What Columbia University professor proved the Earle-Hamilton fixed-point theorem with Clifford Earle in 1968?
Earle–Hamilton fixed-point theorem In mathematics, the Earle–Hamilton fixed point theorem is a result in geometric function theory giving sufficient conditions for a holomorphic mapping of an open domain in a complex Banach space into itself to have a fixed point. The result was proved in 1968 by Clifford Earle and Richard S. Hamilton by showing that, with respect to the Carathéodory metric on the domain, the holomorphic mapping becomes a contraction mapping to which the Banach fixed-point theorem can be applied.
Carol Wood Carol Saunders Wood (born February 9, 1945, in Pennington Gap, Virginia) is a retired American mathematician, the Edward Burr Van Vleck Professor of Mathematics, "Emerita", at Wesleyan University. Her research concerned mathematical logic and model-theoretic algebra, and in particular the theory of differentially closed fields.
