Abstract: | With
, we here construct, for each positive integer N, a smooth function
of degree zero so that there must be at least N singular points for any map that minimizes the energy
in the family
. The infimum of over U(g) is strictly smaller than the infimum of over the continuous functions in U(g). There are some generalizations to higher dimensions.Research partially supported by the National Science FoundationResearch supported by an Alfred P. Sloan Graduate Fellowship |
