Main topics
A posteriori error estimates and adaptivity for
- numerical discretizations of partial differential equations
- linear algebraic solvers
- particularly their interplay (stopping criteria, design of adaptive h or p refinement under inexact solvers, design of algebraic solvers on hp grids)
- h and p robustness
- material properties robustness
