Organisers: Zhaonan Dong (Inria Paris), Alexandre Ern (Ecole des Ponts, Paris), André Harnist (Inria Paris), Ani Miraçi (Vienna University of Technology), Jan Papež (Czech Academy of Sciences, Prague), Ari Rappaport (Inria Paris), and Martin Vohralík (Inria Paris)

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
