A Note on a Posteriori Error Bounds for Numerical Solutions of Elliptic Equations with a Piecewise Constant Reaction Coefficient Having Large Jumps

We have derived guaranteed, robust, and fully computable a posteriori error bounds for approximate solutions of the equation , where the coefficient is a constant in each subdomain (finite element) and chaotically varies between subdomains in a sufficiently wide range. For finite element solutions,...
