摘要：
A simple criterion that allows the efficient local coarsening of simplicial finite element meshes generated by bisections is devised and analyzed. Under a mild condition on the initial triangulation the proposed criterion allows to gradually reverse the entire refinement without employing its history explicitly. Numerical experiments underline the efficiency of the resulting algorithm.
