【摘要】 <正> 1.引 言 设(X,‖·‖)为赋范线性空间,H为X→X的线性连续算子类,使得方程 z=Hz+f (1)对于一切H∈H,f∈φ X有唯一解.将此类方程记为[H,φ]. Sobolev将寻求(1)的近似解归结为解一个有限维代数方程组的方法称为直接方法.因此,直接方法就是一种算更多还原

【Abstract】 In this paper it was considered that problem of optimization of adaptive direct algorithm of approximate solution of integral equations. For the Fredholm integral equations of second kind with kernels belonging to Besov classes there is determined the exact order of the error of an optimal adaptive direct algorithm and a algorithm for realizing it is indicated.更多还原
