Randall Dougherty

Randall Lee Dougherty ( b. 1961 ) is an American mathematician.

Dougherty won three times the U.S. Mathematical Olympiad (1976, 1977, 1978 ) received a gold medal in 1977 and 1976 and 1978, a silver medal at the International Mathematical Olympiad and was a three time winner of the Putnam competition ( 1978, 1979, 1980). He received his doctorate in 1985 at the University of California, Berkeley, with Jack Silver (Narrow Coverings of Omega Product Spaces ) He is a professor at Ohio State University.

Dougherty deals with different areas of mathematics, including set theory, real analysis, coding theory, computational geometry.

In 1994, he sparked a sixty- year-old problem of Edward Marczewski with Matthew Foreman: they showed that the Banach - Tarski decompositions of the unit sphere with Baire property exist ..

In 2005 he showed that linear codes have no optimal suitability for use in networks ..
