Verification of functional a posteriori error estimates for obstacle problem in 2D
Petr Harasim, Jan Valdman
We verify functional a posteriori error estimate proposed by S. Repin for a class of obstacle problems. The obstacle problem is formulated as a quadratic minimization problem with…

Verification of functional a posteriori error estimates for obstacle problem in 1D
Petr Harasim, Jan Valdman
We verify functional a posteriori error estimate for obstacle problem proposed by Repin. Simplification into 1D allows for the construction of a nonlinear benchmark for which an ex…
