论文摘要
相对于雅各比权重函数$ w^{α,β}(t)=(1-t)^α(1+t)^α(1+t)^β$,$β$,$α,$α,β> -1 $,对间隔$ [-1,1] $的集成的错误估计值$ w^{α,β}(t)=(1-t)^α(1+t)此估计值适用于属于加权空间的某些sobolev型子空间$ l_ {w^{α,β}}}^1([ - 1,1])$。
An error estimate for the Gauss-Lobatto quadrature formula for integration over the interval $[-1, 1]$, relative to the Jacobi weight function $w^{α,β}(t)=(1-t)^α(1+t)^β$, $α,β>-1$, is obtained. This estimate holds true for functions belonging to some Sobolev-type subspaces of the weighted space $L_{w^{α,β}}^1([-1,1])$.
