Victor Petrovich Havin: Life and Works Seminar Overview
Victor Petrovich Havin, a renowned mathematician, was born in 1933 in St. Petersburg. Despite facing challenges during World War II and the Soviet regime, he pursued his passion for mathematics and became a Professor at St. Petersburg University. His career included significant events such as Stalin's death, Khrushchev's destalinization, and participating in mathematical seminars. Havin's dedication to mathematics and teaching influenced numerous pupils. The narrative chronicles his academic journey, highlighting key milestones and historical contexts that shaped his life and career.

Victor Petrovich Havin: Life, Works, Seminar, and Pupils Presented by N.Nikolski, Euler Intl Institute, June 2016
Havins Outline: Born: March 7, 1933 (St.Petersburg) 1941-1945 - Havin s family survived from the collapse of WW II in evacuation at Tashkent (Uzbekistan) 1949 Soviet atomic bomb explosed 1950-1955 Havin: Student, Mathematics and Mechanics Department of St.Petersburg University (Photo: Havin, 1954)
Choice of Mathematics as a destiny: by political reasons
1953 Stalins death 1952-1953 KGB inspired Doctors-killers plot national hysteria, a new stage of the state antijews campaigne 1955-1958- Havin: Graduated studies at St.Petersburg University (under Vladimir Smirnov and Leonid Kantorovich, future Nobel Prize winner in economics) 1956 Nikita Khruschev s destalinization 1956 Soviet tanks ecrase Hungary revolution 1959 - Havin takes Ph.D. from SPb University 1961 Cuba crisis
1959 2015 Havin: Professor at St.Petersburg University (assistant 1959, associate 1962, full 1970-2015). (Photo: 1962; 1963 kolkhoz forced manual gratis work)
1962 Beginning of Havin s Analysis Seminar: - 1962 3 participants, - 1964 5 participants, - 1966 - 10, - 1970 25, - since 1980 more than 50
1968 Prague Spring (socialism with a human face ) and unworthy Soviet invasion 1974 Havin got his first permission to leave the country (inside the socialist camp ); Cuba (1974), Czechoslovakia (1976) At Charles University,1996(?) Soviet tanks in Prague, 1968
1991 break-down of the Soviet Union deserting the seminar rooms and student classes Boris Eltsin on a tank, August 1991 At a separation point: May 1991, before last joint seminar
1993 Havin received Doctor Honoris Causa degree at Link ping University 1993-2003 Havin: teaching at McGill University Link ping ceremony During a break between lectures, McGill U. (Havin, P.Koosis, S.Smirnov)
1996 Spenser Lecturer at Kansas State University 2000 The Onsager Professor at Trondheim University 2003 Distinguish Researcher of the R.F. 2011 Chebyshev Prize of St.Petersburg City Counsil
Starting Point: Havin as an autodidact: there was an analysis school - V.I.Smirnov, G.Fichtenholtz, L.Kantorovich, G.Akilov, and
Starting Point: Havin as an autodidact: and V.Havin, a Ph.D. student (1955-1958) with a suggestion of a free choice of research subject Fast evolution from soft to hard Analysis
Havins Favorite Fields: I. Yearly Years - Genre Searching (Separation of singularities, Golubev series, Fourier coefficients of bounded functions, and so on)
II. Rational Approximation III. Principle of Half-Smoothness of a holomorphic F vs |F| IV. Non-linear Potential Theory, in longlasting collaboration with V.Maz ya V. Weak Completeness of L /H
VI. Uncertainty Principle in Harmonic Analysis (with V.Maz ya, B.J ricke, F.Nazarov, E.Malinnikova J.Mashreghi, A.Baranov, et al.) Ufa conference in approximation theory, 1980
VII. Cauchy Problem for Laplacian (with V.Mazya, A.Aleksandrov, J.Bourgain, et al.) VIII. Approximation by Harmonic Vector Fields (with E.Malinnikova, S.Smirnov, et al.) IX. Admissible Majorants for Model (deBranges) Spaces (with J.Mashreghi, Yu.Lyubarsky, A.Baranov, et al.)
Havins Seminar, and Havin s Pupils
Founding one of the World Largest Analysis Seminars: Ph.D. defended under Havin : 31 - Including 3 Salem Prize winners A.Aleksandrov, F.Nazarov, S.Smirnov
Havins Exceptional Achievement: Creation of a Highly Active Analysis Community around the Hardy Space Ideology Havin s Scientific descendants, following Math Genealogy Project: 139 - - Including 9 Salem Prize winners: three above, and then A.Volberg, S.Treil, N.Makarov, S.Petermichl, Zhen Dapeng, D.Chelkak, - Including Fields Medal of Stas Smirnov (Havin s math great-grandson)
Notable Visitors/Seminar Speakers included: H.Shapiro, A.Shields, Y.Domar, P.Duren, P.Koosis, P.Gauthier, J.Conway, J.M.Anderson, L.Hedberg, M.Essen, L.deBranges (1984, solving at place the Bieberbach Conjecture), Ch.Davis, L.Ehrenpreis, J- P Kahane, G.Pisier, D.Sarason, J.Korevaar, R.Rochberg, B.Fuglede, E.Amar, C.Berenstein,
A few milestone results: 1980: Smooth Hankel Operators (V.Peller) 1982: Inner Functions in (A.Aleksandrov) 1985: LogLog law for conformal mappings (N.Makarov) 1988, 2002-2014: Matrix /Operator Corona Problem (Sz.-Nagy problem, etc) , S.Treil 1996 2015: The Bellman Function Method (F.Nazarov, S.Treil, A.Volberg)
Milestone results, contd: 1997 2004: Calderon-Zygmund Operators on nonhomogeneous spaces (F.Nazarov, S.Treil, A.Volberg, S.Petermichl) 1987-2015: Model and DeBranges Spaces (A.Aleksandrov, V.Havin, J.Mashreghi, N.Makarov, A.Poltoratskii, A.Baranov)
Remembering Victor Petrovich Havin A God-given mentor never suppressed his pupils, neither by his own learning nor by galloping, but teaching by a passion inspiring V.P. s sayings on his beloved pure Analysis: a technical crawled analysis , but analysis techniques should be always ready as keeping powder dry Much influenced by G.Hardy s A Mathematician s Apology
Havins currently speaking phrases: Walk to Canossa (or Humiliation of Canossa ), as Henry IV to Pope Gregory VII, 1077 when coming to get a permission for having a jew student, or for a PhD defence overcoming the 2/5 rule Never beg for nothing, especially from those who is stronger than you (Woland to Margarita)
Remembering Havin Propheting the main streams in Analysis since 1960, in particular the Hardy spaces obsession/philosophy which celebrate 100 years in 2015, and 50 years in Havin s Seminar An incomparably emotional leader involving everybody just by his own implication, never pressing by the authority A very rare unmercenary who never understood what the money is Natural, artless Stoic (in front of the life hardness, including unprecedented insults against the Jewish self-identity during the Soviet era)
