Quasi-optimal error estimates for the approximation of stable harmonic maps
Sören Bartels, Christian Palus, Zhangxian Wang
Based on a quantitative version of the inverse function theorem and an appropriate saddle-point formulation we derive a quasi-optimal error estimate for the finite element approxim…

Error analysis for the numerical approximation of the harmonic map heat flow with nodal constraints
Sören Bartels, Balázs Kovács, Zhangxian Wang
An error estimate for a canonical discretization of the harmonic map heat flow into spheres is derived. The numerical scheme uses standard finite elements with a nodal treatment of…

Orthogonality relations of Crouzeix-Raviart and Raviart-Thomas finite element spaces
Sören Bartels, Zhangxian Wang
Identities that relate projections of Raviart-Thomas finite element vector fields to discrete gradients of Crouzeix-Raviart finite element functions are derived under general condi…
