Question: Are Sofia Kovalevskaya and Anatoly Maltsev both mathematicians?
Context: Sofia Vasilyevna Kovalevskaya (Russian: Со́фья Васи́льевна Ковале́вская ), born Sofia Vasilyevna Korvin-Krukovskaya (1850–1891), was a Russian mathematician who made noteworthy contributions to analysis, partial differential equations and mechanics.  She was the first major Russian female mathematician and a pioneer for women in mathematics around the world.  She was the first woman appointed to a full professorship in Northern Europe and was also one of the first women to work for a scientific journal as an editor.  Her sister was the socialist Anne Jaclard. Anatoly Ivanovich Maltsev (also: Malcev, Mal'cev; Russian: Анато́лий Ива́нович Ма́льцев; 27 November N.S./14 November O.S. 1909, Moscow Governorate – 7 June 1967, Novosibirsk) was born in Misheronsky, near Moscow, and died in Novosibirsk, USSR.  He was a mathematician noted for his work on the decidability of various algebraic groups. Malcev algebras (generalisations of Lie algebras) are named after him. Tricia Striano was born in Weymouth Massachusetts.  She obtained her BA in psychology from The College of the Holy Cross.  She obtained her Ph.D. in Psychology from Emory University in 2000, after which she became Head of the Independent Research Group on Cultural Ontogeny at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.  In 2004, Tricia Striano received the Sofia Kovalevskaya Award  of the Alexander von Humboldt Foundation.  She used the award to build the Neurocognition and Development Group at the Max Planck Institute for Human Cognitive and Brain Sciences and Center for Advanced Studies at the University of Leipzig.  In 2008, Dr. Striano obtained her habilitation from the University of Osnabruck in Germany.  Dr. Striano is currently a Professor in the Department of Psychology at Hunter College, City University of New York. Kovalevskaya is a prominent lunar impact crater that is located on the far side of the Moon.  It lies to the southwest of the larger walled plain Landau.  To the south of Kovalevskaya are the craters Poynting and Fersman. The Alexander von Humboldt Foundation of Germany bestows the Sofia Kovalevskaya Award every two years.  Sofia Kovalevskaya (1850–1891) was the first major Russian female mathematician, who made important contributions to mathematical analysis, differential equations and mechanics, and the first woman appointed to a full professorship in Northern Europe.  This prestigious award named in her honor is given to promising young academics to pursue their line of research in the sciences or arts and humanities.  The foundation encourages applications from all areas of the academy so long as the investigator received a Ph.D. in the last six years and may be categorized as "top flight" by their publications and experience as commensurate with age. In mathematics, Hahn series (sometimes also known as Hahn–Mal'cev–Neumann series) are a type of formal infinite series.  They are a generalization of Puiseux series (themselves a generalization of formal power series) and were first introduced by Hans Hahn in 1907 (and then further generalized by Anatoly Maltsev and Bernhard Neumann to a non-commutative setting).  They allow for arbitrary exponents of the indeterminate so long as the set supporting them forms a well-ordered subset of the value group (typically formula_1 or formula_2).  Hahn series were first introduced, as groups, in the course of the proof of the Hahn embedding theorem and then studied by him as fields in his approach to Hilbert's seventeenth problem. Anne Jaclard, born Anna Vasilyevna Korvin-Krukovskaya (1843–1887), was a Russian socialist and feminist revolutionary.  She participated in the Paris Commune and the First International and was a friend of Karl Marx.  She was once engaged to Fyodor Dostoyevsky but married the Blanquist Victor Jaclard.  Her sister was the mathematician and socialist Sofia Kovalevskaya (1850–1891). Eugene Demjanovich Maltsev (Russian: Евгений Демьянович Мальцев ; August 9, 1929, Ryazan Oblast, USSR — December 24, 2003, Saint Petersburg, Russia) was a Soviet Russian painter, People's Artist of the Russian Federation, a member of the Saint Petersburg Union of Artists (before 1992 — the Leningrad Union of the Soviet Artists), who lived and worked in Leningrad.  In 1990-1997 Eugene Maltsev was a head of the Saint Petersburg Union of Artists, in 1989-1991 was elected a People's Deputies of the Soviet Union from the USSR Union of Artists.  Maltsev regarded as one of representatives of the Leningrad school of painting, most famous for his portrait and historical paintings. Bobone is an old, heavily eroded crater formation that lies on the far side of the Moon.  Little remains of the original crater formation, leaving only a bowl-shaped depression in the surface that is pock-marked by tiny craterlets.  It is attached to the southwest rim of the large satellite crater Kovalevskaya Q, which has its northeast rim overlaid by Kovalevskaya itself.  To the west-southwest is Bronk. Olga Holtz (Russian: Ольга Гольц ; born August 19, 1973) is a Russian mathematician specializing in numerical analysis.  She received the Sofia Kovalevskaya Award in 2006 and the European Mathematical Society Prize (2008).  Since 2008, she is a member of the Young Academy (Junge Akademie"") of Germany.
