Title: Stable-stationary harmonic maps to spheres Speaker: Changyou Wang, University of Kentucky Time, date, place: 2-2:50pm, Tuesday, 17 January 2006, POT 845. Abstract: In this talk I will prove a sharp version of the improved Kato's inequality for harmonic maps between two manifolds, and then apply it to show a new estimate on the Hausdorff dimension of singular set for stable-stationary harmonic maps into spheres. This is joint work with Fang-Hua Lin.
