Gustav A. Hedlund

Gustav Arnold Hedlund (* 1904 in Somerville, Massachusetts, † 1993 ) was an American mathematician.

Life and work

Gustav Hedlund in 1930 received his doctorate in Marston Morse at Harvard ( " 1 Geodesics on a Two -Dimensional Riemannian Manifold with Periodic Coefficients 2 Poincare 's Rotation Number and Morse 's Type Number "). He was a professor at Yale University.

1933/34, 1938, 1939 and 1953/54, he was at the Institute for Advanced Study.

Hedlund was with his teacher Morse one of the founders of the topological ( " symbolic " ) dynamics, for example, the ergodic properties of the geodesic flow on manifolds of negative curvature treated.

His PhD is one of Walter H. Gottschalk.
