Superconvergence
http://dbpedia.org/resource/Superconvergence
In numerical analysis, a superconvergent or supraconvergent method is one which converges faster than generally expected (superconvergence or supraconvergence). For example, in the Finite Element Method approximation to Poisson's equation in two dimensions, using piecewise linear elements, the average error in the gradient is first order. However under certain conditions it's possible to recover the gradient at certain locations within each element to second order.

数値解析において超収束 (ちょうしゅうそく、Superconvergence) とは、常微分方程式の数値解法・偏微分方程式の数値解法において通常より収束が早くなる現象をさす。このような現象は有限要素法・選点法やShortley-Weller近似 (差分法の一つ)などで見られる。
