Stanisław Radziszowski
From Wikipedia, the free encyclopedia
Stanisław Radziszowski (born June 7, 1953) is a Polish-American mathematician and computer scientist.
Radziszowski was born in Gdańsk, Poland, and received his PhD from the Institute of Informatics of the University of Warsaw in 1980. His thesis topic was "Logic and Complexity of Synchronous Parallel Computations". From 1976 to 1980 he worked as a visiting professor in various universities in Mexico City. In 1984, he moved to the United States, where he took up a position in the Department of Computer Science at the Rochester Institute of Technology.
Radziszowski has published many papers in graph theory, Ramsey theory, block designs, number theory and computational complexity.
In a 1995 paper with Brendan McKay he determined the Ramsey number R(4,5)=25. His survey of Ramsey numbers is a standard text on the subject.
Among students and faculty he is affectionately called 'Staszek' or referred to as 'The Radish'. Staszek is the standard Polish nickname for Stanisław (see List of Polish given names), and 'The Radish' comes from students who have problems pronouncing Professor Radziszowski's last name.
