Mathematics

Shafarevich made fundamental contributions to several parts of mathematics including algebraic number theory, algebraic geometry and arithmetic algebraic geometry. In algebraic number theory, the Shafarevich–Weil theorem extends the commutative reciprocity map to the case of Galois groups, which are extensions of abelian groups by finite groups.

Shafarevich was the first to give a completely self-contained formula for the pairing, which coincides with the wild Hilbert symbol on local fields, thus initiating an important branch of the study of explicit formulas in number theory. Another famous result is Shafarevich's theorem on solvable Galois groups, giving the realization of every finite solvable group as a Galois group over the rationals. Another fundamental result is the Golod–Shafarevich theorem on towers of unramified extensions of number fields.

Shafarevich and his school greatly contributed to the study of algebraic geometry of surfaces. He initiated a Moscow seminar on classification of algebraic surfaces that updated the treatment of birational geometry around 1960 and was largely responsible for the early introduction of the scheme theory approach to algebraic geometry in the Soviet school. His investigation in arithmetic of elliptic curves led him, independently of John Tate, to the introduction of the most mysterious group related to elliptic curves over number fields, the Tate–Shafarevich group (usually called 'Sha', written 'Ш', his Cyrillic initial). He introduced the Grothendieck–Ogg–Shafarevich formula and the Néron–Ogg–Shafarevich criterion. He also formulated the Shafarevich conjecture, which stated the finiteness of the set of Abelian varieties over a number field having fixed dimension and prescribed set of primes of bad reduction. The conjecture was proved by Gerd Faltings as a step in his proof of the Mordell conjecture.

Shafarevich was a student of Boris Delaunay, and his students included Yuri Manin, Alexey Parshin, Igor Dolgachev, Evgeny Golod, Alexei Kostrikin, Igor A. Kostrikin, Suren Arakelov, G. V. Belyi, Victor Abrashkin, Andrey N. Tyurin, and Victor Kolyvagin. He did major work in collaboration with Ilya Piatetski-Shapiro on K3 surfaces. He was a member of the Serbian Academy of Sciences and Arts in the department of Mathematics, Physics and Earth Sciences. In 1960, he was elected a Member of the German Academy of Sciences Leopoldina.[3] In 1981, he was elected as a foreign member of the Royal Society.[4]

On his 80th birthday, Russian President Vladimir Putin hailed his "fundamental research" in mathematics and his creation of "a great science school known both in Russia and abroad".[5]

In 2017, Shafarevich was awarded the Leonard Euler Gold Medal by the Russian Academy of Sciences.

Soviet politics

Shafarevich came into conflict with the Soviet authorities in the early 1950s but was protected by Ivan Petrovsky, the Rector of Moscow University. He belonged to a group of Pochvennichestvo-influenced dissidents who endorsed the Eastern Orthodox tradition. Shafarevich published a book, The Socialist Phenomenon (French edition 1975, English edition 1980), which was cited by Aleksandr Solzhenitsyn in his 1978 address to Harvard University.

In the 1970s, Shafarevich, with Valery Chalidze, Grigori Podyapolski and Andrei Tverdokhlebov, became one of Andrei Sakharov's human rights investigators and so was dismissed from Moscow University. Shafarevich opposed political interference in universities. The algebraic geometer Miles Reid gave the example of Shafarevich in asserting that plagiarism and poor work were ignored in a doctorate that was obtained by a Communist Party functionary.

The Socialist Phenomenon

Shafarevich's book The Socialist Phenomenon,[6] which was published in the US by Harper & Row in 1980, analyzed numerous examples of socialism from ancient times to various medieval heresies and a variety of modern thinkers and socialist states. From those examples, he claimed that all the basic principles of socialist ideology derive from the urge to suppress individualism. The Socialist Phenomenon consists of three major parts:[7]

  1. Chiliastic Socialism: Identifies socialist ideas amongst the ancient Greeks, especially Plato, in numerous medieval heretic groups such as the Cathars, Brethren of the Free Spirit, Taborites, Anabaptists, in various religious groups during the English Civil War, in modern writers such as Thomas More, Tommaso Campanella and numerous Enlightenment writers in 18th-century France.[8]
  2. State Socialism: Describes the socialism of the Incas, the Jesuit state in Paraguay, Mesopotamia, Egypt and China.[9]
  3. Analysis: Identifies three persistent abolition themes in socialism: the abolition of private property, the abolition of the family, and the abolition of religion (mainly but not exclusively Christianity)[10]

Shafarevich argued that ancient socialism (such as Mesopotamia and Egypt) was not ideological, as an ideology socialism was a reaction to the emergence of individualism in the Axial Age. He compared Thomas More's (Utopia) and Tommaso Campanella's (City of the Sun) visions with what is known about the Inca Empire and concluded that there are striking similarities. He claimed that we become persons through our relationship with God and argued that socialism is essentially nihilistic and is unconsciously motivated by a death instinct. He concluded that we have the choice of pursuing death or life.

Religious views

Shafarevich adhered to Russian Orthodox Christianity and incorporated the neo-Platonic views of Eastern Orthodoxy into his understanding of the relation of mathematics and religion.[11]

In his talk to the Göttingen Academy of Sciences upon receiving a prize, Shafarevich presented his view of the relationship between mathematics and religion. He noted the multiple discoveries in mathematics, such as that of non-Euclidean geometry, to suggest that pure mathematics reflects an objective reality, not a set of conventional definitions or a formalism. He claimed that the growth of mathematics itself is not directed or organic. To have a unity and direction, mathematics needs a goal. It can be practical applications or God as the source for the direction of development. Shafarevich opted for the latter, as pure mathematics is not in itself driven by practical applications.[12]

Russian politics

On 21 December 1991 he took part in the first congress of the Russian All-People's Union, headed by Sergei Baburin. In October 1992, he became a member of the founding committee of the National Salvation Front. In 1993, he was an unsuccessful candidate for the State Duma with Mikhail Astafyev's Constitutional Democratic Party - Party of Popular Freedom.

Shafarevich was a member of the editorial board of the magazine Nash Sovremennik and in 1991–1992 of the editorial board of Den of Alexander Prokhanov, which ceased publication in October 1993 and later reopened under the title Zavtra. In 1994, he joined the "All-Russian National Right Wing Centre", led by Mikhail Astafyev.

Accusations of anti-Semitism

Shafarevich's essay Russophobia[13] was expanded into his book Three Thousand-Year-Old Mystery (Трехтысячелетняя загадка) and resulted in accusations of anti-Semitism.[14][15][16] He completed the Russophobia essay in 1982 and it was initially circulated as samizdat. In the Soviet Union, it was first officially published in 1989.

In Russophobia, he argued in the essay that great nations experience periods in their history of reformist elitist groups ('small nations') having values that differ fundamentally from the values of the majority of the people but gaining the upper hand in the society. In Shafarevich's opinion, the role of such a 'small nation' in Russia was played by a small group of intelligentsiya, dominated by Jews, who were full of hatred against traditional Russian way of life and played an active role in the terrorist regimes of Vladimir Lenin and Joseph Stalin.[17][18]

Its publication led to a request by the United States National Academy of Sciences (NAS) to Shafarevich to resign his membership,[19] because the NAS charter prohibited stripping an existing membership.[20][21] In an open letter to the NAS, Shafarevich denied that Russophobia is anti-Semitic.[22] Shafarevich also noted that since NAS enlisted him without his request or knowledge, delisting him was its internal matter. Nevertheless, when the United States invaded Iraq, Shafarevich faxed his resignation.[23]

Accusations of anti-Semitism continued and involved Shafarevich's other publications.[24] Semyon Reznik targets the Russophobia essay for alleged factual inaccuracies: Shafarevich misassigned Jewish ethnicity to a number of non-Jewish individuals involved in the execution of Nicholas II, perpetuated the false assertion of graffiti in Yiddish at the murder site and suggested that Shafarevich's phrase "Nicholas II was shot specifically as the Tsar, and this ritual act drew a line under an epoch in Russian history" – may be read as a blood libel.[17] (The accusation ignores the remainder of Shafarevich's sentence: "so it can only be compared with the execution of Charles I in England or of Louis XVI in France".)[13] Aron Katsenelinboigen, wrote that Shafarevish's work "lives up to the best traditions of antisemitic propaganda".[25]

Later, Shafarevich expanded on his views in his book Three Thousand-Year-Old Mystery in which he further claimed that Jews effectively marginalise non-Jews to the point of exclusion in all types of intellectual endeavors. The work was published in Russian in 2002; an introductory section explains the relationship with the Russophobia essay, explaining that the essay developed from an appendix to an intended work of wider scope, which he started writing in samizdat.[26]

The issue of Shafarevich's alleged anti-Semitism has been the subject of a 2009 doctoral thesis at the University of Helsinki, which was later turned into a book[1] in which the author, Krista Berglund, concluded that Shafarevich's views have been misconstrued as anti-Semitic.
