The Classification of Branched Willmore Spheres in the -Sphere and the -Sphere
We extend the classification of Robert Bryant of Willmore spheres in to
variational branched Willmore spheres and show that they are inverse
stereographic projections of complete minimal surfaces with finite total
curvature in and vanishing flux. We also obtain a classification
of variational branched Willmore spheres in , generalising a theorem of
Seb\'{a}stian Montiel. As a result of our asymptotic analysis at branch points,
we obtain an improved regularity of the unit normal of variational
branched Willmore surfaces in arbitrary codimension. We also prove that the
width of Willmore sphere min-max procedures in dimension and , such as
the sphere eversion, is an integer multiple of .Comment: 74 pages, 1 figur
Weak closure of Singular Abelian -bundles in dimensions
We prove the closure for the sequential weak -topology of the class of
vectorfields on having integer flux through almost every sphere. We show
how this problem is connected to the study of the minimization problem for the
Yang-Mills functional in dimension higher than critical, in the abelian case.Comment: 29 pages, some typing errors fixe
