First, we present the equivalent variatial formulations of the least - squares mixed method and prove the existence and uniques for the weak problems. on the basis of l2 - projections and raviart - thomas projections, we obtain the superconvergence of the least - squares mixed finite element approx - imations on uniform triangulations, where triangular mixed finite elements of the lowest order raviart - thomas spaces are used to approximate the flux p. in the second chapter, we briefly recall the standard and mixed finite methods for second order elliptic problems, and introduce a modified least - squares mixed method
作者首先導出了最小二乘混合元方法的等價變分形式，並且證明了變分問題廣義解的存在唯一性；在此基礎上，我們採用強一致三角形剖分，選取最低階的raviar - thomas空間對未知函數的通量進行逼近，利用l ~ 2投影和raviart - thomas投影，得到了插值投影和最小二乘混合元解之間的超收斂結果。
