Richard Beals (mathematician)
Richard William Beals (28 May 1938, Erie, Pennsylvania) is an American mathematician who works on partial differential equations and functional analysis. He is known as the author or co-author of several mathematical textbooks. Beals studied at Yale University earning a B.A. in 1960, an M.A. in 1962, and a Ph.D. in 1964 under Felix Browder with thesis "Non-Local Boundary Value Problems for Elliptic Partial Differential Operators". In the academic year 1965/1966 he was a visiting assistant professor at the University of Chicago, where he became in 1966 an assistant professor and later a professor. In  1977 he became a professor at Yale University. Beals works on inverse problems in scattering theory, integrable systems, pseudodifferential operators, complex analysis, global analysis and transport theory. He has been married since 1962 and has three children. He should not be confused with the mathematics professor at Rutgers University named R. Michael Beals (born in 1954), who is Richard Beals's brother.
