摘要

在本文中,我们引入并研究了一个新的正线性算子序列,它既作用于连续函数的空间,也作用于$[0,1]$上的可积函数的空间。我们给出了这个序列的一些定性性质,并证明了它在$C([0,1])$和$L^p([0,1]$)$中都是一个近似过程,还提供了收敛速度的一些估计。此外,我们确定了一个渐近公式,并且作为一个应用,我们证明了算子的某些迭代收敛于极限半群,无论是在$C([0,1])$中,还是在某些情况下,在$L^p([0,1]$)$中。最后,我们证明了在适当的假设下,我们的算子比文献中现有的算子表现得更好。

A Sequence of Kantorovich-Type Operators on Mobile Intervals
In this paper, we introduce and study a new sequence of positive linear operators, acting on both spaces of continuous functions as well as spaces of integrable functions on $[0, 1]$. We state some qualitative properties of this sequence and we prove that it is an approximation process both in $C([0, 1])$ and in $L^p([0, 1])$, also providing  some estimates of the rate of convergence. Moreover, we determine an asymptotic formula and, as an application,  we  prove that certain iterates of the operators converge, both in $C([0, 1])$ and, in some cases,  in $L^p([0, 1])$, to a limit semigroup. Finally, we show that our operators, under suitable hypotheses, perform better than  other existing ones in the literature.
