Roger Maddux (born 1948) is an American mathematician specializing in algebraic logic.He completed his B.A. at Pomona College in 1969, and his Ph.D. in mathematics at the University of California in 1978, where he was one of Alfred Tarski's last students. His career has been at Iowa State University, where he fills a joint appointment in computer science and mathematics.Maddux is primarily known for his work in relation algebras and cylindric algebras, and as the inventor of relational bases.His Erd s number is 2. In mathematics and abstract algebra, a relation algebra is a residuated Boolean algebra expanded with an involution called converse, a unary operation. The motivating example of a relation algebra is the algebra 2X² of all binary relations on a set X, that is, subsets of the cartesian square X2, with R S interpreted as the usual composition of binary relations R and S, and with the converse of R interpreted as the inverse relation.
