    • A posteriori error control for fully discrete crank-nicolson schemes 

      B̈ansch E.; Karakatsani F.; Makridakis Ch. (SIAM Journal on Numerical Analysis, 2012-12-31)
      We derive residual-based a posteriori error estimates of optimal order for fully discrete approximations for linear parabolic problems. The time discretization uses the Crank- Nicolson method, and the space discretization ...
