Summary:Abstract: "This paper throws light on the connection between the optimal condition number estimate for the BPX method and constructive approximation theory. We provide a machinery, which allows to understand the optimality as a consequence of an approximation property and an inverse ineqality in H[superscript 1 + epsilon], [epsilon]> 0. This machinery constructs so-called approximation spaces, which characterize a certain rate of approximation by finite elements and relates them with interpolation spaces, which characterize a certain smoothness."
