Joram Lindenstrauss ({{langx|he|יורם לינדנשטראוס}}) (October 28, 1936 – April 29, 2012) was an Israeli mathematician working in functional analysis. He was a professor of mathematics at the Einstein Institute of Mathematics.[http://www.ma.huji.ac.il/staff/faculty_em.html Professors emeriti, Einstein Institute of Mathematics] {{Webarchive|url=https://web.archive.org/web/20240129193717/http://www.ma.huji.ac.il/staff/faculty_em.html |date=2024-01-29 }},

Biography

Joram Lindenstrauss was born in Tel Aviv. He was the only child of a pair of lawyers who immigrated to Israel from Berlin. He began to study mathematics at the Hebrew University of Jerusalem in 1954 while serving in the army. He became a full-time student in 1956 and received his master's degree in 1959. In 1962 Lindenstrauss earned his Ph.D. from the Hebrew University (dissertation: Extension of Compact Operators, advisors: Aryeh Dvoretzky, Branko Grünbaum).[http://genealogy.math.ndsu.nodak.edu/id.php?id=44237 Joram Lindenstrauss] at Mathematics Genealogy He worked as a postdoc at Yale University and the University of Washington in Seattle from 1962 - 1965. He was appointed senior lecturer at the Hebrew University in 1965, associate professor on 1967 and full professor in 1969. He became the Leon H. and Ada G. Miller Memorial Professor of Mathematics in 1985. He retired in 2005.

Lindenstrauss was married to theoretical computer scientist Naomi Lindenstrauss. Two of their children, Ayelet Lindenstrauss and Fields Medallist Elon Lindenstrauss, are also mathematicians (providing a rare example of father, mother, son and daughter all having papers listed in Mathematical Reviews).{{Cite web| title = Joram Lindenstrauss CV| url = https://www.emis.de/mirror/IMU/Elections_2002/EC/lindenstrausscv.pdf }} Joram was also the cousin of Micha Lindenstrauss.

Research

Lindenstrauss worked in various areas of functional analysis and geometry,[https://books.google.com/books?id=v9in9nUW5bsC&pg=PP4&vq=1936'&dq=%22Classical+Banach+Spaces%22&source=gbs_search_r&cad=1_1 A biographical sketch from the book "Classical Banach Spaces"] particularly Banach space theory, finite- and infinite-dimensional convexity, geometric nonlinear functional analysis and geometric measure theory. He authored more than 100 papers as well as several books in Banach space theory.{{cite web|title=MathSciNet author profile|url=https://www.ams.org/mathscinet/search/author.html?mrauthid=114270|url-access=subscription}}

Among his results is the Johnson–Lindenstrauss lemma which concerns low-distortion embeddings of points from high-dimensional into low-dimensional Euclidean space. Another of his theorems states that in a Banach space with the Radon–Nikodym property, a closed and bounded set has an extreme point; compactness is not needed.{{harvtxt|Artstein|1980|p=173}}: {{cite journal|last=Artstein|first=Zvi|title=Discrete and continuous bang-bang and facial spaces, or: Look for the extreme points|journal=SIAM Review|volume=22|year=1980|number=2|pages=172–185|doi=10.1137/1022026|mr=564562|jstor=2029960}}

Awards

In 1981 Lindenstrauss was awarded the Israel Prize, for mathematics.{{Cite web| title = Israel Prize Official Site - Recipients in 1981 (in Hebrew)| url = http://cms.education.gov.il/EducationCMS/Units/PrasIsrael/Tashlag/Tashmab_Tashlag_Rikuz.htm?DictionaryKey=Tashma}} In 1997, Lindenstrauss was the first mathematician from outside Poland to be awarded the Stefan Banach Medal of the Polish Academy of Sciences.{{cite web| url=https://www.impan.pl/en/events/awards/stefan-banach-medal| title=Stefan Banach Medal |publisher=Polish Academy of Sciences| url-status=live| archive-url=https://web.archive.org/web/20201105125729/https://www.impan.pl/en/events/awards/stefan-banach-medal|archive-date=2020-11-05}}
