Question: Who is older, Aleksandr Danilovich Aleksandrov or Anatoly Fomenko?
Context: The Alexandrov uniqueness theorem is a rigidity theorem in mathematics, describing three-dimensional convex polyhedra in terms of the distances between points on their surfaces.  It implies that convex polyhedra with distinct shapes from each other also have distinct metric spaces of surface distances, and it characterizes the metric spaces that come from the surface distances on polyhedra.  It is named after Soviet mathematician Aleksandr Danilovich Aleksandrov, who published it in the 1940s. Alexander Grinberg (Александр Данилович Гринберг, Aleksandr Danilovich Grinberg) (1885–1979) was a Russian and Soviet photographer.  n 1908 he was awarded the silver medal in the all-Russian photo exhibition in Moscow and the gold medal in the international photo-exhibition in Dresden. The New Chronology is a pseudohistorical theory which argues that the conventional chronology of Middle Eastern and European history is fundamentally flawed, and that events attributed to the civilizations of the Roman Empire, Ancient Greece and Ancient Egypt actually occurred during the Middle Ages, more than a thousand years later.  The central concepts of the New Chronology are derived from the ideas of Russian scholar Nikolai Morozov (1854–1946), although work by French scholar Jean Hardouin (1646–1729) can be viewed as an earlier predecessor.  However, the New Chronology is most commonly associated with Russian mathematician Anatoly Fomenko (born 1945), although published works on the subject are actually a collaboration between Fomenko and several other mathematicians.  The concept is most fully explained in "History: Fiction or Science?" , originally published in Russian. The Battle of Lesnaya (Russian: Битва при Лесной "Bitva pri Lesnoy", Swedish: "Slaget vid Lesna" , Polish: "Bitwa pod Leśną" ), was one of the major battles of the Great Northern War.  It took place on September 28, 1708 (O.S.) / September 29, 1708 (Swedish calendar) / October 9, 1708 (N.S.) between a Russian army of between 26,500 and 29,000 men commanded by Peter I of Russia, Mikhail Mikhailovich Golitsyn, Aleksandr Danilovich Menshikov, Christian Felix Bauer and Nikolai Grigorovitj von Werden and a Swedish army of about 12,500 men commanded by Adam Ludwig Lewenhaupt and Berndt Otto Stackelberg, at the village of Lesnaya, located close to the border between the Polish–Lithuanian Commonwealth and Russia (now the village of Lyasnaya, south-east of Mogilev in Belarus).  The Swedes were escorting a supply column of more than 4,500 wagons for their main army in Ukraine. Anatoly Timofeevich Fomenko (Russian: Анато́лий Тимофе́евич Фоме́нко ) (born 13 March 1945 in Stalino, USSR) is a Soviet and Russian mathematician, professor at Moscow State University, well known as a topologist, and a member of the Russian Academy of Sciences.  He is author of a pseudoscientific theory known as New Chronology.  He is also a member of the Russian Academy of Natural Sciences (1991). Aleksandr Danilovich Aleksandrov (Russian: Алекса́ндр Дани́лович Алекса́ндров , alternative transliterations: "Alexandr" or "Alexander" (first name), and "Alexandrov" (last name)) (August 4, 1912 – July 27, 1999), was a Soviet/Russian mathematician, physicist, philosopher and mountaineer. The theory of isometries in the framework of Banach spaces has its beginning in a paper by Stanisław Mazur and Stanisław M. Ulam in 1932.  They proved that each isometry of a normed real linear space onto a normed real linear space is a linear mapping up to translation.  In 1970, Aleksandr Danilovich Aleksandrov asked whether the existence of a single conservative distance for some mapping implies that it is an isometry.  Themistocles M. Rassias posed the following problem: The Battle of Oposhnya was a battle which took place on February 8, 1709 during the Swedish invasion of Russia in the Great Northern War.  After the costly siege of Veprik the Swedes under Charles XII of Sweden started an offensive against the Russian army in the area.  The intention of this offensive was not clear to the Russians, as they subsequently had to spread their main forces out to cover possible attack directions.  One of these were the troops under Aleksandr Danilovich Menshikov positioned at Oposhnya on the river Vorskla to block any attempt by the Swedes to cross the river.  Charles intended to attack Menshikov and his 6,000 cavalry in a surprising manner, forcing them off the location.  He led 2,000 cavalry for this task and managed to catch the Russians completely by surprise while having dinner.  Charles immediately charged with his men and swept the Russian forces out of the town followed by a hot pursuit on step.  In this action the Russians lost more than 450 men, the Swedes only 19.  Perhaps more importantly however, the Swedes could now cross the river Vorskla.  The offensive continued for a while and Charles reached Krasnokutsk where he forced another Russian army on the run. In mathematical analysis, the Alexandrov theorem, named after Aleksandr Danilovich Aleksandrov, states that if U is an open subset of R and  "f" : "U" → R   is a convex function, then "f" has a second derivative almost everywhere. Princess Maria Alexandrovna Menshikova (26 December 1711 – 1729) was a daughter of Aleksandr Danilovich Menshikov, the favourite of Peter I of Russia.
