MATHEMATICS COLLOQUIUM  Thomas Sinclair (Purdue University)
Topic: Abstract: A classical result of Eells–Sampson is that the set of harmonic maps in each homotopy class of maps between compact Riemannian manifolds, where the domain has nonnegative Ricci curvature and the target nonpositive sectional curvature, is nonempty and equal to the set of totally geodesic maps in that class. Hartman further proved that this set is pathconnected. It will be shown that these results generalize to energyminimizing maps into targets with no focal points. These are manifolds whose universal covers satisfy a simple synthetic condition: Each point and maximal geodesic are connected by a unique geodesic that intersects the latter perpendicularly. By contrast with previous approaches, the proof uses neither a geometric flow nor the Bochner identity for harmonic maps.
