Partial regularity for two dimensional Landau-Lifshitz equations. (English) Zbl 0906.35025

It is considered an initial value problem for the two-dimensional Landau-Lifshitz equation \[ \partial_t u=\alpha u\times \partial_t u+\beta \Delta_Mu+\beta | du|^2 u \] on \(M\times \mathbb{R}^+\), where \(M\) is a compact two dimensional Riemannian manifold without boundary. It is proved existence and uniqueness of a weak solution which is smooth with the exception of at most finitely many points.
