摘要
利用均值代替区间上函数值的方法离散具有弱奇异核k(s,t)=y(t)/|s-t|^(a)的Abel积分算子,得到了由该方法产生的投影算子,并证明了算法的合理性和有效性.
The Abel integral operators with weak singular kernel k(s,t)=y(t)/|s-t|^(a)are discretized by means replacing function values on interval,and the projection operators generated by this method are obtained,and the rationality and effectiveness of the algorithm are proved.
