American mathematician (1943–2022)
Lawrence Allen Zalcman (June 9, 1943 – May 31, 2022) was a professor (and later a professor
emeritus ) of Mathematics at
Bar-Ilan University in
Israel . His research primarily concerned
Complex analysis ,
potential theory , and the relations of these ideas to
approximation theory ,
harmonic analysis ,
integral geometry and
partial differential equations .
[1]
[2] On top of his scientific achievements, Zalcman received numerous awards for mathematical exposition, including the
Chauvenet Prize
[3] in 1976, the
Lester R. Ford Award in 1975
[3] and 1981,
[4] and the
Paul R. Halmos – Lester R. Ford Award in 2017.
[5] In addition to Bar-Ilan University, Zalcman taught at the
University of Maryland and
Stanford University in the United States.
[6]
Life and career
Zalcman was born in
Kansas City, Missouri on June 9, 1943.
[6] In 1961, he graduated from
Southwest High School in
Kansas City, Missouri before continuing his education at
Dartmouth College , where he would graduate in 1964.
[6] Zalcman went on to receive his Ph.D. from the
Massachusetts Institute of Technology in 1968 under the supervision of
Kenneth Myron Hoffman .
[7] In 2012, Zalcman became a fellow of the
American Mathematical Society .
[8]
In the theory of normal families,
Zalcman's Lemma , which he used as part of his treatment of
Bloch's principle , is named after him.
[9] Other eponymous honors are
Zalcman domains , which play a role in the classification of
Riemann surfaces , and
Zalcman functions in complex dynamics. In the theory of partial differential equations, the
Pizzetti-Zalcman formula is partially named after him.

Lawrence Zalcman died in
Jerusalem on May 31, 2022.
