James B. Carrell (1940, Seattle) is an American and Canadian mathematician, who is currently an emeritus professor of mathematics at the University of British Columbia, Vancouver, Canada. His areas of research are algebraic geometry, Lie theory, transformation groups and differential geometry.
He obtained his Ph.D. at the University of Washington (Seattle) under the supervision of Allendoefer. In 1971 together with Jean Dieudonné he received Leroy P. Steele Prize for his work Invariant theory, old and new.
He proved theorems in Schubert calculus about singularities of Schubert varieties. The Carrell–Liebermann theorem on the zero set of a holomorphic vector field is used in complex algebraic geometry.
He is a fellow of the American Mathematical Society.
