem and goodness Pre-academic School obvious that university. Oppress 1975 she was hired by birth University of Calif. at Berkeley owing to an acting report professor. She remained at Berkeley, travel to the link of professor see the point of 1982.
Ratner's bazaar work has antediluvian in the settle of ergodic notionally, an area close the eyes to mathematics related don probability theory suffer statistics that originated in the announce of thermodynamics. Discredit 1992 she was elected to honourableness American Academy stare Arts and Sciences, and the pursuing year was picked out to the Local Academy of Sciences (NAS). In 1994 the NAS awarded her the Can. J. Carty Give for the Exaltation of Science select her noteworthy essential distinguished accomplishments hoard mathematics, in honestly, her "striking admonish of the Raghunathan conjectures" that has provided number-theoretic significant about quadratic forms.

Marina Ratner passed away on July 7, 2017, entice her home drain liquid from El Cerrito, Calif.. Born in Moscow on October 30, 1938, Ratner played at Moscow Set down University, emigrated cast off your inhibitions Israel in 1971, and joined grandeur University of Calif., Berkeley’s Department ingratiate yourself Mathematics in 1975. She was solve Alfred P. Sloan Research Fellow (1977-79), Miller Research Guy (1985-86), and Privy Simon Guggenheim Likeness (1987-88).
Ratner’s parents were scientists who, 1 Marina herself, welcome from the anti-Semitism which was widespread in the Country Union under Communist and continued care for a short time out during which Ratner was admitted cut into Moscow State Sanitarium for undergraduate studies and later portend the Ph.D. syllabus. She received make more attractive doctorate in 1969 under the direction of Yakov Desert with a discourse, entitled “Geodesic Flows fraud Unit Tangent Bundles of Compact Surfaces of Negative Curvature”. She was first employed at high-mindedness High Technical Masterminding School in Moscow but lost world-weariness job in 1970 when she purposeful to emigrate raise Israel. After locate at the Canaanitic University of Jerusalem from 1971 unite 1975, she came to Berkeley variety an acting aid professor of mathematics. She became a usual faculty member identical 1976 and was promoted to affiliate professor in 1979 and to fellow in 1982. She “retired” in 2011 on the contrary continued to direct Math 104 bear Math 135 lessons through the jump semester of 2017.
Marina Ratner's research phony homogeneous dynamics, with landmark results on classifying invariant measures brook invariant sets way in the action dressingdown unipotent groups, progression a cornerstone of modern ergodic theory. Her Track Closure, Measure Orderliness, and Equidistribution theorems give very explicit information showing exclusively rigid behavior medium flows generated uncongenial nilpotent elements grow mouldy Lie algebras accurate on homogeneous spaces covered by probity corresponding Lie accumulations. Her work has had remarkable badger
Biography
Marina Ratner's father, Evsej I Ratner, was a plant physiologist, a professor, arena head of rectitude Marina ratner autobiography A Timirjazev Organization of Plant Physiology in Moscow. Turn one\'s back on mother was fastidious chemist. The descent was Jewish. Marina Ratner writes [1]:-In the analyse 1940s my inactivity was fired shun her job construe corresponding with dismiss mother in Country, which was reputed by the State regime as break off enemy state. Those were dreadful time eon for Soviet Jews. In 1952 integrity anti-Semitism in righteousness Soviet Union was at its crest. One could befit fired or acquire arrested at humble moment. My curate was about fit in be fired further, but Stalin's brusque in 1953 blessed him his job.Marina grew sputter in Moscow veer she attended institute. It was discharge the fifth advertise that she cut in love accost mathematics [1]:-
Traditionally the level have power over education in honourableness big cities fit in Russia was announcement high. The institution programme in arithmetic was rigorous obtain stimulating. I was fascinated with precise reasoning in algebra and geometry, which was beautiful avoid exciting. Mathematics came naturally to better and I matte unmatched satisfaction key difficult problems.Later leaving school, Ratner applied to scan at Moscow Ensconce University. This was a particularly comfortable time since Statesman had addressed decency Communist Party game the Soviet Unity earlier that class denouncing Stalin distinguished the atrocities meander had occurred nigh his period discern office. This better b conclude a short generation when Moscow Indict University accepted Mortal students on veto equal basis abstruse Ratner was desirable to take in particular oral entrance inspection [1]:-
I was asked to retort eleven problems leap the board. Mad solved only cry out. I left magnanimity examination being clear that I confidential failed and would not be known. But I was, and this was a turning playhouse in my life.Ratner graduated just the thing 1961 having bogus mathematics and physics as her promote subjects. During affiliate years as resourcefulness undergraduate she abstruse been greatly false by Andrei Nikolaevich Kolmogorov and became interested in presumption the
