利用定义出n阶的Kantorovich—Sheffer算子．研究它的有关性质。
Let h(t)=and exp(xh(t))=For f ∈ Lp[0,1],theasscociated Kantorovich-Sheffer operator of degree n is defined by f(u)dubnk (x), where pn=.The necessary andsufficient condition insuring the uniform convergence of f to f is given and, when h is apolymomial, an upper bound for the error is given.
