摘要:We study the energy critical equivariant Landau-Lifschitz flow with target manifold S^2. We prove that there exists a codimension one smooth well-localized set of initial data which generates finite-time type-II blowup solutions, and then give a precise description of the corresponding singularity formation. In our proof, both the Schr?dinger part and the heat part play important roles in the construction of approximate solutions and the mixed Energy-Morawetz arguments. However, the blowup rate is independent of their coefficients. This talk is based on the joint work with Jitao Xu.
