Question: Was Stanislav Smirnov or Grigori Perelman awarded the Fields Medal in 2010?
Context: The Wolf Prize in Mathematics is awarded almost annually by the Wolf Foundation in Israel.  It is one of the six Wolf Prizes established by the Foundation and awarded since 1978; the others are in Agriculture, Chemistry, Medicine, Physics and Arts.  Until the establishment of the Abel Prize, the Prize was probably the closest equivalent of a "Nobel Prize in Mathematics", since the Fields Medal is awarded every four years only to mathematicians under the age of 40. Grigori Yakovlevich Perelman (Russian: Григо́рий Я́ковлевич Перельма́н ; ] ; born 13 June 1966) is a Russian mathematician.  He made a contribution to Riemannian geometry and geometric topology. Gregori Aleksandrovich Margulis (Russian: Григо́рий Алекса́ндрович Маргу́лис , first name often given as Gregory, Grigori or Grigory; born February 24, 1946) is a Russian-American mathematician known for his work on lattices in Lie groups, and the introduction of methods from ergodic theory into diophantine approximation.  He was awarded a Fields Medal in 1978 and a Wolf Prize in Mathematics in 2005, becoming the seventh mathematician to receive both prizes.  In 1991, he joined the faculty of Yale University, where he is currently the Erastus L. De Forest Professor of Mathematics. In mathematics, the soul theorem is a theorem of Riemannian geometry that largely reduces the study of complete manifolds of non-negative sectional curvature to that of the compact case.  Cheeger and Gromoll proved the theorem in 1972 by generalizing a 1969 result of Gromoll and Wolfgang Meyer.  The related soul conjecture was formulated by Gromoll and Cheeger in 1972 and proved by Grigori Perelman in 1994 with an astonishingly concise proof. "Manifold Destiny" is an article in "The New Yorker" written by Sylvia Nasar and David Gruber and published in the August 28, 2006 issue of the magazine.  It claims to give a detailed account (including interviews with many mathematicians) of some of the circumstances surrounding the proof of the Poincaré conjecture, one of the most important accomplishments of 20th and 21st century mathematics, and traces the attempts by three teams of mathematicians to verify the proof given by Grigori Perelman. Stanislav Konstantinovich Smirnov (Russian: Станисла́в Константи́нович Cмирно́в ; born 3 September 1970) is a Russian mathematician currently working at the University of Geneva.  He was awarded the Fields Medal in 2010.  His research involves complex analysis, dynamical systems and probability theory. Fischer Black Prize is a memorial prize awarded in honor of Fischer Black that rewards individual financial research.  The prize was established in 2002 and first awarded in 2003.  It is awarded to a financial scientist for a body of work that demonstrates significant original research that is relevant to finance practice.  Eligible scholars must either be below 40 years in age, or under age 45 but not have been awarded a Ph.D. (or equivalent) by age 35.  The prize is awarded biennially at the American Finance Association's Annual Meeting.  This award to honor a leading young finance scholar is analogous to the John Bates Clark Medal in economics and the Fields Medal in mathematics. John Charles Fields, FRS, FRSC (May 14, 1863 – August 9, 1932) was a Canadian mathematician and the founder of the Fields Medal for outstanding achievement in mathematics.  First awarded in 1936, the medal has been awarded since 1950 every four years at the International Congress of Mathematicians to two, three or four recipients under the age of 40. David Bryant Mumford (born 11 June 1937) is an American mathematician known for distinguished work in algebraic geometry, and then for research into vision and pattern theory.  He won the Fields Medal and was a MacArthur Fellow.  In 2010 he was awarded the National Medal of Science.  He is currently a University Professor Emeritus in the Division of Applied Mathematics at Brown University. The Fields Medal Symposium is an annual event that honours one of the Fields Medal recipients from the most recent International Congress of Mathematicians.  The symposium is jointly endorsed by the International Mathematical Union and the Fields Institute for Mathematical Sciences.  The idea was conceived in preparation for the International Congress of Mathematicians 2010 (ICM2010) in Hyberdad, India.  Professor Edward Bierstone of the University of Toronto was the director of the institute during the inaugural symposium in October 2012.  All symposiums take place at the Fields Institute in Toronto, Canada.  The symposia include mathematical activity that explore work related to the honoured Fields Medallist.  They will include public lectures meant to spark interest in mathematics including public lectures and events for students.
