## Abstract We study intrinsic biharmonic maps on a fourβdimensional domain into a smooth, compact Riemannian manifold. We prove a partial regularity result without the assumption that the second derivatives are squareβintegrable. Β© 2005 Wiley Periodicals, Inc.

β¦ Synopsis
In this article we prove the regularity of weakly biharmonic maps of domains in Euclidean four space into spheres, as well as the corresponding partial regularity result of stationary biharmonic maps of higher-dimensional domains into spheres.

We present an elementary argument of the regularity of weak harmonic maps of a surface into the spheres, as well as the partial regularity of stationary harmonic maps of a higher-dimensional domain into the spheres. The argument does not make use of the structure of Hardy spaces.
+ 1 scalars control the (n Γ n)-dimensional matrix Dv). For instance, typical theorems are: THEOREM 0.1 If v is bounded and div v and curl v belong to C k, Ξ± (or W k, p ), so does all of Dv, and its C k, Ξ± (or W k, p ) norm is controlled by that of div and curl. Another form of the same theorem is
The question of when a given graph can be the underlying graph of a regular map has roots a hundred years old and is currently the object of several threads of research. This paper outlines this topic briefly and proves that a product of graphs which have regular embeddings also has such an embeddin
