Peter Hammer (mathematician)

from Wikipedia, the free encyclopedia

Peter Ladislaw Hammer , temporarily published as Petru Ivanescu, (born December 23, 1936 in Timișoara , † December 27, 2006 at Princeton , New Jersey ) is a Romanian-American mathematician who deals with combinatorics and operations research .

Life

Hammer studied at the University of Bucharest , where he graduated in 1958 and obtained his doctorate in 1965 under Grigore Moisil ( Pseudo-Boolean Programming and its Applications ). In 1961 he married Anca Ivanescu and during this time took her last name for a while. With her he had two sons. In 1966 he received the George Tzitzeica Prize from the Romanian Academy of Sciences. In 1967 he went to Israel with his wife, where he became a professor at the Technion in Haifa . In 1969 he went to Canada as a professor at the University of Montreal (he also became a Canadian citizen). In 1972 he moved to a professorship at the University of Waterloo and in 1983 at Rutgers University . He became a US citizen and founded the Rutgers University Center for Operations Research (Rutcor) at Rutgers University. He also played an important role in bringing DIMACS to Rutgers University. He died in a car accident near Princeton in 2006.

He is known for fundamental work in the theory of Boolean functions and pursued its application in many areas (graph theory, integer programming, operations research). He also used pseudo-Boolean functions in data mining and in data analysis (Logical Data Analysis, LDA). He was the author or editor of 19 books and over 240 scientific articles.

In 1998 he received the Euler Medal with Anthony JW Hilton . He was co-editor of Discrete Mathematics, Discrete Applied Mathematics, Discrete Optimization, Annals of Discrete Mathematics, Annals of Operations Research, and the SIAM Monographs on Discrete Mathematics and Applications. He was an honorary doctor of the ETH in Lausanne, the University of Rome (La Sapienza) and the University of Liège. He was a founding member of the Institute of Combinatorics and its Applications and he was a Fellow of the American Association for the Advancement of Science .
