摘要:
This talk presents a posteriori error estimates of finite elements in H(curl) and H(div) problems based on auxiliary H(grad) space preconditioning, which is a continuous analogue of Hipmair-Xu preconditioner on the continuous level. In particular, we obtain novel parameter-robust and polynomial-degree-robust a posteriori error estimates in H(curl) and H(div) spaces. The material is based on joint work with Ludmil Zikatanov.
