Vladimir Gilelevich Maz'ya (Russian: Владимир Гилелевич Мазья; born December 31, 1937)[1][2][3] (the family name is sometimes transliterated as Mazya, Maz'ja or Mazja) is a Russian-born Swedish mathematician, hailed as "one of the most distinguished analysts of our time"[4] and as "an outstanding mathematician of worldwide reputation",[5] who strongly influenced the development of mathematical analysis and the theory of partial differential equations.[6][7] His early achievements include: his work on Sobolev spaces, in particular the discovery of the equivalence between Sobolev and isoperimetric/isocapacitary inequalities (1960),[8] his counterexamples related to Hilbert's 19th and Hilbert's 20th problem (1968),[9] his solution, together with Yuri Burago, of a problem in harmonic potential theory (1967) posed by Riesz & Nagy (1955, chapter V, § 91), his extension of the Wiener regularity test to p–Laplacian and the proof of its sufficiency for the boundary regularity.[10] Maz'ya solved V. Arnol'd's problem for the oblique derivative boundary value problem (1970) and to F. John's problem on the oscillations of a fluid in the presence of an immersed body (1977). In recent years, he proved a Wiener's type criterion for higher order elliptic equations, together with M. Shubin solved a problem in the spectral theory of the Schrödinger operator formulated by Israel Gelfand in 1953,[11] found necessary and sufficient conditions for the validity of maximum principles for elliptic and parabolic systems of PDEs and introduced the so–called approximate approximations. He also contributed to the development of the theory of capacities, nonlinear potential theory, the asymptotic and qualitative theory of arbitrary order elliptic equations, the theory of ill-posed problems, the theory of boundary value problems in domains with piecewise smooth boundary.

Biography

[edit]

Life and academic career

[edit]

Vladimir Maz'ya was born on 31 December 1937[2] in a Jewish family.[12] His father died on December 1941 at the World War II front,[2][12][13] and all four grandparents died during the siege of Leningrad.[2][12] His mother, a state accountant,[14] chose to not remarry and dedicated her life to him:[12] they lived on her meager salary in a 9 square meters room in a big communal apartment, shared with other four families.[12][15] As a secondary school student, he repeatedly won the city's mathematics and physics olympiads[16] and graduated with a gold medal.[17]

In 1955, at the age of 18, Maz'ya entered the Mathematics and Mechanics Department of Leningrad University.[18] Taking part to the traditional mathematical olympiad of the faculty, he solved the problems for both first year and second year students and, since he did not make this a secret, the other participants did not submit their solutions causing the invalidation of the contest by the jury which therefore did not award the prize.[13] However, he attracted the attention of Solomon Mikhlin who invited him at his home, thus starting their lifelong friendship:[13] and this friendship had a great influence on him, helping him develop his mathematical style more than anyone else. According to Gohberg (1999, p. 2),[19] in the years to come, "Maz'ya was never a formal student of Mikhlin, but Mikhlin was more than a teacher for him. Maz’ya had found the topics of his dissertations by himself, while Mikhlin taught him mathematical ethics and rules of writing, referring and reviewing".[20]

More details on the life of Vladimir Maz'ya, from his birth to the year 1968, can be found in his autobiography (Maz'ya 2014).

Maz'ya graduated from Leningrad University in 1960.[1][21] The same year he gave two talks at Smirnov's seminar:[22] their contents were published as a short report in the Proceedings of the USSR Academy of Sciences[23][24] and later evolved in his "kandidat nauk" thesis, "Classes of sets and embedding theorems for function spaces",[25] which was defended in 1962.[26] In 1965 he earned the Doktor nauk degree in 1965, again from Leningrad University, defending the dissertation "Dirichlet and Neumann problems in Domains with irregular boundaries", when he was only 27.[27] Neither the first nor his second thesis were written under the guidance of an advisor: Vladimir Maz'ya never had a formal scientific adviser, choosing the research problems he worked to by himself.[28]

From 1960 up to 1986, he worked as a "research fellow"[29] at the Research Institute of Mathematics and Mechanics of Leningrad University (RIMM), being promoted from junior to senior research fellow in 1965.[30] From 1968 to 1978 he taught at the Leningrad Shipbuilding Institute, where he was awarded the title of "professor" in 1976.[31] From 1986 to 1990 he worked to the Leningrad Section of the Blagonravov Research Institute of Mechanical Engineering of the USSR Academy of Sciences,[32] where he created and directed the Laboratory of Mathematical Models in Mechanics and the Consulting Center in Mathematics for Engineers.[33]

In 1978 he married Tatyana Shaposhnikova, a former doctoral student of Solomon Mikhlin, and they have a son, Michael:[34] In 1990, they left the URSS for Sweden, where Prof. Maz'ya obtained the Swedish citizenship and started to work at Linköping University.[35]

Currently, he is honorary Senior Fellow of Liverpool University and Professor Emeritus at Linköping University: he is also member of the editorial board of several mathematical journals.[36]

Honors

[edit]

In 1962 Maz'ya was awarded the "Young Mathematician" prize by the Leningrad Mathematical Society, for his results on Sobolev spaces:[25] he was the first winner of the prize.[23] In 1990 he was awarded an honorary doctorate from Rostock University.[37] In 1999, Maz'ya received the Humboldt Prize.[37][38] He was elected member of the Royal Society of Edinburgh in 2000,[39] and of the Swedish Academy of Science in 2002.[37] On March 2003 He, jointly with Tatyana Shaposhnikova, was awarded the Verdaguer Prize by the French Academy of Sciences.[40] On 31 August 2004 he was awarded the Celsius Gold Medal, the Royal Society of Sciences in Uppsala's top award, "for his outstanding research on partial differential equations and hydrodynamics".[41] He was awarded the Senior Whitehead Prize by the London Mathematical Society on the 20th of November 2009.[42] In 2012 he was elected fellow of the American Mathematical Society.[43] On October 30, 2013 he was elected foreign member of the Georgian National Academy of Sciences.[44]

Starting from 1993, several conferences have been held to honor him: the first one, held in that year at the University of Kyoto, was a conference on Sobolev spaces.[45] On the occasion of his 60th birthday in 1998, two international conferences were held in his honor: the one at the University of Rostock was on Sobolev spaces,[45][46] while the other, at the École Polytechnique in Paris,[45][47] was on the boundary element method. He was invited speaker at the International Mathematical Congress held in Beijing in 2002:[37] his talk is an exposition on his work on Wiener–type criteria for higher order elliptic equations. Other two conferences were held on the occasion of his 70th birthday: "Analysis, PDEs and Applications on the occasion of the 70th birthday of Vladimir Maz'ya" was held in Rome,[48] while the "Nordic – Russian Symposium in honour of Vladimir Maz'ya on the occasion of his 70th birthday" was held in Stockholm.[49] On the same occasion, also a volume of the Proceedings of Symposia in Pure Mathematics was dedicated to him.[50]

Work

[edit]

Research activity

[edit]

Because of Maz’ya’s ability to give complete solutions to problems which are generally considered as unsolvable, Fichera once compared Maz’ya with Santa Rita, the 14th century Italian nun who is the Patron Saint of Impossible Causes.

— Alberto Cialdea, Flavia Lanzara and Paolo Emilio Ricci, (Cialdea, Lanzara & Ricci 2009, p. xii).

Maz'ya authored/coauthored more than 500 publications, including 20 research monographs: several survey articles on his work can be found in the book (Rossmann, Takáč & Wildenhain 1999a), and also the paper by Dorina and Marius Mitrea (2008) describes extensively his research achievements.
